社会经济的不断发展,使得区域间的交流日益频繁,同时也对道路交通的通行能力提出了更高的要求,使得改扩建公路工程项目显著增多。就公路改扩建施工而言,主要包括单侧或者双侧拓宽两种形式。具体建设过程中对于工程设计要求较高,若控制不到位,极为可能导致新老路基间出现较大沉降现象,严重影响到改扩建工程的整体质量水平。因此文章就公路改扩建中路基沉降处理措施展开相关探讨,以供参考。
The continuous development of social economy has made the exchanges between regions more and more frequent. At the same time, it has also put forward higher requirements on the capacity of road traffic, which has led to a marked increase in the number of road projects under reconstruction and expansion. In terms of highway reconstruction and expansion construction, mainly including one or both sides to broaden the two forms. In the concrete construction process, the engineering design requirements are high. If the control is not in place, it is very likely to cause a large settlement between the old and new road bases, seriously affecting the overall quality of the reconstruction and expansion project. Therefore, the paper discusses the subsidence treatment measures of highway subgrade expansion for reference.
