Construction Key Points of the Ultra-soft Soil Consolidation by Vacuum Combined Surcharge Preloading Method

Vacuum combined surcharge preloading method can gain higher bearing capacity than the traditional vacuum preloading method.But opposite to say,its technology is difficult to construct,this paper discusses the construction key points and possible arrangements of every process.The vacuum combined surcharge preloading method needs to consider the requirements of the technology and the location of the facilities in the field,also the points for attention during the surcharge process.Taking every related process during surcharge preloading into consideration,it provides convenient conditions for the collaboration construction of many large-scale construction machineries in a short time.Good effects of the foundation consolidation are earned and provide guarantees for the following construction of fields.
