| 摘 要： | 为探求双层立体加筋土的强度特性，通过三种布筋方式的加筋土试样进行了大量三轴试验。结果表明，在同样围压作用下，水平加筋土的强度比无筋砂土的强度有所提高;立体加筋土的强度比水平加筋土强度有所提高;立体加筋土的强度随着竖向加筋高度的增加而增加。结果还表明，不同的布筋方式对加筋土两个强度参数的贡献是不同的，单面、双面立体加筋能为土体提供较大的粘聚力，而环状立体加筋更多改善的是土体的内摩擦角。

| Abstract: | In order to make research on the strength characteristics of double-layer three-dimensional reinforced soil,a large number of triaxial tests are carried out separately on three differently reinforced soil samples.The results show that under the same surrounding pressure,the strength of horizontal reinforced soil is higher than that of unreinforced soil,and the strength of three-dimensional reinforced soil is higher than that of horizontal reinforced soil.The strength of three-dimensional reinforced soil wil... |
