摘　　要：以厦门某浸水重力式挡土墙加固为例,为解决现状护岸挡土墙已沉降、倾斜的问题,分析了其失稳原因,分别就挡土墙前、后不同部位的加固方案进行了比选,创新性地选用了墙前块石反压加插打松木桩+墙身注浆+墙后水泥土墙支挡的组合结构行式,有效改善了墙身稳定性,解决了挡土墙沉降及位移问题。Taking the reinforcement of a flooded gravity retaining wall in Xiamen as an example,in order to solve the problem of settlement and inclination of the existing bank protection retaining wall,the reasons for its instability were analyzed,and the reinforcement schemes for different parts of the front and rear of the retaining wall were carried out respectively.For the comparison and selection,innovatively selected the combined structure type of block stone back pressure in front of the wall plus insertion and pine piles+wall grouting+cement-soil wall support behind the wall,which effectively improved the stability of the wall and solved the problem of retaining so,wall settlement and displacement problems.
