摘要
通过对长余高速公路实验路段的观测数据进行分析,发现地下水活动对土基沉降影响显著,在定量与定性分析的基础上,提出在地下水显著下落的时段增强碾压,加速桥头土基沉降,进而减少桥头工后差异沉降的施工方法,该方法对减少桥头工后差异沉降具有重要的现实意义。
Through analysis the data of the Changyu highway, it found that groundwater have more contribution to the soft roadbed＇s settlement. Based on qualitative analysis, the construction method for decreasing the settlement by improving the rolling of the bridge head embankment and accelerate the settlement when the groundwater level is lower is got and the method has important meanings for decreasing the soft roadbed＇s settlement.
