完善的交通设施是社会现代化和国民经济快速发展的重要标志,随着近年来汽车行业的蓬勃发展,我国汽车量也呈增长的趋势,这使得高速公路成为了交通的主要的方式,但是由于车辆的大型化和载重物的“超载”现象,导致高速公路路面严重受损,公路质量也面临严峻考验;高速公路的特殊路基与一般公路路基不同,容易受到地形、气候或环境等多种因素的影响,导致路面损坏或者出现过陡、下陷等情况,严重威胁到公路行车安全;高质量、抗重压的特殊路基是保证高速公路特殊路段交通便利、行车安全的重要条件,对稳固路面,减少交通事故,保障行车、行人的生命安全具有重要意义。本文从高速公路特殊路基的主要危害进行分析,探讨高速公路具体施工技术。
Perfect transportation facilities are an important symbol of social modernization and the rapid development of the national economy. With the rapid development of the automobile industry in recent years, the volume of automobiles in our country also shows an increasing trend, which makes the expressway become the main mode of transportation. However, as vehicles The overloading and overloading of the heavy load cause the serious damage to the highway pavement and the severe quality of the highway. The special subgrade of expressway is different from the general roadbed and is susceptible to many kinds of topography, climate or environment As a result, the road damage or the emergence of steep, subsidence and other serious threats to the road traffic safety; high quality, anti-stress special subgrade is to ensure that the special sections of the expressway traffic convenience, driving safety of the important conditions for the stability of the road , Reduce traffic accidents, ensure traffic safety and pedestrian life safety are of great significance. This paper analyzes the main hazards of expressway special subgrade and discusses the concrete construction technology of expressway.
