本文阐述了鸡扒子和新滩等滑坡和崩塌形成急流险滩碍航,历史记载崩塌滑坡成滩以及史前崩塌滑坡入江成滩等实例,指出川江地区由于第四纪以来的地壳上升和河谷深切等因素,使川江两岸形成了众多崩塌和滑坡,在江中形成滩险,是河谷发育过程中的正常现象。水库蓄水后,江面开拓,水深增加,将使崩滑体对航道的影响大为减轻。并指出:为了保障目前川江航道的畅通,必须加强对崩塌、滑坡的研究、预报及处理。
This paper describes the examples of chicken planing and Xintan landslides and collapsing forming rapids, historical records of landslides into landslides and prehistoric avalanche landslides into rivers into beaches and other examples, pointing out that since the Qujiang River in the crustal rise and deep river valleys As a result, a great deal of landslides and landslides are formed on both sides of the river and the formation of beaches in the river is a normal phenomenon during the development of the river valley. After the reservoir is impounded, the river surface will open up and water depth will increase, which will greatly reduce the impact of landslide on the waterway. He pointed out: In order to ensure the smooth flow of the current waterway in the Chuanjiang River, it is necessary to strengthen the study, forecast and treatment of landslides and landslides.
