摘要
运用有限元软件对多层岩溶地区大直径深水基桩在水平荷载作用下基桩的位移、内力进行数值分析。并将各种影响因素(溶洞的半径、高度、岩土弹模、桩基弹模、溶洞顶板厚度)下的分析结果进行比较,得出有若干有参考价值的结论。
The pile displacement and internal force of large diameter deep water pile under action of horizontal load in the multilayer karst region were numerically analyzed. The results affected by influence factors（including cave radius, height, rock and soil elastic modulus, pile foundation elastic modulus, cave roof thickness） were compared, thus obtaining some valuable conclusions.
