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。
With China’s rapid economic development and strengthening the protection of basic farmland, more and more large-scale thermal power plants are built in mountainous areas and most of them are pit-mouth power plants. Generally, they will involve the Permian Upper Longtan Formation (P2l), the main coal-bearing formation in the southwest region ). The Longtan Formation is composed of soft and slippery stratums such as coal-bearing sandstone and shale alternating with sea and land, and the unprovable engineering geological problems such as the large-scale landslide in the Hang Hau Power Plant in the Longtan Formation rock zone. Based on the study of the influence of large landslide on the demarcation of suitable site in a power plant in Guizhou Province, this paper argues that the analysis and evaluation of large landslide in the construction of mountainous mouth power plant in mountainous area can only evaluate the stability of landslide according to the identification of basic geological conditions, Suitable for the construction of the region, put forward the basic work processes proposed recommendations, large-scale thermal power plant construction in the vicinity of large landslides is feasible.
