Several drainage channels are usually planned in the reclamation area in order to ensure the basic water surface ratio. It is necessary to conduct deep foundation treatment before the excavation of the river due to the high water content of hydraulic fill in reclamation area. Cement mixing pile method has been widely used in the treatment of river soft foundation as a method with mature construction technology, moderate overall cost and obvious treatment effect. Taking a river in a reclamation area as an example, it is recommended to adopt the cement mixing pile method to treat the soft foundation of the river after comparing the vacuum preloading method and cement mixing pile method.
