泥质软岩弃渣填筑路堤沉降分析

Settlement analysis of embankment filled with muddy soft rock spoil

为确定泥质软岩弃渣路堤沉降特性,结合施工案例进行监测分析、制定监测方案、布置测点对路堤施工各个阶段的沉降速率、全断面变形进行监测。分析监测结果,得出路堤底部在填筑施工阶段沉降量较大,路堤中部和上部在稳定阶段沉降量较大,但完工阶段沉降量较小,说明路基结构稳定,施工质量满足要求。

In order to determine the settlement characteristics of the muddy soft rock spoil embankment,monitoring and analysis were carried out in combination with construction cases.Develop a monitoring plan and arrange measurement points to monitor the settlement rate and full-section deformation at each stage of the embankment construction.Analyzing the monitoring results,it is concluded that the bottom of the embankment has a large settlement during the filling and construction phase,and the middle and upper part of the embankment has a large settlement during the stable phase,but the settlement during the completion phase is small,indicating that the subgrade structure is stable and the construction quality meets the requirements.
