Abstract: Based on the analysis of the relationship between the stable weight of rock ripraps and flow velocity, a discussion was made on the stability of ripraps in plain rivers and mountainous rivers. Research shows that the flow velocity in plain rivers is low, and the requirement for the weight of ripraps is less than 70kg, so there is no problem for the stability of ripraps. While for the mountainous rivers, the flow velocity is high, and the requirement of rivers for the weight of ripraps may reach several tons. The difficulty in the mining and construction of rock block with such a weight may result in an outstanding problem related to the stability. According to the research results, the flow velocity of rivers should be estimated as accurate as possible and the safety coefficient should be reasonably selected for the calculation of the weight of ripraps.
