| 摘 要： | 在软土层较厚时,采用真空预压不需要大量的人工堆载,节省工时,缩短预压时间。真空法所产生的负压使地基土的孔隙水加速排出,地下水位下降,可以增加施工期间的沉降量,减少路堤的工后沉降,能保证公路运营后路基的稳定性。

| Abstract: | When the soft soil stratum is deeper,vacuum combined surcharge preloading method used to treat the soft foundation can save much man-hour and shorten the preloading time.The minus stress happened by this method can quickly drain pore water from foundation soil,descend the groundwater level,add settlement during construction period,decrease settlement after construction of road foundation,which can keep the road foundation stabilization after the road runs. |
