【摘要】：绢云母片岩粗粒料作为路基填料,压实质量非常难以控制,压实度法、沉降差法等传统质量控制方法均不适用。借鉴铁路路基压实质量检测中的经验,引入动态变形模量Evd和地基系数K30指标对绢云母片岩粗粒料路基压实质量进行现场试验测试。结果表明,动态变形模量Evd和地基系数K30之间存在良好的相关性,可适用于绢云母片岩粗粒料填料压实质量控制。通过试验结果分析以及与相关资料类比,给出了绢云母片岩粗粒料压实质量控制标准。
[Abstract]:The compaction quality of sericite schist as subgrade filler is very difficult to control. The traditional quality control methods such as compaction degree method and settlement difference method are not applicable. Based on the experience of railway roadbed compaction quality testing, the dynamic deformation modulus (Evd) and foundation coefficient K30 are introduced to test the compaction quality of sericite schist roadbed. The results show that there is a good correlation between dynamic deformation modulus Evd and foundation coefficient K30, which can be used to control the compaction quality of coarse grain filler of sericite schist. Through the analysis of the test results and the comparison with the related data, the quality control standard for the compaction of sericite schist is given.
