摘　　要：本文通过研究三维拱顶型溶洞顶板厚度及跨度对桩基承载力的影响,建立三维有限元整体地层模型,利用数值模拟方法,研究不同顶板厚度及不同溶洞跨度下对桩基承载力的关系。In order to study the influence of roof thickness and span of three-dimensional vault karst cave on the bearing capacity of pile foundation,this paper establishes the three-dimensional finite element integral stratum model and uses the numerical simulation method to study the relationship between different roof thickness and different karst cave span on the bearing capacity of pile foundation.

关 键 词：岩溶 顶板厚度 桩基承载力 有限元分析
