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.
