图解法和卡丘金法库岸塌岸分析对比研究

摘要

分析库水冲蚀、浪蚀作用下库岸的塌岸类型及其主要因素,对其主要破坏方式进行预测,利用图解法和卡丘金法分别对该库岸的20个剖面塌岸宽度进行计算情况.计算结果表明,通过卡丘金法计算得到的库岸塌岸宽度与实际情况相差很大,而图解法的计算结果符合实际情况.对于实际工程,可以灵活分析和运用.%This paper analyzes the main types and factors of bank collapse under the effect on water erosion and corrosion,forecasts the main way of destruction,calculates and analyzes the width of 20 sections of the bank by using the Graph method and Kachugin method respectively.The results show that the width of bank collapse was calculated by using Kachugin method has a great difference with reality,however,the results by graph method conforms with reality.So it can be flexibly analyzed and applied for practice engineering.
