【摘要】：西南水电开发逐步进入发电运行期,大型水电站蓄水后水库岸坡在库水位升降、降雨等因素影响下,大多会导致库岸再造、崩塌、岩体蠕变、古滑坡复活、基岩变形加剧等多种地质灾害的发生,给库区周边人民生命财产和工程运行安全形成潜在安全风险。基于溪洛渡水电站水库影响区GNSS监测成果,构建了水库影响区快速监测分析预警体系,并利用该体系对水库影响区安全稳定进行分析评价,以保证水库影响区的围岩稳定和运行安全。通过建立的评价体系流程应用于溪洛渡水库影响区的预警评价中,取得了不错的效果,可进行推广应用。
[Abstract]:The hydropower development in Southwest China has gradually entered the power generation period. After the storage of the water level of the large hydropower station, the reservoir water level rises and falls, and the rainfall and other factors affect most of the geological disasters, such as the reengineering, collapse, rock mass creep, the resurrection of the ancient landslides and the aggravation of the deformation of the bedrock, which form the safety of the people's life and property around the reservoir area and the operation of the engineering. The potential safety risk. Based on the GNSS monitoring results of the reservoir affected area of Xiluodu Hydropower Station, a rapid monitoring and analysis and early warning system for the reservoir impact area is constructed, and the system is used to analyze and evaluate the safety and stability of the reservoir affected area, so as to ensure the stability and operation safety of the surrounding rock in the reservoir affected area. The early warning evaluation of Luodu reservoir affected area has achieved good results and can be popularized and applied.
