| Abstract: | This paper first analyzes the design index of current highway design in order to meet the requirements and provisions of the drainage, secondly, starting from a design case, analyzes the neglected design that possibly affecting the road drainage in the current combination design of horizontal curve containing vertical curve. Finally, this paper puts forward measures for improvement. |
