Application of the Hydraulic Compaction Method in Ground Improvements for Building Foundations
The hydraulic compaction method has been widely promoted and used in roadway engineering due to its mobility,high-frequency impact,and minimal side effects,but it is less applied in the ground improvement for the shallow foundation of buildings.A case history of a real estate construction projects is presented in this paper with the mechanism and the construc-tion process of the hydraulic compaction method.By comparing this method with the current dynamic compaction method,the advantages and disadvantages are analyzed.Experiments are conducted on the soft soil replacement based on the site conditions,and the data after compaction is studied and analyzed.The results show that the hydraulic compaction method has a strong a-daptability to the site and is more reliable comparing with the quality of replacement and the compaction.Its satisfactory com-paction effect can effectively solve the problem for the building foundations meeting the requirements of bearing capacity and de-formations after the soil replacement and compaction.The economic effect is significant.
