摘　　要：本试验性工程采用新型真空预压法,将水平向排水通道设置为排水板与滤管的直接连接,以及增铺地表排水板和三维土工格栅,从而缩短真空压力传递路径,提高能源利用率,以及节约成本,并达到地基处理的目的。通过对新型真空预压法软基处理的监测与效果检验,表明各项指标均满足设计要求。New vacuum preloading method is applied in this experimental project. The horizontal draining passage adopts the direct connection between drain boards and filters. Meanwhile, the surface drain boards and 3D geotechnical grids are added in order to shorten the transmission path of vacuum pressure, improve energy utilization, decrease cost and satisfy the requirement for foundation treatment. The monitoring work effect test are carded out for the soft base treatment by using new vacuum preloading method, which shows that all relevant indices meet the design requirements.
