单级超高复合加筋土挡墙的原型观测

The prototype measurement of single-step compound reinforced retaining wall with super height

对一座联合应用3种加筋材料(混凝土拉筋、钢塑复合土工带拉筋以及双向土工格栅)的单级超高加筋土挡墙的拉筋拉力、填土沉降、墙面板土压力和基底压力进行了施工期间的原型观测,对拉筋拉力随填土厚度变化的规律、墙面板所受土压力、基底压力、填土沉降量变化和分布规律及其影响因素等进行了分析研究。

In this paper, the prototype measurement for the tensions of the reinforcements, the earthfill settlements, the lateral earth pressures on the face, the vertical earth pressures on the base of a singlestep compound reinforced retaining wall with super height,which reinforced by concrete block reinforcement, steelplastic compound CAT reinforcement, and bidirectional geogrid, were described. The distribution law of the reinforcement tensions and their changes with the thickness of the earthfill, and the change and distribution law and their influent factors of the lateral earth pressures on the face, the vertical earth pressures at the base, the earthfill settlements, were analyzed and discussed.
