摘　　要：文章针对裕溪河堤防堤身与堤基出现的工程隐患,采用灌注桩防洪墙、削坡与锥探灌浆、填塘固基等方案进行加固处理,并运用COMSOL有限元软件对加固前、后2种工况开展渗流稳定性对比分析。加固后,堤身塑性区分布大幅减小且不连续,堤身的抗滑稳定性显著提高,加固效果明显;堤基渗流坡降满足设计与规范的要求。This article focuses on the engineering hazards that may occur in the body and foundation of the Yuxi River embankment.Reinforcement measures such as cast-in-place pile flood control walls,slope cutting and cone probing grouting,and pond filling and foundation stabilization are adopted.COMSOL finite element software is used to compare the seepage stability of the two working conditions before and after reinforcement.It is found that after reinforcement,the distribution of plastic zones in the embankment body is significantly re-duced and discontinuous,significantly improving the anti-skid stability of the embankment body,and the rein-forcement effect is obvious.The seepage gradient of the embankment foundation meets the requirements of de-sign and specifications.
