Structural Optimization of Flood Control Screw Piles: A Review

This paper discusses the importance of research on flood control piling equipment, and lists the existing domestic flood control piling equipment. The research status of screw piles at home and abroad in recent ten years is summarized from three aspects: bearing capacity, installation torque, stress and strain of soil. This paper introduces some optimization methods closely related to screw piles, such as evolutionary algorithm, neural network, numerical simulation optimization method, and makes a comparative analysis of the optimization methods that can be adopted for the screw pile.at last Several directions which need to be further studied in the future are put forward.
