软土地区的地铁车站深基坑工程因其施工环境复杂,施工风险大,施工风险因素之间的耦合作用,致使深基坑施工的主要风险难以确定,导致施工事故频发。本文基于深基坑工程类似施工风险经验,识别风险因素,按照工作分解结构分解方法,建立风险清单。采用层次分析法和专家调查法,分析深基坑施工风险因素的重要性及其主要风险,估计风险发生概率与风险损失。采用梯形隶属函数计算风险事件的隶属度,运用模糊综合评价法进行风险评估,确定施工的风险等级。通过对厦门某地铁车站深基坑工程施工风险进行实证研究,确定其施工总体风险等级为三级,属于风险可控制的范围,评价结果能反映实际施工风险情况。针对基坑施...

Due to the complex construction environment,the deep excavation of station foundation pits would inevitably cause the high risk in soft soil. It was difficult to determine the risk probability because of the coupling of risk factors,and the accidents were broken in foundation pit construction. In this paper,the risk factors were given based on in-situ experiences of similar engineering both in China and abroad. The risk list was established by identifying risk events or factors based on work breakdown structure (WBS). Expert investigation method and analytic hierarchy process (AHP ) were emplo...
