摘　　要：软弱非饱和土地基 ,常采用复合地基加固 ,但费用较高 ,采用充水预压加固可达到提高地基强度、减少工后沉降的目的 ,并可有效降低工程造价。该文简单阐述非饱和土地基充水预压的加固机理 ,结合油罐工程实例介绍充水预压荷载分级。To reinforce the soft unsaturated soil foundation,the composite foundation is usually used. But the engineering cost is high. The water-filled preload method can be used to come up to reinforce the foundation, reduce the settlement and lower the cost effectively. The paper briefly discusses the reinforced mechanism of the unsaturated soil foundation with the water-filled preload, based on an example of the oil tank engineering, introduces the load grades of the water-filled preload, the ways of settlement observation and the treatment results.
