Analysis of Highway Subgrade Slope Protection and Support Technologies

Abstract

As an important transportation hub in China the traffic volume and driving speed are important aspects of expressways. Therefore the protection requirements for roadbed side slopes are higher and it is necessary to resist rainwater erosion and other damages by protecting the side slopes. Therefore it is necessary to adopt effective technical means of subgrade protection and support. This paper mainly summarizes the characteristics of highway subgrade slope protection construction and slope protection and support technologies.
