宜昌肖家河水电站的主要工程地质问题包括引水隧洞工程区围岩稳定性,压力管道——厂房区高边坡稳定性等。在工程勘察的基础上对工程区的地形地貌、地质结构进行了分析,通过围岩分类对隧洞的岩体稳定性进行分析与评价,对堆积体边坡进行了模拟计算分析,最终对主要的工程地质问题进行了分析评价并给出相关建议。
The main engineering geological problems of the Xiajiahe Hydropower Station in Yichang include the stability of surrounding rock in the diversion tunnel project area and the stability of high pressure slopes in the powerhouse area. Based on the engineering survey, the topography and geology structure of the project area are analyzed. The rock mass stability of the tunnel is analyzed and evaluated by surrounding rock classification. The slope of the pile body is simulated and analyzed. Finally, The engineering geological problems are analyzed and evaluated and relevant suggestions are given.
