摘　　要：吹填土由于含水量较大,在采用真空联合堆载预压处理时,塑料排水板滤膜孔径的大小直接影响处理效果,甚至影响到整个工程的成败。文中结合宁波苏宁云商物流基地的工程地质以及水文地质情况,根据吹填土含水量的不同分别采用不同孔径的排水板进行真空预压。通过该施工技术的实施,有效解决了含水量较高的吹填土工后沉降和地基承载力两方面的问题,为真空联合堆载预压处理吹填土施工探索了一种路径。As hydraulic fill has high soil moisture content, the opening size of geotextile on plastic drainage plate plays a critical factor on the vacuum preloading construction effectiveness, even the ultimate success of the engineering project. Through Investigating on the engineering geology and hydrological geology of Suning (Ningbo) Logistic Base, this paper introduces its construction method that applying vacuum preloading via different opening sizes of geotextile in accordance to the varieties of hydraulic fill water content. The application of this construction technology provides effective solutions to the foundation settlement and bearing capacity of hydraulic fill performance, and explores a new way for acuum-surcharge preloading on hydraulic fill ground construction.
