Analysis Of The Stability Of Rock-slope

The stability of rock slope is very important in hydraulic , hydroelectric, railway and highway engineering. This problem can directly influence on construction time, investment and environment, and which involves a lots of knowledge such as geological, rock-soil, construction and environment protection.With the background of the plantback slope of the expanded project of Zhelin hydropower station, which located in Jiangxi Province, this paper mainly analyzes the characters of engineering and hydrologic geology condition, the stability of slope, the feature of deformation and the the failure mechanism of rock slope. The main research contents are listed as follows:(1) To establish a simple geology mode of rock slope and analyze the failure model of plantback slope by collecting the relevant engineering and hydrologic geology condition as many as possible and applying geology mechanics method and comparable engineering experience;(2) To take insight into deformation characters , plastic zone distribution and the the failure mechanism of rock slope in two sections in plantback slope by the non-linear finite element method;(3) To find the latent slide plane in rock slope according to the engineering geology conditions , the comparable engineering experience and the plastic zone distribution computed by the finite element method;(4)To discuss the arrangement principle of safety monitoring instruments in engineering slopes, analyze the deformation data acquired by the monitoring instruments, study the stability of slope during digging and the actual deformation characters of slope and make a contrast with the results acquired by limited equilibrium method and finite element method.
