一种新型楔形拉筋加筋土挡墙的原型观测

对南昆铁路广西田林站内一座新型钢筋混凝土楔形拉筋加筋土挡墙的拉筋拉力、填土沉降、墙面板土压力、面板水平位移以及施加列车荷载后的变化进行了原型观测。分析研究了拉筋拉力随填土厚度的增大而变化及其分布规律 ,墙面板土压力和水平位移、填土沉降量的时间变化和分布规律及其影响因素。

The prototype measurement of retaining wall reinforced by a new type of wedgy tied reinforcement

In this paper, the prototype measurement for the tensions of the reinforcements, the earthfill settlements, the lateral earth pressures on the facing, the displacements of the facing and their changes under the train load of a retaining wall, which located at the Tianlin station,Guangxi province, on Nankun railway and reinforced by a new type of reinforcing bar and wedgy concrete block reinforcement, were described. The tension distribution law of the tied reinforcement and their changes with earth filling, and the change and distribution law and their influence factors of the lateral earth pressures on the facing, the horizontal displacements and the earthfill settlements were analyzed and studied.
