摘要
崩岸是由土石组成的河岸、湖岸因受水流冲刷,在重力作用下土石失去稳定沿河岸、湖岸的岸坡产生崩落、崩塌和滑坡等现象。本文针对江河崩岸险情,分析岸坡土质的类型及土层的分布、管涌现象、河道地形、水文气象环境的影响及人为因素五种原因发生的机理,从中了解控制该因素发展的关键点,分析各因素导致崩岸的过程。并根据原因及现场的施工条件,河势走向及经济条件等多重因素的综合考虑,选取适合的平顺式或垂直式整治措施,及时并有效地控制改善险情。
According to the dangerous situations, the paper studies the five impact reasons of the bank collapse such as the soil type and distribution of the bank slope, the piping, the river terrain, the hydrometeorology environment and human activities, analyzes the key point and development process of each factor. Based on the comprehensive consideration of multiple factors including the cause, the construction condition, the river regime and the economic condition, the paper chooses the suitable smooth type or vertical type treatment measures to control and remove the dangerous situations timely and effectively.
