排桩与土钉联合支护结构的土压力分配机制

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 the-ory 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 populariza-tion and optimization of composite retaining structure of row-pile and soil nailing.
