摘要
随着我国经济水平的发展,建筑业也在不断地完善、发展,当前我国主要发展乡村山区,全力建设偏远地区的高速公路。山区的公路线形与地质条件都会影响建筑技术,并且对路基的要求很高,例如要半挖半填、深挖高填,因此就出现了路基沉降不均匀或沉降过大等一系列不稳定的情况。以实际工程为例,首先对路基差异沉降的机理进行了分析,然后重点对路基差异沉降处理措施进行了探讨,提出了有效的处理措施,保证了公路路基质量,提高了公路使用寿命。
With the development of economic level in China, the building industry is continuously been perfecting and developing. At present, the rural mountainous areas are mainly developing and the expressways in the remote regions are completely constructed. The highway alignment and geological conditions of mountainous regions will all influence the building technologies and the roadbeds are highly required, i.e. the half excavation and half filling, the deep excavation and deep filling. Therefore, there are a series of unstable situations of uneven settlement or overlarge settlement of roadbed. As an example of practical project, this paper analyzes the mechanism of roadbed settlement difference, discusses the treatment measures for the difference settlement of roadbed in detail and puts forward the effective treatment measures in order to guarantee the quality of highway roadbed and improve the service life of highway.
