软土地基承载力低、工后沉降量很大,不能满足公路路基强度性、稳定性和路面使用性能要求。本文以阿荣旗至博客图高速公路K123+000~+200段为依托,采用以冲击碾压为主的方式对软土地基进行了处理,对其压实度进行检测控制施工质量。工后沉降通过埋设沉降板对沉降进行跟踪,工后总沉降用泊松曲线法对其进行计算。结果表明,冲击压实技术用于软基地区的路基施工不仅明显改善了路基压实质量,对减小路基施工工后沉降也有明显的效果。 The bearing capacity of soft soil foundation is low and the post-construction settlement is very large, which can not meet the requirements of highway subgrade strength, stability and pavement performance. Based on the K123 + 000 ~ + 200 sections from the Arong Banner to the blog map highway, this paper treats the soft ground by means of impact rolling, and measures its compaction degree to control the construction quality. Post-construction settlement The settlement is tracked by embedding the settlement plate, and the total settlement after work is calculated by the Poisson curve method. The results show that the application of impact compaction technology to subgrade construction in soft foundation area not only significantly improves the compaction quality of subgrade, but also has obvious effect on reducing subgrade settlement after construction.
