| 摘 要： | 在季节性冻土地区，由于冻拔作用常使加筋土坡中土工格栅浮出地面，导致加筋作用失效，但国内关于其破坏防治的试验研究较少。通过室外冻胀试验，研究利用非冻胀性材料置换的方法对抑制土工格栅冻拔破坏的效果。对比火山灰置换与未置换的两块土工格栅的冻胀数据结果表明，置换侧的土工格栅的最终残余冻胀量较未置换侧的低50%。因此，置换方法对于抑制土工格栅的冻胀破坏效果明显，具有较强的工程实用价值

| Abstract: | In seasonally frozen soil regions,geogrids used for slope reinforcement always come out of ground because of frost heaving and thus lose effectiveness.In order to study the effectiveness of replacement with non-frozen materials in preventing frost-heaving damage to geogrids,outdoor frost heave test was conducted in the site reinforced with geogrids.The frost heaving soil in one side was replaced with volcanic ash and the other was not.Comparison between the values of frost-heave of geogrids in the two diffe... |
