摘　　要：某工程原边坡受红线限制,削坡空间有限,导致内侧形成了较高陡的边坡,且经过3年多的运行,受雨水的冲刷,该高边坡段落局部出现了崩塌,需要进行治理。工程采用钢管桩+混凝土支撑梁方案进行治理,并对正常蓄水工况、设计洪水位降落工况和正常蓄水遭遇地震工况3种工况进行有限元分析。结果显示,均满足稳定性要求,治理方案有效。The original slope of a project is limited by the red line and the space for cutting slope is limited,which leads to the formation of a high and steep slope inside.After more than three years of operation,the high slope section partially collapsed due to the erosion of rain,which needs to be treated.This project adopts the steel pipe pile+concrete support beam scheme for treatment,and carries out finite element analysis on the normal water storage condition,the design flood level fall condition and the normal water storage earthquake condition.The results show that the stability requirements are met and the treatment scheme is effective.
