摘要: 河工模型是解决江河治理及大型水利水电工程泥沙问题的主要手段。本文研究了河工动床模型设汁与试验过程中存在的几何变态、推移质泥沙级配选配、时间变态等问题,并提出了相应的解决途径和建议。Abstract: The physical modeling is still a main approach to solve the sedimentation problems existing in the large stream training and hydraulic projects.In this paper,some key problems,usually found in the designing of physical model and conducting physical modeling,such as geometrical distortion,time distortion,and modeling of composition of bed load are discussed,and also the feasible solutions to them are proposed in this paper.
