Study on Characteristics and Prediction of Bank Collapse Caused by Water Conservancy Projects in Shanxi Province

Abstract

Bank collapse is a common engineering geological problem during the operation of water conservancy and hydropower projects. Due to different regional geological environment conditions, types and characteristics of bank collapses are various. Based on the field investigation of water conservancy projects in Shanxi Province, according to the different regional and geological environment conditions, the bank collapse caused by the water conservancy project in Shaanxi Province is divided into abrasion-induced bank collapse, erosion-induced slipping bank collapse, erosion-induced falling bank collapse and storage-induced slipping bank collapse. This paper described basic characteristics of four typical bank collapses separately, and summarized regional distribution characteristics of the four typical bank collapses; Through field investigation, we obtained the water stable slope angle, underwater stable slope angle and wave strike belt slope angle of various types of reservoir collapse banks, and used the graphical method to predict the width and development trend of different types of bank collapse and analyzed the impact of bank collapse Scope and degree of influence.
