山区公路高边坡勘察设计关键问题探讨

Discussion on Key Problems in Investigation and Design of High Slope of Mountain Road

在山区高速公路的建设中,由于对山体的切削,会产生大量的高边坡。从本质上来讲,山区就是地壳运动造成的结果,因而山区的地质构造、地形地貌比较复杂。公路路线规划过程的勘察因为在专业等方面的认识不够,对路线边坡中的某些地质现象认识出现偏差,造成在边坡的施工设计中出现加固不足和过度加固的现象,因而在施工的过程中由于加固不足出现一系列关于边坡稳定性的问题,而过度加固则造成了资源的浪费,不论如何均对工程的建设和经济的发展产生了重大的影响。而这一切的原因均是由勘察不足引起的。因此,对山区公路高边坡的勘察设计相关问题的探讨至关重要。

In the construction of mountain expressway, a large number of high slopes will be produced due to the cutting of mountains. In essence, mountain area is the result of crustal movement, so the geological structure and topography of mountain area are relatively complex.Due to the lack of professional knowledge in the survey of highway route planning process, there is a deviation in the understanding of some geological phenomena in the slope of the route, resulting in the phenomenon of insufficient reinforcement and excessive reinforcement in the construction design of the slope. Therefore, in the process of construction, there are a series of problems about slope stability, and excessive reinforcement leads to waste of resources, which has a significant impact on the construction and economic development of the project no matter how. All these reasons are caused by insufficient investigation. Therefore, it is very important to discuss the survey and design of high slope in mountainous area.
