西安出露及隐伏地裂缝与地铁隧道相互作用数值模拟分析
A Numerical Simulation of Interactions between Ground Fissures and Xi'an Metro Tunnel
摘要
Abstract
With the launching of the Xi'an Subway Engineering, Xi'an ground fissures have become an urgent important scientific problem need to solve. In order to better reflect the actual situation and compare the result of large-scale physical model tests with ground fissure, this paper established two tunnel numerical simulation models between ground fissure and buried ground fissure. The result shows that; the influence scope and depth is much larger in the buried ground fissure; the soil vertical displacement of the side surface is mainly due to friction between the upper and the lower soil in the ground fissure model; but in the buried model, the displacement is due to soil subsidence resulting in the overlaying soil deformation; The vertical displacements of the shield lining arch in the two models are "s" curves. But the shield lining deformation degree is much larger in the ground fissure model.关键词
