In this paper, the causes of mass loss of throwing materials in flood control of the Yellow River were analyzed and the stress analysis model of throwing body in moving water was established with gabion as the research object. Based on the force analysis of gabion, the influence of the velocity and depth of the dangerous section to the stability of the throwing materials was studied. The results show that increasing velocity and water depth can lead to poor stability of the throwing materials in the dynamic water and increasing weight (size) of throwing materials can effectively reduce the displacement and enhance its stability. Finally, some measures are put forward, such as designing a reasonable weight throwing materials, reserving enough throwing distance or using linked gabion system to ensure the stability.
