摘　　要：首先介绍了真空堆载联合预压法的加固机理,然后结合高速公路软基处理中真空堆载联合预压法的应用,分析了对该类工程的加固效果,认为真空堆载联合预压法施工工艺成熟、能增加地基稳定性、缩短施工工期,可作为高速公路软基处理的一种手段进一步推广。Reinforcement mechanisms of vacuum combined surcharge preloading method is introduced, meanwhile, an introduction is given to the application of vacuum combined surcharge preloading method in soft subgrade improvement of express highway. The effect of reinforcement is analysised, which indicates that vacuum combined surcharge preloading method is a ripe technology, which can improve foundation stability and reduce construction period. The method may be used as a reference for the construction of similar projects in the area.
