| 摘 要： | 结合塑料排水板加固软土路堤的工程实例,对比分析了排水板间距、堆载预压时间及堆载预压荷载对软土固结度、残余沉降的影响。总结出在工期允许的情况下,适当增加排水板间距并延长堆载时间,可有效减少工程造价并达到与较小排水板间距时相近的处理效果。在工期紧张的情况下,可通过减小排水板间距并结合超载预压,加快施工期沉降速率,满足残余沉降要求。

| Abstract: | Combining plastic dewatering plate reinforcement engineering examples of soft soil road embankment,the paper analyzed and contrasted drainage plate spacing,preloading time and the influence of preloading load on soft soil consolidation degree and the residual settlement.The research summarized that in the period permitted by time limit of project,appropriately increasing drainage plate spacing and extending heap load time can effectively reduce project cost and achieve similar effect of smaller drainage plate spacing;when the time limit is short,the residual settlement requirements can be meet by reducing drainage plate spacing and combining overload preloading to speed up settlement rate of construction. |
