Taking treatment engineering of high slope s faults in Huangdao arterial highway as an example,this paper analyzes geotechnical stability and failure mode of slope,introduces the treatment measures of high slope,and discusses the construction technology flexible slope protection and slope protection by pre-stressed anchor cable frame,which to offer a reference for relevant project.

Analysing the character of internal forces of anchor cable frame by Winkler model,and verifying it by field test,a calculation method is put forward based on elastic foundation beam.

Combining with the engineering practice of Quan-San highway SMA10 contract section YK201+830～YK201+980 slope collapsed treatment,the slope strengthening treatment construction technologies such as prestress anchor cable frame and anti-slide pile were mainly introduced,and the surface and deep hole displacement of slope were observed.

Analyse work characteristic and construction technics of anchor frame.

The revetment with anchor bolt frame is a new type of slope protection and strengthening measure applied for expansive soil side slope.
