高层建筑物下隧道围岩应力的分析

为进一步发展利用地下空间,解决城市发展中的种种问题与矛盾.在结合重庆市某开发建设项目,对高层建筑物的地基基础与地下隧道围岩的相互作用进行分析的基础上,通过数值模拟,得到了隧道围岩的应力分布曲线,发现了应力集中的作用范围,为以后的工程设计和工程施工提供参考依据.

Analysis on the Stress of the Tunnel Underground High Buildings

With the problem of the city development, it becomes very important and urgent to research the utilization of the urban underground space. The authors discuss the interaction of high buildings and tunnel which belongs to a project at Dadukou region in Chongqing. The authors simulate this condition in computer and analyses the stress around the tunnel and find the rang of stress concentration. At last,the authors offer some references for underground-space opening of the tunnel under high buildings.
