Suggestions on the Design of Levee Project which Combined with Road Engineering

Abstract

According to the characteristics of levee and road combined project, the paper analyzes problems of levee road. Design speed of levee road is determined by the main function, economy and safety. The paper studies the slope and the elevation of levee crest in “Code for Design of Levee Projectâ€, and compared it with road standard. The proposal was put forward, which includes: recommended values of cross slopes is 1.5%～2.5%, minimum longitudinal gradient of crest is 0.3%, the corresponding position of the crest elevation on the cross section, the calculation of crest elevation should consider the thickness of pavement layers. Finally, an engineering example is cited, which can be used in the design of similar engineering reference argument.
