镇江市土坡稳定性划分及分析评价

Classification Analyses and Evaluation on Stability of Soil Slope in Zhengjiang City

基于大量野外地质调查，将镇江市区的土坡（包括天然斜坡和人工边坡）划分为三种稳定性状态：稳定的、基本稳定的和不稳定的。通过对影响土坡稳定性的各种因素的分析，认为该区的斜坡破坏是自然条件及其演化与人类活动共同作用的结果。据此提出了各类坡体的整治建议。这一研究有助于该区的城市建设规划和斜坡地质灾害的防治。

The soil slopes(natural slopes and artificial slopes)in Zhengjiang city can be classified into three groups(stable slope,quasi stable slopes and instable slopes)based on the field geological investigation.Based on the analyses of effective factors for slope stability the slope failure are caused by mutualfunction of natural evolution and human activities.At the same time,the overall assessment and controlling measurements are presented.This research on slope stability of the area aims at supplying geoscientific basis for municipal programe and at prevention of slope hazards.
