摘要： 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。

Abstract: The major geology challenges in the Xiaojia River Hydropower Station in Yichang are: stability of rock mass surrounding the intake water tunnel, pressurized water pipes; high rock cut slopes at the power house etc. This paper presents the results of the geotechnical investigations. The geology and topography of the proposed site are analyzed; the stability of the intake water tunnel is evaluated throughout the rock mass classification process; the stability of the high rock cut slope is numerically analyzed. The recommendations for the design and construction are also proposed.

Key words: xiaojia river hydropower station, engineering geology, rock mass, stability of high rock cut slopes
