摘要
利用土石方填筑体沉降观测仪进行路基沉降观测,根据路基沉降观测数据、室内试验结果、路堤在压实机械作用下的动应力分布规律、路基稳定可靠性分析结果进行路基填筑质量控制,进而选择不同的施工设备、施工工艺。该技术将路基沉降观测与路堤填筑同步进行,是一种控制路基施工质量的有效方法。
Settlement observation instrument of soil and rock filling body is used to monitor to subgrade settlement. According to subgrade settlement observation data, laboratory test results, dynamic stress distribution law under effect of subgrade compaction machinery and reliability analysis result of subgrade stability, roadbed construction quality can be controlled and different construction equipment and technologies could be determined. The technology could realize synchronous conduction of subgrade settlement observations and embankment filling, which is an effective way to control the quality of subgrade construction.
