| 摘 要： | 以玻璃纤维和土工布作为加筋材料,对比研究红土在三种不同排水条件下加筋前后的抗剪强度特性.三轴试验结果表明:红土在完全固结排水条件下剪切,加筋能提高其抗剪强度,加筋层数越多,强度提高越大;在固结不排水条件下剪切,当加筋层数较少时,加筋后其抗剪强度反而比不加筋时降低,但随着加筋间距的减小,抗剪强度逐渐增大;而在完全不固结不排水条件下剪切,加筋降低其抗剪强度,且抗剪强度随围压的增大而减小.说明红土在不排水条件下加筋应慎重考虑.

| Abstract: | In order to understand the shear properties of reinforced laterite,fiber and geotextile are used as materials to reinforce laterite in the tests under three drainage conditions.The result is as follows.When consolidated and drained,the reinforced laterite has higher shear strengths;when consolidated but un-drained,it has lower shear strengths compared with the one un-reinforced,but whose strength is increasing if more materials are added;when unconsolidated and un-drained,it definitely demonstrates lower shear strengths even though the confining compress is increasing.So a careful thought should be given to reinforcing laterite under un-drained conditions. |
