摘要
岩溶地区基础荷载下的溶洞,能否保持自身的稳定,将直接影响着上部结构物的安全使用。目前溶洞稳定性分析方法中,经验性的成分太多。文中采用弹性理论对基础下溶洞的稳定性问题进行分析,提出一种新的定量分析方法,为基础荷载下的溶洞是否需要处理提供理论依据。
Stability of cavity under foundation load in karst area directly influences safety service of upper structure.At present,cavity stability is mainly based on empirical analysis.This paper analyzes cavity stability under foundation load using the theory of elasticity and puts forward a new quantitative analysis method to provide theoretical basis for the necessity of cavity treatment under foundation load.
