| 摘 要： | 对目前常应用于加筋土工程中的4种典型筋材－土工带、土工格栅、土工网、土工布，分别以20％、30％、40％和60％断裂荷载作为4个拉伸荷载水平，共16组，历时10000h的长期加载蠕变试验，得出了这些筋材的蠕变特性并将试验结果进行了计算机拟合，得出4种筋材在不同拉伸荷载水平作用下的蠕变方程，对加筋土工程设计，施工具有指导作用。

| Abstract: | Creep regular of four kinds of geosynthetics is gotten, that is, geotextile strips, geotextile sheet, geogrid and geonet, under long-times load.The four load levels are 20%,30%, 40% and 60% repture load of geosynthetics.The test time is over 10 000 hours. The sixteen sets of creep test have been done, the test results were fitted by computer, and the creep test curves were obtained. The creep equation of four kinds material under the different load levels have been gotten, It is of important reference value for reinforced engineering. |
