道路旧路拓宽新旧路基变形协调综合处治技术

Coordination and Comprehensive Treatment Technology of Deformation of New and Old Roadbeds after Widening of Old Roads

公路作为现代交通运输的重要组成部分,对国家经济发展和人民生活起着至关重要的作用。然而在道路旧路拓宽过程中,常常会出现一系列由于各种原因造成的路面下部结构损坏或失效的现象,包括路基塌陷、路基沉降、路基侧滑等.严重影响了公路的使用寿命和安全性。为了确保公路的长久运行和安全,必须深入了解这些病害的成因,并采取相应的预防对策。基于此,本文结合工程实例,首先对道路旧路拓宽过程中常见的路基病害进行分析,并总结了常用的路基病害预防对策,希望能对该问题的解决起到一定帮助。

As an important part of modern transportation,highways play a vital role in national economic development and people's lives.However,in the process of widening the old road,there are often a series of damage or failure of the pavement substructure caused by various reasons,including subgrade collapse,subgrade settlement,subgrade sliding,etc.which seriously affects the service life and safety of the road.In order to ensure the long-term operation and safety of roads,it is necessary to have a deep understanding of the causes of these diseases and take appropriate preventive measures.Based on this,this paper first analyzes the common subgrade diseases in the process of road widening and summarizes the common subgrade disease prevention countermeasures,hoping to help solve the problem.
