本文主要介绍膨胀土地基上挡土墙基底摩擦系数μ值(以下简称μ值)的现场试验方法,以及通过在不同粗糙底面和不同含水量及振动条件下μ值的试验结果。从而为膨胀土地基上设计挡土墙选用μ值时提供了有参考意义的资料。
This paper mainly introduces the field test method for the friction coefficient μ (hereinafter referred to as μ value) of the retaining wall on the expansive soil foundation, and the experimental results of μ value under different rough bottoms and different water content and vibration conditions. Therefore, it provides reference data for the selection of μ values for retaining walls designed on expansive soils.
