基于浪蚀龛和土体临界高度的修正的卡丘金法及其工程应用
Modified Kachugin method based on wave cut notch and critical height of soil and its engineering application
摘要
Abstract
Research on rebuilding prediction of bank slope during the operation of reservoir is one of the important and hot topics in engineering geology field. In light of defects of Kachugin method applied to bank collapse prediction on soil bank slope including using semi-empirical, semi-quantitative model, simplifying the influence of hydrogeological conditions and ignoring the effect of wave erosion on bottom of bank slope, a modified Kachugin method based on wave cut notch and critical height of soil is put forward. Estimation method for stability time limit of soil bank slope rebuilding is established. Limit equilibrium method and Kachugin method and the bank slope rebuilding prediction method are used in bank collapse prediction of Baima harbor bank slope at Fengjie in the Three Gorges Reservoir. The calculation results show that the result of modified Kachugin method is small than one by other two kinds of prediction methods;and the deviation is less than 8.05m . Based on reservoir bank geological survey at present, it is consistent with the truth one. Research results have important positive significance for land resources development and utilization in bank area and prevention and mitigation of reservoir bank.关键词
