摘　　要：根据某真空联合堆载预压法加固深厚层软土的试验成果,分析了地基沉降规律、控制软土地基路基工后沉降的效果,以及满足高速铁路路基工后沉降标准要求的预压时间.为真空联合堆载预压法在高速铁路深厚软土路基上的设计和应用提供了依据.Based on the in-situ test of subgrade over soft soil reinforced by vacuum combined with fill preloading, the soil settlement property, controlling effect of post-construction settlement and preloading time that satisfy the settlement standards are analysed. This will provide a basis for the design of high-speed railway subgrade over soft soil.
