Abstract Design optimization of construction dewatering has important values in protecting the surrounding environment and reducing the engineering cost. The existing dewatering design methods are mostly based on the optimization of pumping rate needed to maintain a stable water level, while the drop and rise of water level are not considered in the estimation of pumping rate and dewatering time. The dynamics process of construction dewatering is taken into account in this article. The method for calculating the total water yield and dewatering time from the initial groundwater level to the target water level is established. Then, the design optimization of well group dewatering is provided with the consideration of total water yield and dewatering time in dynamic dewatering process. Finally, the method for the calculation of total water yield and dewatering time when dewatering regions change is derived. The proposed method can realize design optimization and dynamic control of dewatering as the dewatering regions and water level changes in construction. The reliability of this method is verified in on-site engineering applications.
