Abstract:
This paper is aimed to the erosion of concave bank along river for subgrade of mountainous highway, and the comprehensive protective effect of using spur dike cooperatively with apron based on indoor hydraulic model tests, theoretical analysis and verification of experimental project. It is found that: when it cannot reach the satisfied protection effect by the single use of spur dike or apron, a reasonable protection form of using spur dike cooperatively with apron can be adopted, these can make the protection effect and economy better; if the apron width is rather small, and the submerged dike length is greater than apron width, the top elevation of the spur dikes should be decreased one by one until equaling the top elevation of apron from the beginning of the upstream submerged dike; while apron width is quite large, protection effect of the apron is obvious. 1 tab, 4 figs, 13 refs.
