Effect of Variant Water Pressure Loading on Soil Improvement by Vacuum Preloading Technique in Civil Engineering

Abstract:

The vacuum preloading technique has often applied for underwater soft foundation improvement in intertidal zones. However, in those construction activities, the variant water pressure loading has not been considered and the vacuum load was just taken as the vacuum pressure below membrane. This treatment was obviously conservative. This research aims to analyze the effect of variant water pressure on membrane on the soil improvement, and proposes the determination method of vacuum load for vacuum preloading technique in intertidal zones, serving as a valuable reference for engineering design.
