摘要
在现场测试、室内土工试验及工后沉降监测的基础上,结合理论和数值分析,对强夯加固拓宽路基及降低新老路基差异沉降的效果进行研究,得到强夯后路基平均下沉0.245 m,地基土固结度达到57%,其新老路基沉降量均满足规范要求。
Based on field test, laboratory soil test and post-construction settlement monitoring and combined with theoretical and numerical analysis, the effect of dynamic compaction on widened subgrade reinforcement and differential settlement reduction is studied. As a result, the subgrade reinforced by dynamic compaction and settled by 0. 245 m on an average and the consolidation degree of the foundation soil reached 57 %. Therefore, the settlement of both the new and old subgrade has met the specification.
