| 摘 要： | 利用有限元分析的方法,着重讨论了岩溶地区桩基承载力的主要影响因素,包括溶洞体积的大小、顶板厚度以及岩性对桩基承载力的影响。分析结果表明:在主要影响因素中,溶洞高度大小对顶板稳定性影响较小,溶洞顶板跨度、顶板厚度影响较大。而围岩的性质最为明显。这种方法也为岩溶地区桩基承载力的确定提供了新的途径。

| Abstract: | This paper,based on the finite element method,discusses the major factors influencing pile bearing capacity in karst area which include the size of the cave,carrying slab thickness and the strength of rock.According to the analysis,the quality of the rock around the cave is most important of all the factors.The influence of the span of cave and the thickness of the slab is obvious.And the influence of cave height is limited.This method also provides the new way for determining the bearing behavior of pile in Karst area. |
