摘要
Abstract
This paper aims to master the stability of foundation pit settlemen accurately.The study consists of constructing a current evaluation model of foundation pit settlement stability by analyzing cusp mutation;constructing a development trend evaluation model of foundation pit settlement stability in the set pair analysis combined with prediction model;and comprehensively evaluating the stability of founda-tion pit settlement based on the both results.The results indicate that,based on the current evaluation of the stability of foundation pit settlement,the mutation characteristic values of each monitoring point are all greater than 0,indicating that under the current conditions,the overall settlement of the foundation pit is in a stable state.Meanwhile,by evaluating the development trend of foundation pit settlement stability,the extrapolation prediction rate of each monitoring point shows a decreasing trend compared to the current rate,and the subsequent settlement stability of the foundation pit tends to increase.Based on the current stability results and development trends of the foundation pit,the settlement stability of the foundation pit is currently in a stable state and tends to increase in later stage.关键词
