摘要
针对西安地铁在地裂缝活动条件下引起的工程问题,通过数值模拟,结合地裂缝区域的设计方案,分别从地表沉降位移、衬砌沉降位移、围岩位移场、围岩土压力、衬砌结构内力等方面,分析地裂缝活动条件下隧道结构与围岩变化特征和作用机理。
In view of the engineering problems of Xi＇an subway caused by the activities of ground fissures,surface subsidence,lining displacement,surrounding rock displacement field,surrounding rock pressure and internal forces of lining structure were analyzed by numerical simulation to explore the interaction mechanism between tunnel structure and surrounding rocks under the activities of ground fissures.
