Abstract

Abstract: 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．

Key words: soil mechanics, geogrids, reinforced soils, large-sized triaxial test, shear strength

摘要： 采用大型三轴仪，对直径30cm，高60cm，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。

关键词: 土力学, 土工格栅, 加筋土, 大三轴试验, 抗剪强度
