| 摘 要： | 在岩溶地质条件下,考虑上部结构与地基基础的相互作用,通过三维整体建模考虑变形协调。利用ANSYS有限元软件计算分析某一算例,通过改变溶洞半径、埋深、形状及改变溶洞围岩的弹性模量、泊松比及厚度,得出溶洞因素对上部结构应力的影响变化规律。

| Abstract: | In karst geological conditions, the paper consider the interaction of the superstructure and foundation of 3 D entirety modeling to consider the deformation compatibility. Using ANSYS finite element software to calculate a particular example, by changing the radius of the karst cave, buried depth, shape and changing the elastic modulus, Poisson＇s ratio and thickness of the surrounding rock of the karst cave in order to detect the superstructure stress of variation. |
