摘要: 针对覆盖型岩溶发育区地面稳定性评价问题,提出一种新的岩溶地面塌陷稳定性评价方法。依据唐山市岩溶勘察与地灾评估资料,以岩溶发育区地面稳定情况为因变量,选取5个主要影响因素作为自变量,建立了岩溶地面塌陷稳定性评价的二分类Logistic回归模型。模型拟合优度、预测能力和模型稳定性检验表明,该模型预测能力强,预测结果与实际情况吻合度良好。所建模型能对定性因素进行定量分析,易于获取评价因子,可简便地、快捷地对与唐山岩溶发育区相似区域的岩溶地面塌陷稳定性给出评价,值得推广和应用。

Abstract: A new method for assessment of karst ground collapse stability is presented for ground stability assessment at a covered karst area. Based on data of karst geological survey and karst disaster assessment from Tangshan city, the ground stability condition is investigated; and 5 major factors that might affect the karst ground stability are selected as independent variables, and then a logistic regression model for stability assessment of karst ground collapse is established. This model not only meets goodness-of-fit test, but also have good performance in stability and forecast accuracy. The presented model can carry out the quantitative analysis for qualitative factors, and the factors investigated are relatively easy to obtain; thus the logistic regression method for karst ground collapse stability can be widely applied to covered karst area.

Key words: karst, ground collapse, stability assessment, analysis of Logistic regression
