分层片石摊铺填筑过湿土路基试验研究

针对过湿土因天然含水量高而不能直接用于填筑路基的问题，提出过湿土分层片石摊铺处治技术，并对施工方法和处治效果进行现场填筑试验研究。采用沉降观测和探坑检测2种方法对填筑施工质量进行检测，测试结果表明，当碾压10遍后，沉降趋于稳定，过湿土部分嵌入片石层，两者结合紧密，路基整体填筑质量密实。

Experimental Research on Laminated Rubbles Paved and Filled Over-wet Soil Roadbed

In allusion to the problem that over-wet soil cannot directly used to fill roadbed for high water content, this paper proposes treatment technology of pavement of laminated rubbles on over-wet soil and performs on- site filling experimental research on construction methods and treatment effects. Two methods, namely settlement observation and pit test are adopted to detect filling construction quality, after rolling compaction for 10 times, the settlement is tending to stabilize, part of over-wet soil embeds into rubble layer, both are closely united, and the integral filling quality of roadbed is compact.
