摘　　要：对某堤防失事区域典型断面进行稳定性分析,对土体参数进行反演,并基于反演参数对处理措施进行评价。结果表明,采用搅拌桩处置方案时,在目前单桩强度参数的基础上,提高单桩强度参数粘聚力c至250 kPa或者增加搅拌桩置换率至20%均可满足规范对于安全系数的要求,应结合工程造价等因素综合选取处理方案。The stability analysis of the typical section of a dike accident area is carried out,the soil parameters are inversed,and the treatment measures are evaluated based on the inversion parameters.The results show that when adopting the treatment scheme of mixing pile,on the basis of the current strength parameters of single pile,increasing the cohesion of single pile strength parameter c to 250 kPa or increasing the replacement rate of mixing pile to 20%can meet the safety factor requirements of the code,and the treatment scheme should be selected comprehensively according to the factors such as project cost.
