摘　　要：广东韩江梅江河堤防由于堤基处理简单、筑堤土料差等原因出现了堤身渗漏、坡脚崩岸、裂缝塌坡等问题,堤身安全稳定性不足,影响了堤防正常的防洪排涝的功能,急需加固除险治理。在提出了一套加高培厚前后坡,堤顶水泥硬化,加设防浪墙的综合加固方案后,使用“AutoBANK-水工结构有限元分析系统”软件,对典型断面进行了渗透稳定性分析,用圆弧法进行了防滑稳定计算,堤身稳定性满足要求。Due to the simple treatment of embankment foundation and poor soil material for embankment construction,problems such as seepage of embankment body,bank collapse at the foot of slope,cracks and slopes have appeared in the embankment of Meijiang River.Insufficient safety and stability of the embankment affects the normal functions of flood control and drainage of the embankment,so reinforcement and risk removal are urgently required.In this paper,a comprehensive reinforcing scheme is proposed,which includes increasing the thickness of front and rear slope,hardening of cement on the top of embankment and adding wave break wall.Meanwhile,the penetration stability of typical section is analyzed by using AutoBANK software.The stability calculation of anti-slip is carried out by using the circular arc method,and the stability of embankment body meets the requirements.
