摘　　要：随着中国经济高速发展和加强对基本农田的保护,越来越多的大型火电厂建设于山区且多数为坑口电厂,一般会涉及到西南地区主要含煤地层二叠系上统龙潭组(P2l)。龙潭组是由海陆交替相含煤砂、页岩等软质、易滑地层构成的,在龙潭组岩层区建设坑口电厂大型山体滑坡等不良地质作用是不可回避的工程地质问题。本文以贵州省某电厂大型山体滑坡对工程场地适宜区域划定的影响研究为出发点,认为山区坑口电厂建设中对大型山体滑坡的分析评价只要遵守查明基本地质条件,评价滑坡稳定性,划定适宜建设区域,提出处理建议的基本工作流程,大型火力电厂在大型山体滑坡附近建设是可行的。Because Chinese economy grows faster and Chinese government protects basic farmland more strictly, more and more fossil fuel power plants, most of which are large size pithead power plants, are built in mountain area. In southwestern mountainous areas of china, pithead power plants are usually built in Permian Longtan group stratum area. Permian Longtan group stratum is sedimentary deposit which consists of sandstone layer, mudstone layer and coal layer, and those layers are possible to generate massive landslide, so geological engineers must face the problem how to analyze the massive landslide. In this paper, on the basis of study on large-scale landslides influence on site stability evaluation of Faer Power Plant （4× 600 MW） in Guizhou Province, the practical evaluation mode on landslides influence on site stability evaluation for fossil fuel power plants is provided. The mode is to explore based on geological conditions of the landslide, and to analyze the stability of the landslide, to ascertain the feasible zone according to geotechnical conditions, and to put with some suggestions how to treat the landslide.
