| 摘 要： | 真空降水结合强夯方法在港口吹填土加固工程中得到广泛应用。根据前人研究成果结合潍坊港岸滩整治软基处理工程,开展真空降水深度、土体渗透性对强夯加固效果的影响研究。结果表明:当合理布置深浅管时,即使土体渗透性变幅较大,对于真空排水及强夯的作用效果影响较小;当降水深度达3 m左右时,强夯及真空排水联合作用效果最佳。

| Abstract: | The method of vacuum dewatering united with dynamic compaction is widely used in the treatment of dredger fill subgrade.Based on the previous research and the engineering of soft soil foundation treatment on the harbor of Weifang,we study the effect of vacuum dewatering depth and soil permeability on dynamic compaction.The results show that with a reasonable layout of the tube wells of different depths,the effect is small even if the soil permeability changes greatly,and this united method works best when the dewatering depth is about 3 m. |
