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.

It is adopted that anchor cable with frame beam and converse working process in the engineering.

With the development of China s transport, the issues of highway slope disease is especially outstanding, and prestressed anchor cable sash has played a more and more important role with advantages of cheap, convenient for construction, reinforcement of notable results and use of wide range.

Prestressed anchor cable sash structure which is used application far widely i.
