摘要
本文从加筋土挡土墙的破坏形式和破坏机理出发,考虑加筋土挡土墙施工阶段和正常使用阶段作用状态,通过分析不同挡土墙墙高的设计加筋长度,得到了两种作用状态下不同条件的设计加筋长度规律。由此得知,在施工阶段,加筋土挡土墙的设计加筋长度必须按照施工工况进行内部稳定性验算,在正常使用阶段,可只按照设计墙高进行内部稳定性验算;在加筋土挡土墙内部滑移稳定性设计时,同时考虑施工阶段和正常使用阶段两种作用状态是合理、必要的。
Based on the failure modes and failure mechanism of reinforced earth retaining wall,this paper analyzed the reinforcement length of different high retaining wall,it is found that some law of reinforcement length under different conditions during the construction and normal service stages. The conclusions are drawn as follows： 1. Internal stability should be analyzed for every condition on constructing phase of reinforced earth retaining wall,and the final reinforcement length of each layer obtained from different conditions in the construction phase. 2. Internal stability should be only analyzed for the design height of reinforced earth retaining wall in normal use stage; It is reasonable and necessary that the reinforcement length must be calculated by two stage design method recommended in this paper.
