摘要
结合兰州市轨道交通1号线一期工程奥体中心站附属人防工程开发项目,采用Flac软件,对基坑施工步骤采用三维地层结构模型模拟,分析人防工程施工引起的既有隧道的变形及内力,评估隧道结构的安全性,为类似工程提供参考。
With the civic air defense project attached to the first-term project——the Olympic Sports Center Station of the 1st Rail Transit Line of Lanzhou City——as a practical example,a 3-dimensional stratum structure model is adopted to simulate the construction steps of the foundation pit,with the possible civic-air-defense-project-caused deformation and internal forces of the existing tunnel analyzed,upon the basis of which the security of the existing tunnel structure is evaluated.The paper may serve as a useful reference for other similar projects.
