| Abstract: | Through analyzing the conventional approaches for the numerical simulation of shield tunneling,a new FE simulation method based on the concept of ground loss has been developed.Its applicability was verified by comparing with the displacements obtained by analytical method and empirical prediction.The method was applied to simulate a shield to under-cross the existing subway with some deformation regularities of the subway tunnel obtained,which were compared with those of some other projects. |
