设计速度为60km/h时，凸形竖曲线最小半径一般值为1350m 、极限

设计速度为60km/h时，凸形竖曲线最小半径一般值为1350m 、极限值为900m ；凹形竖曲线最小半径一般值为1050m、极限值为700m。

結果 (英文) 1:

Design speed: 60km/h time, convex vertical curve minimum radius value is 1350m, the ultimate value of 900m; concave vertical curve minimum radius value is 1050m, the ultimate value of 700m.

結果 (英文) 2:

Design speed of 60km / h, the minimum radius of convex vertical curve is generally 1350m, limit is 900m; the minimum radius concave vertical curve is generally 1050m, the limit for the 700m.

結果 (英文) 3:

When the design speed is 60km/h, the minimum radius of the convex vertical curve is 1350m, the limit value is 900m, the minimum radius of the concave vertical curve is 1050m, and the limit value is 700m.
