摘　　要：随着库水位的持续上升,水库区临水岸坡可能发生塌岸,危害沿岸人员和建(构)筑安全,增加库区的淤积量,影响水库的正常运行。以陕西省引汉济渭鲸鱼沟调蓄工程的新建车村水库为例,通过野外地质勘察对库区内的岸坡类型进行分类,并选用卡丘金法和岸坡结构法相结合的方式对库区内不同岸坡类型进行塌岸预测。计算结果表明,库区两岸预测的总塌岸量为567.5万m^(3),其中入库量为230.3万m^(3),塌岸量的大小与库区两岸的岸坡类型及坡度密切相关,古滑坡和黄土直立岸坡附近更容易产生塌岸,且塌岸量大。库区内的新建车村水库坝址附近、鲸鱼沟景区、伯坊村是塌岸量最大的剖面段,对水库运行影响较大。As the water level of the reservoir continues to rise,bank collapse may occur on the waterfront slope of the reservoir area,which endangers the safety of coastal personnel and buildings(structures),increases the amount of siltation in the reservoir area,and affects the normal operation of the reservoir.The newly built Checun Reservoir of the Weijingyu Gully Regulation and Storage Project in Shaanxi Province was taken as an example.The bank slope types in the reservoir area were classified through geological surveys in the field,and the Kachukin method and the bank slope structure method were used for the analysis.Different bank slope types in the reservoir area were used to predict bank collapse.The calculation results show that the predicted total bank collapse on both sides of the reservoir area is 5.675×104 m^(3),of which 2.303×104 m^(3) has been received in the reservoir.The size of bank collapse is closely related to the type and slope of the bank slopes on both sides of the reservoir.Ancient landslides and loess stand upright.Bank collapse is more likely to occur near the bank slope,and the amount of bank collapse is large.In the reservoir area,near the dam site of the newly built Checun Reservoir,Jingyugou Scenic Area,and Bofang Village are the sections with the largest bank collapse,which have a greater impact on the operation of the reservoir.
