摘　　要：采用大型三轴仪,对直径30 cm,高60 cm,放置两层土工格栅的加筋土复合体试件进行三轴试验。试验获得了加筋土复合体的应力-应变及其抗剪强度特性,以及含水量对加筋土复合体力学性能的影响规律。A novel triaxial instrument was employed to test the characteristic of large-sized reinforced soil sample.The sample is 30 cm in diameter,60 cm in height,and two layers of geogrid were put into it.Stress-strain relationship,shear shrength and the influence of moisture content on physical properties of reinforced soils were achieved by the test established ahead.
