摘要

Xi’an, with its complexity and specific geologic condition, is the most representative city in the world for its ground-fissure, and these bring newly problems for the construction of subway lines.  In order to look into the ground-fissure spreading mechanics reason and extending characteristic in loess, the authors incorporated large-scale physical simulative experiment results with numerical simulation results to contrast, verify and check. The results show that both numerical simulation and physical simulative experiment about ground-fissure brought along constructional fracture mode substantial agreement, which implies the numerical simulation method is effective in ground-fissure spread analyses.
