摘要
本文对一软土地基上土工格栅反包直立墙面加筋土挡墙进行了相似比例模型试验,以土工格栅为筋材,以砂土为填料,分析其在顶部条形荷载作用下,墙顶沉降、墙面水平位移、墙底地基垂直应力、地基中孔隙水压力、加筋应变的变化规律。对其工作性状及其稳定性作了探讨。
A physical test was carried out to investigate the behaviour of a geogrid-reinforced soil retaining wall(RSW) with wrap-around facing on soft soil.The distributions of the settlement at top of the RSW,horizontal displacement at the RSW facing,the vertical stresses at bottom of the RSW,the access pore water pressures in the foundation,and the tensile forces were analyzed at the vertical staged strip loadings at top of the RSW.The working behaviour and the stability of the RSW were also discussed.The results can be referred to for the research,design and construction of the similar projects in the future.
