在高速公路施工过程中,水分与路基路面的强度及稳定性的关系较为密切。由于路基路面中有多种病害存在,且病害产生的因素也各不相同,而水分的作用是各因素中的关键。所以,在路基路面的设计、施工及养护过程中,必须对路基路面的排水设施进行有效的关注,进一步将水分对高速公路造成的影响降低。本文主要从高速公路中路基路面的排水设计着手,根据排水设计的理念及方法进行了详细的阐述。
During the highway construction, the relationship between moisture and the strength and stability of subgrade and pavement is relatively close. As there are many kinds of disease in subgrade and pavement, and the factors that cause disease are different, and the function of water is the key of all factors. Therefore, during the design, construction and maintenance of subgrade and pavement, effective attention must be paid to the drainage facilities on subgrade and pavements to further reduce the impact of water on the expressway. This paper mainly starts with the drainage design of highway subgrade and pavement, and gives a detailed description according to the concept and method of drainage design.
