摘要

简要介绍了水平推剪试验方法，并根据极限平衡原理，给出了水平推剪试验的计算公式。在S325侯饭线压实路堤进行了3组野外水平推剪试验，获得了粗粒土压实路堤的内摩擦角? 和凝聚力c，并分析了结果的合理性，为挡土墙优化设计提供了依据。

Abstract

Method of horizontal push-shear in-situ test is introduced briefly. And calculation formulation is presented according to limiting equilibrium theory. The shear strength parameters internal friction angle? and cohesive strength c of coarse-grained soil compacted subgrade in S325 highway are obtained by three field horizontal push-shear in-situ tests. And its rationality is evaluated. The results provide necessary base for optimum design of retaining walls.
