摘要
浅埋隧道地质条件复杂,如果支护形式采用不当,极易造成塌方等事故。然而隧道的受力分析又存在很多不确定的因素,很难准确把握。本文采用GeoFBA 4.0软件对地下浅埋隧道进行稳定性分析,模拟隧道的施工,计算岩土及地下工程施工前后地层的应力场、位移场以及支护结构内力。
Geological. condition of shallow-buried tunnel is complicated. If the form of support is adopted inadequately, it is easy to cause some accidents, such as collapse. Because many uncertain factors are existed in the analysis of force-bearing, it is very difficult to obtain the accurate data. GeoFBA 4.0 software is adopted in this paper to analyze the stability of underground shallowburied tunnel, simulate the tunnel construction; calculate the stress field and displacement field of stratum of geotechnical and underground engineering and support structure internal force.
