绢云母片岩粗粒料路基压实质量检测方法及其控制标准

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。

Compaction Quality Detection Methods and Control criteria of SericiteSSchistSCoarseSAggregates roadbed

As the roadbedSfiller, the compaction quality of sericiteSschistScoarseSaggregates is very difficult to control. The traditional quality control methods such as compactionSdegree method and differential settlement method are difficult to apply. By learning from the experience of the railway roadbed compaction quality detection, dynamic deformation modulus Evd and foundation coefficient K30 are introduced in the field test of sericiteSschistScoarseSaggregates roadbed compaction quality. The result shows that there is a good correlation between Evd and K30 which can be used to control the compaction quality of sericiteSschistScoarseSaggregates. SericiteSschistScoarseSaggregates compaction quality control criteria are recommended by analyzing the test results and analogizing with the related information.
