| 摘 要： | 利用室内平面应变压缩破坏试验,对加筋砂土中土工格栅配置形状及其刚性的加筋加固效果进行了考察与分析.结果表明:增加土工格栅加筋材与砂土之间的接触面积,可以明显地提高加筋砂土的压缩强度,它所带来的加筋加固效果要远大于通过提高加筋材用量或增加刚性所带来的加筋加固效果.在材料使用量一定的情况下,合理地提高土工格栅的面内配置密度,可以有效地提高加筋土的压缩强度,加筋加固效果明显. |

| Abstract: | By conducting a series of plane strain compression tests on reinforced sand,the reinforcing effects of geo-grid reinforcement shape and rigidity were studied.It was found that increasing the contact area between geogrid reinforcement and sand could obviously pull up the compression strength of reinforced sand and the reinforcing effect of reinforcement covering area was much better than that of reinforcement rigidity for the geogrid reinforcement in the reinforced sand,and it is a reasonable reinforcing method to properly increase the reinforcement covering ratio under the same reinforcement consumption. |
| Keywords: | reinforced sand plane strain compression geogrid shape rigidity |
