Road subgrade slope protection and reinforcement construction technology
Expressway roadbed slope may slide due to special conditions of rock and soil mass,inadequate construction protection,vehicle load and other reasons,damage roadbed structure,threatening vehicle safety,comprehensive protection and reinforcement of roadbed slope is necessary.This paper takes a highway project as an example,through the analysis of the characteristics and causes of the roadbed slope collapse,puts forward a comprehensive roadbed slope landslide treatment scheme such as retaining wall,arch skeleton,three-dimensional mesh grass,and expounds the construction process and technical points of sheet pile wall and prestressed anchor cable,so as to effectively strengthen the highway roadbed slope and avoid the occurrence of landslide accidents.
