The dynamic-static combined drainage consolidation technology is an effective method for rapid reinforcement of deep soft soil foundations and control of post-construction settlement.This paper systematically reviews the latest progress in theories and processes of the technology,reveals the internal synergistic mechanism of static drainage system and dynamic loading,discusses the mainstream processes and applicability of the combined technology,and analyzes the key control parameters for technical synergy.Results show that vacuum preloading provides favorable conditions for dynamic reinforcement of soft soil.Dynamic impact induces excess pore water pressure and forms new drainage micro channels,which can greatly accelerate consolidation and generate a crust layer with a certain thickness.The key to dynamic-static combined drainage consolidation lies in parameter matching,including drainage conditions,properties of overlying strata,dynamic loading time,dynamic reinforcement modes,process parameters and time intervals.Engineering cases prove that compared with conventional vacuum preloading,this combined technology can raise bearing capacity by 1.5 times,and cut construction period and cost by 30%-50% or more.Finally,this paper explores the technical challenges and development prospects of the cutting-edge technique of synchronous vacuum preloading combined with dynamic compaction/vibro-compaction,which can provide a reference for the further optimization and innovation of this technology.
