白龙江某水电站水库区掏金洞采空区库岸稳定性分析评价

Analysis and Evaluation of Reservoir Stability of Mined-out Area of a Hydropower Station in Bailong River

白龙江某水电站水库区上游河段的水电站蓄水后,库区平台地下隐藏的古"掏金洞"采空区发生坍塌,引起地面不均匀沉陷,导致部分房屋出现拉裂,引发了次生地质灾害。因此,本文对该水电站水库区重点地段地质条件和可能存在的掏金洞采空区库岸稳定性问题进行了分析评价,为工程提供了安全依据。

After the impoundment of a hydropower station in the upper reaches of the reservoir area of a hydropower station in Bailong River, the goaf of the ＂dig out gold hole＂ hidden in the underground platform, resulting in a part of the housing cracking, causing secondary geological disasters. Therefore, this paper analyzes the geological conditions in the key areas of the reservoir area of the hydropower station and the stability of the bank stability of the mined out area, which provides a basis for the safety of the project.
