| Based on extensively collection and reading about researching data of home and abroad, Combined the project of "Study on deformation monitoring and regulating countmeasures of geological hazards of basis construction in Chongqing ", the slump geological hazards of the main city zone are researched. There are many of contents and results in this paper.(1) The environmental geologic condition of slump geological hazards developing is analysed, such as meteorology hydrology, topography geomorphology, strata lithologic character, geologic structure, hydrogeology, neotectonic movement and earthquake etc.(2) The distributing laws of space and time and the main character of slump geological hazards are analysed based on introducing of the main city zone disasters developing status.(3) The main affecting factors of slump geological hazards developing are analysed, such as meteorology hydrology, the feature of rock and soil, rainfall, fluvial abrasion and raising and falling of water level, groundwater regime, earthquake activity, and human engineering activity.(4) Take a typical example for Maliuzui landslide in Banan district, according to its characteristic and monitoring result of the deformation, we model the concept of slide relive by analyzing the influencing factors and mechanism of slide relive; What's more, from analyzing its stability in the complex condition; we provide evidence for the evaluation of slope stability and father design.(5) Showing the crag and slide developing of Liziba-Hualongqiao sect in Yuzhong district, the evaluation of whose stability provides scientific evidence for geological hazards prevention-cure and decision-making of government .(6) Giving some examples, we analyze the application of these models,in the coast deformation forecast, such as optimized grey model ,NN model ,multinomial statistic model ,which can reach high accuracy and universal applicability.
