| 摘 要： | 结合一软土地基反包式土工格栅加筋黏性土挡墙现场测试，对挡墙填筑过程中原地表沉降、墙趾水平和垂直位移、墙面水平位移、挡墙内部垂直土压力和墙背水平土压力，以及筋材应变分布等进行分析，探讨其工作性状及其稳定性。分析结果表明：软土地基加筋土挡墙的破坏形式表现为外部失稳；挡墙墙面出现“鼓肚”现象，其最大水平位移位于挡墙中部墙高位置；格栅应变在距墙面0.8 H(H为挡墙的高度)处最大，设计上的0.3H法不能适用于深厚软土地基加筋土挡墙。研究成果可为今后类似工程的研究、设计与施工提供参考。

| Abstract: | A field test was conducted on a geogrid-reinforced soil wall(RSW) with wrapped face on soft ground.Such items as settlement at the original ground surface,lateral and vertical displacement at the RSW toe,lateral displacement at the RSW face,vertical earth pressure in the RSW and lateral earth pressure along the back of the RSW face and reinforcement strain were analyzed.The working behaviour and the stability of the RSW were discussed.The test results show that the failure of the RSW on soft clay exhibits e... |
