Research On The Stability Of Huang Junwan High Slope In Pu Erdu Town, YanJin Country, Yun Nan

In this article, it takes the Potential Unstable Rock Mass in High Slope project as the research object which is located in Huangjue wan, Pu’er du town, yanjin country of Yunnan Province. In addition, does the detailed introduction on the several aspects about geographical conditions, meteorological and hydrological, topography, lithology, regional geological structure, geological conditions of water level, Regional stability and earthquake action of the Potential Unstable Rock Mass in High Slope project. It turns out that the stability of the Potential Unstable Rock Mass in High Slope mainly includes two issues:(1) The stability problem of the rock mass on the slope;(2) The stability of the giant stone that accumulates on the surface of the main slope. This article first to summarized the development history of rock slope stability studies both at home and abroad and aslo about its analysis method, Combined with practical engineering have been chosen for the research methods and the engineering calculation software. In the stability calculation of the main rock slope,selected three typical geologival profile,using Geo-Studio software and FLAC2D to calculate the Gravity conditions and the seismicy load, The stability calculation in the giant stone of the main slope surface sediment selected four typical geologival profile,using Rockfall software.This article mainly obtains the following results includin:(1) In Gravity conditions, The safety coefficient of main rock slope is very high, the slope is in the steady state, But in the slope surface shape mutation is due to stress concentration, There are still possible local, small-scale failure;(2)In the seismicy load, The safety coefficient of main rock slope sharply, But the slope is still in steady state,deep rock slope may cause the possibility of the cutting layer to increase;(3) the giant stone of the main slope surface sediment once along the slope surface rolling again,will seriously endanger the safety of the Huang Jue Wan.The reaserach achievements of stability of Potential Unstable Rock Mass in High Slope, Provides the basis for engineering and technical personnel to carry out a reasonable design for the slope and the future of slope treatment and environmental restoration work has reference significance.
