| 摘 要： | 在大型三轴仪上进行了不同含水量情况下红砂岩素土样和不同加筋方式土工格栅加筋土的三轴不固结不排水剪切试验,保证93%的压实度,从而探讨了土工格栅加筋红砂岩的力学特性及变形特性,分析了土工格栅的加筋机理,为红砂岩路基,特别是加筋红砂岩路基提供设计和施工依据。试验结果表明：素土和加筋红砂岩土样的强度均与含水量密切相关。其抗剪强度指标随含水量的变化规律大致相同。

| Abstract: | On the large-scale triaxial test equipment,the triaxial unconsolidated undrained tests of geogrid reinforced earth and non-reinforced soil at different water contents and different reinforcing methods were carried out,when the degree of compaction of soil sample was 93%.In this paper,characteristic of strength and deformation of geogrid reinforced red sandstone soil were studied,and reinforcement mechanism of geogrids was analyzed.The scientific basis for design and construction of red sandstone roadbed,esp... |
