摘　　要：随着我国经济社会一体化程度的日益完善,道路交通量亦在日益迅速增长,且重载车辆越来越多,使得部分道路路面表面功能衰减加快、路面病害不断增多,日常养护速度已跟不上道路损坏频率。但大范围的改造重建投资巨大,工期较长,并不可取。与之对比,道路的大中修就显得十分经济可行。文章主要围绕公路大中修工程设计阶段的各种前期技术调查、病害成因分析、设计原则、设计优化方案制定4个方面做重点论述。With the increasing degree of economic and social integration in China,the volume of road traffic is also growing rapidly,and there are more and more heavy-duty vehicles,which makes the deterioration of the surface function of some roads accelerated,the road surface diseases continue to increase,and the daily maintenance speed can no longer keep up with the frequency of road damage.However,the investment in large-scale renovation and reconstruction is huge and the construction period is long,which is not advisable.In contrast,major and medium-sized repairs to roads are very economically feasible.This paper mainly focuses on various preliminary technical investigations,disease cause analysis,design principles,and design optimization scheme formulation in the design stage of highway major and medium repair projects.
