摘要
以高速公路软土地基处治为研究对象,分别选取采用换填法和CFG桩两种方法处治的软土地基路段,布置监测断面开展沉降监测,检验软土地基处治效果。分析监测结果,得出在路堤填筑施工期间沉降量和沉降速率较大,停工期间较小,且在沉降监测结束后路基沉降量均达到了稳定状态,说明软土地基处治达到了预期效果,路基稳定性良好。
In this paper, focusing on the treatment for highway soft soil foundation, selecting road sections treated with the replacement method and CFG pile, the monitoring section was arranged to conduct the settlement monitoring, and to verify the treatment effect. Analyzing the monitoring results, it can be concluded that the settlement volume and rate were large during the construction of the embankment filling, small during the cessation, and stable after the settlement monitoring, indicating that the soft soil foundation treatment has achieved the expected effect, and the stability of the subgrade is good.
