随着我国社会经济快速的发展,先前设计建造的公路交通其中不少部分已满足不了现在交通运输的要求,需要对其进行由低向高的改扩建工程,本文就是针对此问题对公路改扩建工程中的关键技术进行分析研究,结合自身多年工作经验,希望能够对类似工程起到借鉴作用。 With the rapid social and economic development in our country, many of the previously designed and constructed road traffic can not meet the current requirements of transportation and need to be rebuilt from low to high. This article addresses the issue of highway reconstruction and expansion The key technology in the project is analyzed and studied. With many years of work experience, I hope it can be used as a reference for similar projects.
