近年来,高速公路建设飞速发展,国、省干线公路网化改造也在加快实施。随着一大批高等级公路的相继开工建设,施工车辆给地方支线公路——主要是指公路部门列养的县道公路,造成了不同程度的、甚至是致命性的损坏。施工车辆的频繁过往致使几条公路出现大面积、不同程度的坑塘、沉陷、翻浆等损害。在此主要论述了在高速建设过程中造成支路损坏的原因,同时,还阐述了支线公路养护应采取的的具体措施。
In recent years, the rapid development of highway construction, national and provincial highway network transformation is also speeding up the implementation. With a large number of high-grade highways under construction, the construction of vehicles to the local feeder roads - mainly to the highway maintenance of county road, causing varying degrees of, or even fatal damage. The frequent passing of construction vehicles has resulted in the damage of several roads with large area, varying degrees of pit ponds, subsidence and soiling. This paper mainly discusses the causes of the branch damage in the process of high-speed construction, and at the same time, it also elaborates the concrete measures that should be taken to maintain the branch line.
