摘　　要：以苏州市工业园区桑田岛河湖相软土地基为研究背景,介绍了真空-堆载联合预压法的加固机理和桑田岛软土地基的工程地质条件,经过现场踏勘和室内土工试验的分析拟采用真空-堆载联合预压法对该软土地基进行处理。通过对真空预压试验段的地表沉降、水平位移的监测分析,对路基加固效果进行了评价,认为本试验段采用真空-堆载联合预压法处理是成功的,有效的提高了软土地基的物理力学性质及承载能力,在类似工程中推广应用是可行的。Take the lacustrine soft soil roadbed in Sangtian Island in Suzhou Industrial Park as the research background, and introduce the consolidation mechanism of vacuum and preloading method and the engineering geological conditions in this area. After site exploration and indoor geotechnical test, decided to use the municipal engineering vacuum and preloading method to reinforce the soft soil in this area. Through the process of vacuum preloading ground settlement and the horizontal displacement monitoring analysis of the roadbed reinforcement effect evaluation, drawing the conclusion that the testing section treated by vacuum and preloading method is successful, effectively improve the physical and mechanical properties of soft soil and the carrying capacity and this method can be used in the similar engineering cases later.
