High and steep cut slopes due to excavation are a common sight in building high-grade throughways

the slopes’stability directly affect the safty of construction and operation of the roads in future. In the case of unstable rock slopes with potential sliding surfaces

the prestressed cable or bolt is usually used to reinforce the slopes so as to cut down engineering cost and shorten time limit for the project. In combination of the cut slope engineering works of an express way the present paper putsforward the designing method to reinforce the slope with prestressed cables

which is useful referentially for similar slope engineering works.
