结合真空—堆载联合预压法在某滨海高速公路软土地基加固处理中的应用,对这种新型方法的加固机理及效果进行了分析,并通过一些现场观测资料与其他方法进行了对比。通过分析表明,该方法加快了软基的固结沉降速度,满足了高速公路对软基稳定性的要求,对处理类似条件下的地基问题提供了借鉴。 Combined with the application of vacuum - surcharge combined preloading method in the consolidation of soft soil foundation of a coastal expressway, the reinforcement mechanism and effect of this new method are analyzed and compared with other methods through some field observation data. The analysis shows that this method accelerates the consolidation settlement rate of soft foundation, meets the requirements of expressway for the stability of soft foundation and provides references for dealing with the foundation problems under similar conditions.
