真空联合堆载预压在加固软土路基中的应用

Application of the Vacuum Stack Prepressing Method on Strengthening Mollisol Roadbeds

真空联合堆载预压方法已广泛应用于处理高等级公路的软土地基,与常规的堆载预压法对比,该方法能有效地降低工后沉降,节约工期,并能保证路基的稳定性。通过工程实例,阐述了真空联合堆载方法的加固机理,并通过对现场监测资料的分析,说明该方法用于加固软土路基所取得的良好效果。

The vacuum stack prepressing method has an extensive use in reinforcing the soft-soil foundation of a high-grade highway.Contrasting with the traditional stack prepressing method,by using the vacuum stack prepressing method it can effectively reduce settlement after the completion of the construction,shorten time limit for the project and ensure the stability of the road foundation.Taking some engineering examples,the paper presents the strengthening mechanism of the vacuum stack prepressing method.The field monitoring data show that there are better reinforcing results for the vacuum stack prepressing method in the strengthening mollisol roadbeds.
