摘    要:实践表明影响岩溶地基承载力的主要因素有溶洞大小和截面形状、溶洞位置和溶洞发育程度。采用数值模拟和正交试验相结合的方法,就单个因素对地基承载力的影响和多个因素对地基承载力的综合影响分别进行了模拟分析,结果表明溶洞大小和截面形状的影响最大,溶洞发育程度次之,溶洞位置的影响较小。

关 键 词:岩溶地基  承载力  影响因素  正交试验

Abstract:According to experience of many projects,bearing capability of karst ground heavily depend on the karst cave size and its shape,position,and the developing karst.Based on the numerical simulation and orthogonal tests,the effect of single factor and multi-factor on the bearing capability of karst ground is simulated in this paper.The research results show factors decided the bearing capability karst ground are karst cave diameter and its shape,degree of developed karst,karst cave position in sequentially.
Keywords:karst ground  bearing capability  influencing factors  orthogonal test
