土工格栅在填挖交界路基处理中的应用

Application and Research of Geogrids on Cut to Fill Subgrage Treatment

试验段选用土工格栅处理填挖交界路基差异沉降问题,结果表明,土工格栅能够有效降低填挖交界路基的差异沉降;路表沉降量随着距填挖交界点距离的增大而逐渐增大;土工格栅竖向间距会对处置差异沉降的效果产生较大影响;通过试验段观测,最终建议竖向土工格栅间距宜控制在2m左右。

and the results location ; With increases ; The settlement ; The geogrids was used to deal with differential settlement of cut to fill subgrage in the test section showed that geogrids can effectively reduce the different settlement of subgade with cut to fill the increasement of the distance to the cut to fill junction point, the settlement of road surface vertical spacing of Geogrids would have a greater impact on the disposal effect of differential last, the recommendation vertical space of Geogrids should be about 2m.
