摘　　要：为比较各因素对覆盖型岩溶稳定性的影响程度,通过对8个影响因素在不同参数下的正交试验,采用单因素分析法、多因素极差分析和方差分析相结合的方法研究各影响因素敏感性顺序。结果表明:土洞直径、覆盖层土体粘聚力以及覆盖层厚度是影响岩溶覆盖层稳定性的3个最主要因素,其他因素影响程度相对较低,为岩溶塌陷预警防治措施提供指导依据。To compare the influence degree of each factor on the stability of overlying karst,a single factor analysis method was made in the orthogonal test of eight influence factors under different parameters.A multi-factor range analysis and an analysis of variance were used to study the effects and factor sensitivity order.The results show that the diameter of the soil cave,the cohesion of the overburden soil and the thickness of the overburden are of three most important factors affecting the stability of karst overburden.The other factors have a relatively low degree of influence.
