摘要：
How to improve the capacity of the signalized intersections is, one of the most important majors at recent Years. At home and abroad though the waiting-area for left-turn vehicles has been settled, the spare area of the intersection isn't made good use to increase the capacity of the intersection. This paper do some work on the waiting-area for through vehicles and the second stop-line, at the same time gives some improvement advice on the organization of the pedestrian at intersection. Both the theory study and practice have proved that the settlement of waiting area for through vehicles can improve the capacity of the signalized intersections greatly, and ensure the pedestrian's safely when they come cross the intersection, So it with have a good prospect Of application and extension.

摘要：
With the continuously deepen of internationalization degree of oil field exploitation project, economic evaluation plays a vital role during the oil field development. In the process of oil field evaluation, net present value (NPV) is an important index, which reflects the economic benefit as a whole. The paper represented the technical and economical characteristic of Oilfield development project and gave out the main economic index calculation method. By analyzing the oilfield investment project, it is suggested that the total net present value should be used to evaluate the economic benefit in oilfield investment project. From the example study, it is found that the results got by the total NPV method is much similar to the results which calculated by intersecting method. The total NPV method is simple compared with other method, and is easily to learn and use in oilfield investment project evaluation.

摘要：
The artery control system is an important part of urban traffic control. Based on the analysis of the actuality of traffic, the optimization scheme of its artery control system on Jianshe Boulevard in Wuhan is put forward in this paper. First optimizing the signal timing of each single-point intersection, then we design the two-way green wave system. In the end the software Vissim is adopted to evaluate the scheme.

摘要：
Knowledge management is the recognition of the knowledge value in a totally new sense. It is a new management model based on the functional division of knowledge. Knowledge management is a new management model that appears in recent years, This paper analyzes the current situation of our country's construction industry, then this paper analyzes the origin, development, character and enforcement of the knowledge management, so it is very necessary to use knowledge management, then this paper puts forward the measures of using knowledge management to promote construction industry innovation and development, knowledge management will improve the innovation ability and core competition ability of construction industry.

摘要：
Hydraulic fracture technique, as a main measure, has been widely used for stimulation of oil and gas reservoirs by creating a propped conductive channel. However, the mechanism and propagation process of hydraulic fracture have not clearly known to us. According to fluid mechanics in porous media, rock mechanics, heat transferring theory and fracture mechanics, the authors removed many hypotheses in common 2 - dimensional model and deduced a three-dimensional model of hydraulic fracture. The injected fluid is assumed to be an incompressible power-law type non-Newtonian fluid and to be 2 - dimensional laminar flow in the fracture. The governing equation of the fracture flow is derived from its continuity, momentum and constitutive equations. The fracture criterion is based on a stress intensity factor approach. The finite element formulas are gained by employing the standard Galerkin approximation. Through numerical simulation, parametric sensitivity investigations are performed to illustrate the role of different variables on hydraulic fracture configuration evolution in oil formations.
摘要：
In order to analyze mechanism of casing damage, the uniaxial compression experiment and creep experiment of interbedded mudstone samples from Sanan development area of Daqing Oilfield under different water contents were carried out. The changes of the mudstone’s mechanical parameters and creep characteristics with the increment of water saturation were studied. The results indicate that the rock strength and elastic modulus decrease rapidly with the increment of water content, at the same time, the creep strain and creep strain rate of steady state increase with the increment of water content, and also the steady state creep strain rate is enhanced with the increment of deviatoric stress. Through the creep characteristic curves, a non-linear creep constitutive equation of mudstone considering the change of water contents is established, which will be used in future numerical analysis.

摘要：
The new approach for vendor selection problem was established under the stochastic environment. After establishing the traditional multi-objective programming model, through minimizing the optimistic value of the net cost of the total order quantity, rejected quantity and late delivered quantity, the multi-objective stochastic constrained integer programming model was established based on the stochastic chance constrained programming theory, then a hybrid intelligent algorithm was designed by integrating the stochastic simulation, neural networks and genetic algorithm. The numerical example confirms the model is rational and the algorithm is valid. The stochastic constrained programming approach is feasible. It can solve the vendor selection problem.

摘要：
Steam injection process has been widely applied to enhance oil rate in thermal heavy oil production. But the different well structures have large influence on casing stress distribution, especially on bent part, which can reduce casing service life. During steam injection, the casings with different well structure sustain different thermal stress, especially to bent casing, which can cause casing damage and severely affect oil production and economic benefit. The influence of well structure on stress distribution of bent casing in thermal production horizontal well was studied through numerical simulation. The results can provide theoretical guidance to analyze casing stress status and prevent casing damage.
摘要：
The construction of prestressed high-strength concrete pipe pile can be performed by static pressure and hammer striking. As a rapidly-developing way of construction pile foundation, liquid static pressure has the advantages of less noise pollution, no environmental pollution and thus meets the needs of environmental protection in modem cities. On the other hand, large liquid static pressure machinery demands greater bearing capacity and smoothness of the worksite due to its heavy weight. This paper mainly deals with how to reduce squeezing effect on the piling and its quality and the moving of large liquid static machinery on soft ground and therefore provides some references for the operation in similar cases.

摘要：
Each bank has taken many measures to retain existing customers, but as for the current financial market, the bank customer dropout of our commercial banks is a common phenomenon, the root of which rests on that many banks haven't correctly distinguish the main reasons and secondary reasons for the dropout of customers when establishing the measures, so those measures are lack of focus. This article analyzes the correlation degree for the bank customer dropout to each related factors and get the ordering of correlation degree for each factors to the customer dropout based on Fuzzy Clustering and Grey Theory so that our banks can find out the main factors of customer dropout right, take focused measures and eventually enhance the effectiveness of measures to avoid the customer dropout.
摘要：
The coupling model of water's flowing in pipes and migration in soil body was built on the theory of fluid mechanics in porous media and hydrodynamic theory. Navier-Stokes equation was used to control the flowing of water in percolation irrigation pipes, and Darcy's law was used to simulate the migration of water in soil body. COMSOL Multiphysics which is multi-physical analyzing software was adopted, and the set-up numerical model was simulated and analyzed. The results showed that it was suitable when pressure head was 2m and the distance between plastic pipe and crop roots was 30mm.
