摘要

为研究双绞合六边形钢丝网加筋土挡墙的受力、变形特性，对潭衡（湘潭－衡阳）西线高速公路K124+340断面组合式面板双绞合六边形钢丝网加筋土挡墙进行了现场试验，测试了竖向土压力、水平土压力、筋材拉应变分布规律和格宾箱变形规律。结果表明：在筋材长度方向上，竖向土压力在挡墙下部呈双峰型分布，而在上部呈单峰形分布；墙背水平土压力沿墙高呈非线性分布，最大值发生在墙高约1.5 m处，实测水平土压力小于主动压力；筋材应变在筋长方向上呈非线性分布，各层筋材的应变分布模式不相同；筋材的变形主要发生在施工期，格宾箱的变形呈鼓胀式

Abstract

In order to study the structural characteristics of earth retaining wall reinforced with double twisted hexagonal steel wire mesh

a field experiment is conducted on a composite panel earth retaining wall reinforced with which on the site of K124+340 of Xiangtan-Hengyang West Line Expressway

its vertical earth pressure

horizontal earth pressure

tensile strain distribution of geosynthetics and gabion deformation law are tested. The results show that: along the length of the reinforcement

the distribution of vertical earth pressure is bimodal-shaped distribution in the lower part of the retaining wall while a single peak-shaped distribution in the upper part; the horizontal earth pressure along the wall is nonlinear distribution

the tested maximum occurs at the height about 1.5 m and it is less than active earth pressure; the tensile strain of reinforcement distributed in a nonlinear form along the length; and different layers have a different forms

the deformation of reinforcement takes place in the construction period mainly; the deformation of gabion showed a bulging form.
