In order to increase the safety of rapid chamfer falling guttery for highway, this paper has done 3 new types of eliminating energy pool out-flow scouring experiments of rapid chamfer falling guttery for highway (the convention pool, falling water platform pool, sidestep out-flowing pool, and convention pool joining subsidiary pool). The results show that under the same flow conditions and rapid ... [Show full abstract] chamfer height, the falling platform pool outflow scouring maximal depth is the smallest among the four eliminating energy pool types, the convention pool joining subsidiary pool belongs to the second, decreasing of sidestep out-flowing pool scouring maximal depth is comparatively smaller than the convention eliminating pool, the convention pool scouring pit depth is the greatest one; the souring maximal depth decreases with increase of the falling platform pool depth, but the ordinary rush falling rapid chamfer convention pool depth increases with increase of the souring maximal depth. By considering of safety and economy of engineering, falling water platform pool and sidestep out-flowing pool can decrease the great deal of excavate soil, and increase the eliminating pool stability. The falling water platform pool, sidestep out-flowing pool, and convention pool joining subsidiary pool can decrease the preventive scouring pavement length of eliminating energy pool. Using three new types convention pool construct together, the effect of damages preventing will be improved obviously. 3 tabs, 4 figs, 6 refs.
