摘要
依据实际工程采用的格栅箱体加筋挡墙(CGR)新型结构,建立了基于自洽理论的筋土复合材料力学模型,并对土工格栅箱体结构的力学特性进行了深入的分析。通过分析提出了格栅箱体加筋墙墙后土压力计算模式,并在此基础上对格栅箱体加筋墙的破坏模式进行了分析。分析表明:土工格栅箱体加筋挡墙内部力学特性分布合理,能够较好地适应实际工程需要。
Based on a built cub-geogrids-reinforced earth retaining wall and self-consistent theory,a mechanical model for soil-reinforcement composite material is built up,with which,the performance of the cubgeogrids-reinforced earth retaining wall is analyzed.The model for calculating the cub-geogrides-reinforced earth wall is presented after analysis,baed on which,the failure model is analyzed.It is concluded that the cubgeogrides-reinforced wall has a good mechanical property and it can weet the demands of the civil engineering.
