福建街面水电站地下厂房洞室稳定性评价

Stability assessment of underground powerhouse chambers of Fujian Jiemian hydropower station

福建街面水电站地下厂房洞室围岩为沉积岩,岩层平缓,地质构造发育,地下水活动较强烈,工程地质条件复杂,地下厂房稳定问题是该工程的难点。本文从地下厂房工程地质条件、施工期监测成果、运行期监测成果等方面对其洞室稳定性进行评价,得出了地下厂房洞室是稳定的结论。

The surrounding rock of underground powerhouse chambers of Fujian Jiemian hydropower station is the sedimentary rock and the rock layer is gentle.Though because of the developed geologic structures,the intense groundwater activity and the complexity of the engineering geology condition,the stability of the factory building is the special difficulty for this project.According to the engineering geology condition,the monitoring results during construction and operation,this article conclude that the cave of the factory building is steady.
