| 摘 要： | 为探索新吹填粉质粘性土的经济合理的加固方法,在烟台港地区进行了袋装砂井加强夯法和单纯强夯法的对比试验。结果表明,单纯强夯法加固新吹填的埋深较浅的粉质粘性土地基效果不理想,在地基中打入袋装砂井后,由于袋装砂井起到加速排水固结和限制地基土产生侧向位移的作用,再辅以强夯法加固新吹填粉质粘性土地基,可以取得更好的效果。

| Abstract: | In order to find out an economic and reasonable consolidation method to improve new reclaimed silty clayey soils,a comparative test is carried out using sand wicks in combination with dynamic consolidation and single dynamic consolidation method respectively in the area of Yantai,Shandong Province,China.The results show that the effect is not satisfied using single dynamic consolidation method to improve new reclaimed shallow layer silty clayey soil foundation,while using sand wicks in combination with dynamic consolidation,an excellent result can be obtained due to the acceleration of drainage and consolidation and the control of lateral displacement of foundation soils. |
