真空—堆载预压法在高速公路软基处理中的应用

Application of vacuum-surcharge preloading method in soft highway foundation treatment

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。

Combining with the application of vacuum-surcharge preloading method in coastal highway soft foundation reinforcing treatment, the paper analyzes its reinforcement mechanism and effects, and compares it to other methods based on site detection data. The analysis results show that the method speeds up the soft foundation consolidation settlement speed and meets the highway soft foundation stability demand, which has provided some guidance for similar foundation treatment issue.
