Frame lattice beam prestressed anchor cable is a new type of structure in slope management. It can be very effective in stabilizing the slope to achieve the purpose of thorough management, and at the same time, it is economical and reliable, and beautifies the environment. This paper introduces the frame lattice beam prestressing anchor cable in Yunnan Chudai highway Mazhuang pass section of the right slope management in the application of the first discussed Mazhuang pass section of the engineering geological conditions, and then put forward the design ideas, and finally introduces the construction process and quality inspection.
