本文主要介绍在西藏墨脱公路区域气候、地形、地质极其特殊的项目建设条件下,通过从理论、工程等各方面的论证,合理地采用路线平、纵面极限指标,使得工程具备一定的可靠性、可行性,从而将论证思路引发运用于类似本项目的其他低等级公路建设中去。 This article mainly introduces the feasibility of using the horizontal and vertical limit indicators of the route in the project construction conditions of the special climate, topography and geology in Tibet Medog Highway area through the demonstration of theory and engineering, and makes the project have certain reliability Sexuality and feasibility, so as to lead the argument to be used in other low-grade highway construction like this project.
