Abstract Granite soils are widely distributed over the South China. With the development of highways，there have been more and more granite soil high slopes along highways. The prestressed cables frame is a common method to reinforce the granite soil high slopes. Through field test on a actual slope of Shantou—Jieyang highway，the internal force distribution and the counterforce endured of frame，the transferring rules of anchoring force in the soil，and the tensile force distribution rules of each section of cable. The results are very valuable to guide the design and construction of similar projects.
