摘　　要：针对深厚软土地基的处理,真空-堆载联合预压法是在真空预压施工的基础上进行优化后的一种地基处理工艺。研究在传统真空-堆载联合预压法的基础上,提出一种复合塑料排水板为竖向排水通道,对深厚软土地基进行处理,利用有限元分析方法对软土地基复合塑料排水板真空-堆载联合预压效果进行模拟。研究结果表明,复合塑料排水板真空-堆载联合预压与一般的现场实际处理效果相比沉降值差异在2%左右,表明采用该方法开展深厚软土地基处理的堆载高度合理、可行。Aiming at the treatment of deep soft soil foundation,the combined vacuum-surcharge preloading method is a foundation treatment technology optimized on the basis of vacuum preloading construction.On the basis of the traditional vacuum-load combined preloading method,a composite plastic drainage plate was proposed as a vertical drainage channel to treat deep soft soil foundation,and the combined preloading effect of the composite plastic drainage plate on soft soil foundation was simulated by finite element analysis method.The results showed that the difference of the settlement value of the combined vacuum and load preloading of the composite plastic drainage plate was about 2%compared with the actual treatment effect,which indicated that the loading height of deep soft soil foundation treatment by this method was reasonable and feasible.
