高填路堤沉降自动化观测技术及沉降规律研究

Research on Automatic Observation Technology and Settlement Law of High-Filled Embankment Settlement

为研究高填路堤沉降规律,依托浙江景文高速公路第五合同段的高填方路段,分别采用常规水准尺和基于单点沉降计的自动化检测设备,监测了试验路段不同高程位置处的路基沉降情况,并绘制了监测期内路堤的沉降量曲线图。结果表明:路基整体沉降量与监测点高程有关;相较于常规监测手段,采用单点沉降计的自动化观测的稳定性更好,研究可为实际工程中预测路基沉降提供参考。

Based on the high fill section of the fifth contract section of Jingwen Expressway in Zhejiang Province,the settlement law of high fill embankment was studied.The conventional leveling ruler and the automatic detection equipment based on the single-point settlement gauge were used to monitor the settlement of the roadbed at different elevation positions of the test section.The settlement curve of the embankment during the monitoring period was drawn.The results show that the overall settlement of the roadbed is related to the elevation of the monitoring point;compared with conventional monitoring methods,the stability of automatic observation using a single-point sedimentation gauge is better.It can provide a reliable basis for predicting the settlement of roadbeds in actual projects.
