随着经济的发展,山区高速公路的重要性日益凸显,但山区高速公路的建设具有一定难度,大型车辆运行的次数也是非常多的,所以导致了高速公路的使用寿命大大缩短,一些主要的路段也有损毁的情况发生。另外,还有一个非常重要的原因,那就是高速公路路基排水技术尚不完善,导致公路的排水能力有限,严重影响了我国山区高速公路的可持续发展,其质量也很难得到保证。因此,相关部门应该采取合理有效的改善措施,提高路基排水技术水平,提高山区高速公路的排水能力,本文首先阐述了排水设施出现问题的主要原因,随后又对山区环境对高速公路路基的影响和山区高速公路路基排水设计进行了具体分析,希望能够为相关工作人员提供一些有利参考。
With the development of economy, the importance of mountain expressways has become increasingly prominent. However, the construction of expressways in mountainous regions is somewhat more difficult and the number of large-scale vehicles is also very large. As a result, the service life of expressways is greatly shortened, and some major sections There are also damaged situations happen. In addition, there is a very important reason, that is, the expressway subgrade drainage technology is not yet perfect, resulting in limited drainage capacity of the highway, seriously affecting the sustainable development of the mountainous expressway in our country, and its quality is hard to be guaranteed. Therefore, the relevant departments should take reasonable and effective improvement measures to improve the level of subgrade drainage technology to improve the drainage capacity of mountain highway, the paper first expounds the main reasons for the problems of drainage facilities, and then on the impact of mountain environment on the highway subgrade and The expressway subgrade drainage design of mountain highway has carried on the concrete analysis, hoped that can provide the related staff some advantageous reference.
