加筋土铁路路肩挡土墙受力及变形的研究

A STUDY ON STRENGTH AND DEFORMATION OF REINFORCED EARTH RETAINING WALL AT ROADBED SHOULDER

根据模型及试点工程原型试验对加筋土挡土墙各组成部分的受力及变形进行了分析，阐述了墙面侧压力、竖向应力、拉筋拉应力分布、墙面位移及拉筋似摩擦系数的有关规律，并对列车荷载作用的影响进行了分析和讨论。提供的试验资料对今后加筋土挡土墙的研究与设计具有参考价值。

Strength and deformation of all component parts of reinforced earth retaining wall at roadbed shoulder are analyzed on the basis of full-scale test and model test. Some relevant requlavities of lateral pressures,vertical stvesses,tension stress distribution on tensile bars,lateral displacement of the wall and coefficient of quasi-friction are described. And train load influences are also analyzed and discussed in this article. The test results are of great value for future studies and designs of reinforced earth retaining wall.
