摘　　要：介绍真空-堆载联合预压法机理,通过该方法在煤场地基处理中的实际应用,分析工程实际中的地表沉降,孔隙水压力,水平位移等的变化规律,从而得出了真空-堆载联合预压法具有提高加荷速率、缩短工期及减少工后沉降等优点的有益结论。The mechanism of vacuum-surcharge Preloading preloading method is introduced herein. Based on the monitoring data of the actual application in foundation treatment of coal aheap, the mechanism of the surface sttlement, settlement in layes, pore water pressure, lateral displacement, and so on, are analyzed here in, and some useful conclusions are drawn： the method mentioned herein has the following advantages： raising the rate of loading, shortening the construction period and decrease the settlement after construction as well.
