丘陵山谷区高速公路特殊路基段路基沉降监测研究

Research on Monitoring of Special Subgrade Settlement for Expressway in Hilly and Valley Area

丘陵山谷区特殊路基段因其具有软土、滑坡等不良地质条件,可能产生较大的沉降变形,如何有效地对丘陵山谷区高速公路特殊路基段路基进行监测,对我国高速公路建设施工具有重要意义。本文以位于丘陵山谷区的益娄高速为例,提出了一套路基沉降监测方案,并对关键技术进行详细描述,为丘陵山谷区高速公路路基沉降监测提供指导。

Due to the unfavorable geological conditions such as soft soil and landslide,the special subgrade section in hilly and valley area may have greater settlement deformation.How to effectively carry out the monitoring of the special subgrade section in hilly and valley area is of great significance to the construction of China's expressway.Taking Yi-Lou expressway located in hilly and valley area as an example,this paper puts forward a set of roadbed settlement monitoring scheme,and describes the key technologies in detail,so as to provide guidance for roadbed settlement monitoring in hilly and valley area.
