Round foundation pit force has obvious spatial effect. In order to quantify space effect to reasonable application in practical engineering, using the current specification of "plane vertical elastic foundation beam" concept, and using elastic cylinder by uniform load, the arch effect equivalent stiffness coefficient is deduced, with is the current engineering support design software in the virtual support required important parameters, so as to realize the quantification of round arch effect. This method and the three-dimensional continuous medium finite element method are compared and analyz...
