加筋土挡墙中加筋与土之间的摩擦性质初探

本文通过对室内土与加筋之间的剪切试验及现场加筋拉拔试验的分析,得出土与加筋之间的剪切性质可用莫尔-库仑强度包线来表示,并建议在加筋土挡墙设计中考虑土与加筋之间的粘着力作用。本文还指明了,旨在保证加筋土结构设计的安全性、合理性及经济效果方面,用室内试验方法预报的途径。

Study on Friction Character between Soil and Reinforcement in Reinforced Earth Retaining Wall

Based on the shear tests in the laboratory and the pull-out tests in the field, it is shown that the shearing character between soil and reinforcement can be represented by the Mohr-Coulomb envelope. It is suggested that adhesive force betwween soil and reinforcement should be considered in the design of reinforced earth retaining wall. It is also pointed out that for sake of safety,reasonableness and economization of reinforced earth construction, the method of prediction based on laboratory testing shouldbeused,
