摘要
结合工程实例,按两个行业标准和两个地方标准,对比分析了地铁基坑坑底抗隆起稳定性验算结果,并通过有限元分析,对基坑的坑底隆起、围护结构变形、地表沉降等进行了验证计算,提出了长条形基坑坑底抗隆起稳定性验算模式的适用条件与计算参数的取值建议。
In this article, stability analyses against foundation pit heaving are conducted based on two industry standards and two local standards using finite element model calculation, foundation pit heaving, retaining structure deformation, ground settlement are achieved. By comparing the results to project experience, the author brings up his opinion and suggestion on determine the application condition, calculation parameter and safety factor for analysis on strip shaped foundation pit stability against heaving.
