Application Of Vacuum-surcharge Preloading Treatment Of Deep Soft Soil Foundation

Vacuum-surcharge preloading is a kind of soft foundation reinforcement method base on vacuum preloading and stack preloading combined. Vacuum-surcharge preloading is fasher than vacuum preloading of soft foundation reinforcement. Vacuum-surcharge preloading is widely applied in coastal area dealing with deep mud. Vacuum-surcharge preloading as processing method of improve deep silt soil strength, widespread use in soft foundation treatment in hengqin new area, and obtained good engineering results.In this article, through zhuhai hengqin new area road soft foundation treatment project example, the Vacuum-surcharge preloading treatment, monitoring data in the construction of the deep mud and effect analysis. Mainly has carried on the following work: Vacuum-surcharge preloading method are introduced, the mechanism of the deep silt soft foundation treatment scheme selection, vacuum combined pile load preloading process of overall process, Vacuum-surcharge preloading construction quality control key points and difficult point in the process of construction, soft foundation processing monitoring data collection and analysis, analysis of soft foundation treatment effect. The engineering measurement and its analysis result have reference to the similar projects. Key Words: Vacuum stack preloading Soft ground treatment...
