| 摘 要： | 新老路堤结合处的不均匀沉降是引起拓宽路面产生纵向裂缝的主要原因，而挡墙对拓宽路堤的不均匀沉降具有重要影响，特别是针对高路堤的拓宽问题。通过对某高速公路高填方拓宽路堤和挡墙进行现场监测，针对实时数据进行分析，研究了新老路堤和挡墙的不均匀沉降问题及相互作用，进而对路面的施工时间进行调整，避免新老路面拼接处出现纵向裂缝，为行车安全提供保证。

| Abstract: | Uneven settlement at the junction of new and old embankment is the main cause of longitudinal cracks arose on the widened pavement, and retaining wall has significant effect on this uneven settlement, which relate to hill embankment widening especially. This paper, through in-situ monitoring on high fill widened embankment of a highway and the retaining wall, analyzed the real-time data and studied the uneven settlement of and the interaction between the new and old embankment and the retaining wall, further made the construction schedule for the pavement be adapted to avoid longitudinal cracks on the pavement joints and ensure road safety. |

| Keywords: | high fill widened embankment retaining wall uneven settlement earth pressure lateral displacement |
