摘要
水库塌岸对水库工程、库区工程产生重大影响,必须对其作出预测,定量估计塌岸速度和宽度,为移民安置、交通设施、库岸防护等工程规划设计提供依据.结合国内不同地区水库塌岸的发展规律及其主要影响因素,分析了几种常用的水库塌岸预测方法,并对其进行了分类与评价.详细论述了预测方法的适用条件及其预测要点,研究了计算参数的确定方法,探讨了坍岸预测精度的影响因素,最后给出了选择预测方法的建议.
The reservoir bank ruin will affect the security of the reservoir and the construction by-reservoir,so a prediction is important to estimate the velocity and the width of the bank ruin, which can offer evidences for the engineering programming designs about the emigration allocation, the transportation and the bank protection. Based on the systematical investigations of the development rule and the great effect factors of the bank ruin in the different area, some usual methods of predicting bank ruin are analyzed, classified and evaluated. The applicability and the main point of the prediction are expounded in detail, the approach of ascertaining the calculation parameter are studied, some influence factors of the prediction precision are explored. In the end, the suggestion how to choose prediction method is given.
