塌落计算法在人防洞室稳定性评价中的应用

Application of the Cave-in Method on the Stability Judgement for Underground Shelter Cave

在城市的发展过程中,常常在建筑物基础下碰到人防洞室。如何正确地对人防洞室进行分析、计算与评价,关系到对人防洞室和建筑物的安全使用。文中采用传统的塌落计算方法对某无衬砌结构人防洞室稳定性进行了评价,这些研究成果除了能对工程的顺利实施起着十分重要的指导作用外,还可为以后类似工程积累经验和实践资料。

The underground shelter cave is often encountered under some foundations in urban regions.It is necessary to judge the safety of building foundation and underground shelter cave.In this paper,the cave-in method is applied to judge the stability of the underground shelter caves with no retaining structure.The study results not only serve as important inference to the construction of this case,but also accumulate experience and data for other similar engineering practices.
