Engineering Geological Evaluation of Wanjia Medium-sized Reservoir Area in Ningguo City
Taking Wanjia medium-sized reservoir area in Ningguo City as the research object,this paper analyzes the basic geological conditions of the reservoir area and further evaluates the main engineering geological problems existing in the reservoir area.The results show that the reservoir area is located in a low mountain,eroded shallow hilly terrain,with well-developed mountain slopes and gullies along both sides of the river,and a fragmented terrain.The lithology of the reservoir area consists of sedimentary rocks from the Upper Sinian,Cambrian,and Lower Ordovician,as well as loose deposits from the Quaternary.There are no regional faults passing through the reservoir area,and there are 6 relatively large faults.On this basis,the stability of the reservoir bank slope,the possibility of permanent leakage after water storage,and the possibility of induced earthquakes by the reservoir were further analyzed through lithology,structure,and hydrogeological conditions,providing a detailed basis for the construction of the reservoir and laying a foundation for guarantee.
