摘要
岩溶发育地质中的嵌岩桩,由于溶洞的存在,其受力机理与承载特性非常复杂。利用ABAQUS有限元分析软件,分析研究岩溶发育地质中溶洞对嵌岩桩的承载特性的影响,设计了四种不同的数值模拟分析对比方案,得出了岩溶地质中嵌岩桩的不同承载特性及桩侧摩阻力和桩端阻力的规律性结果,能使桩基设计达到优化的目的。
Rock-socked pile in karst geology, due to existence of karst cave, has complex force mechanism and bearing characteristics. In this paper, with ABAQUS finite element analysis software, the effect of karst cave developed in karst geology on bearing characteristics of rock-socketed pile is analyzed to the extent that four numerical simulation schemes for comparison are designed. As a result, regularity of bearing characteristics, side friction and end resistance of such rock-socketed pile are obtained and the pile foundation design could be optimized.
