| 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 ve... |
