摘　　要：为进一步研究排桩与土钉联合支护结构的土压力分配机制,在理论分析和基本假设的基础上,以剪力零点为排桩固定端,分别计算排桩的桩后土压力及各排土钉拉力,并通过迭加得到排桩复合土钉支护结构的变形曲线,为排桩复合土钉支护结构的推广应用与优化设计提供理论基础。To study further the distribution mechanism of earth pressure of composite retaining structure of row-pile and soil nailing, the position which shear force is zero is taken as fixed point, and earth pressure behind row-pile and tension of rows of soil nailing are calculated respectively based on theory analysis and basic assumption. Then , deformation curve of composite retaining structure of row-pile and soil nailing is obtained through superimposing. The paper will supply theory foundation for popularization and optimization of composite retaining structure of row-pile and soil nailing.
