摘要
在崇明地区潮湿路基项目基础上,针对高地下水位区域的道路路基稳定性问题开展路基填料配比改良试验研究。通过在试验段区域采用2种不同掺量的水泥土填料,并基于场外试验段施工,进行同等条件、相同工况下,潮湿路基水泥土回弹模量、压实度、弯沉值等的试验检测。检测结果满足设计要求,达到了预期效果,为后续路基实施提供了依据。
On the basis of the project of wet subgrade in Chongming area,the experimental study of improved proportion of subgrade filler is carried out for the stability of road subgrade in the area with high groundwater level.Based on the construction of the off-site test section,two different cement soil fillers were used in the test section to test the modulus of resilience,degree of compaction and deflection value of cement soil in wet subgrade under the same conditions and conditions.The test results meet the design requirements,achieve the expected results,and provide the basis for the subsequent implementation of subgrade.
