加筋土挡土墙受力及变形分析

本文论述了加筋土挡土墙的受力与变形规律并着重指出了作用于墙面板上的侧压力大大小于静止土压力而接近主动土压力;侧压力呈曲线分布;侧压力随着荷载增加而增加,且与荷载增加数值成正比关系;加筋土的拉筋拉力呈曲线分布;各层拉筋最大拉力位置联线位于0.3倍墙高附近,本文还指出最大拉力的拉筋位于墙高一半以上的一定部位,而并非为最底层拉筋。

Analysis of Strength and Deformation of Reinforced Earth Retaining Wall

This paper expounds strength and deformation of reinforced earth retainning wall and emphatically points out the following regularity:the lateral pressure on the wall is obviously smaller than earth pressure at rest but it approaches active earth pres- sure;lateral pressure appears curved distribution;the lateral pressure is getting increased with load and becomes larger in direct proprotion to the increase of load;the distribution of tension of tensile bar of reinforeed earth is curved;the location line of the largerst tensile force on each reinforced bar is situated near 0.3H(H-height of retainning wall). And the paper points out that the tensile bar with the largerst tension is situated about half of the height of retain- ning wall but not at the lowest part.
