| 摘 要： | 以中山市沙港公路改建工程为背景,采用旧路基外侧勘探孔参数和时间因素表示新旧路基下软基不同固结情况,针对新旧路基,采用不同的填筑顺序及加载模型模拟旧路和新拓宽段路基的不同加载历史,解决了旧路加高加宽城镇道路路基拼接软基设计计算问题,可供类似工程路基设计参考.

| Abstract: | Taking the reconstruction project of Shagang road in Zhongshan city for example,this paper analyzed the consolidation characteristics of soft foundation under the new and existing subgrade based on different data from corresponding geological exploration. The loading history of existing road and new constructed subgrade was simulated by different filling sequence and loading model. The design calculation of soft soil foundation for the project of widening and heightening existing road was solved. The results may provide a typical example for the specifications for design of highway subgrades. |
