Abstract: The thick soft soils are widely deposited along the coastal areas of China and they often require ground improvement to meet the requirements of the engineering developments. This paper introduces the mechanism as well as the installation techniques of the vacuum preloading combined with surcharge method. The actual construction project indicates that this method is a cost effective method for improving the thick soft soils. The project case histories also indicate that this method is feasible to the power plant constructed on the soft soils.
