In recent years , as China's rapid development of infrastructure in mountainous areas , there has been a lot of high slope engineering problems , both increased investment, but also delay the construction period , and even cause damage to existing projects . High slope is part of the geological transformation of human engineering , the stability is not only controlled by lithology, geological structure, rock structure , hydrogeological conditions of the slope where the basic characteristics of rock and soil , but also controlled by the excavation slope, slope shape and other human transformation degree . As the complexity of the geological body , multi- variability and heterogeneity, making high slope stability analysis is very complicated ; while changing due to geological conditions , no one can fully apply the existing slope engineering experience , which determines the high slope uniqueness problem , we must analyze specific issues . In this paper, southern Yunnan Geological Corporation \geological data and engineering geological characteristics of in-depth research study based on the analysis of ZK86 No. slope of the study area where the lithology, meteorological and hydrological characteristics , geological features, and new tectonic movement and seismic characteristics , the use of anti algorithms and indoor test statistics to determine weathered rock containing clay shear strength values , and using stereographic projection method , FLAC3D finite difference method, the limit equilibrium method, finite element strength reduction ZK86 No. slope stability analysis , and sub-station open after digging the stability factor is calculated for the rational choice approach to slope supporting a basis . The results showed that: topography, lithology is the impact of the high slope stability of the main factors , human activities are the main predisposing factor ; slope will be in an unstable state in the excavation , slope excavation conditions with sub-station , should adopt the anchor frame beam support method . This theory and practice , the system summarizes the high slope engineering studies and methods of the main contents of the selected work sites representative , the findings for the infrastructure encountered mountain slope stability analysis and management to provide technical support .
