According to the requirements of this highway slope protection and local conditions,comprehensive protection measures with gravity retaining walls,shotcrete rockbolt mesh and lattice anchor rod were adopted.

The appropriate treatment with anti-slide pile and lattice anchor rod is applied and its remedial effect is better.

Qiaogong lockwall as a whole of the gravity-type structure is optimization designed to lower-lining,upper-gravity of the hybrid structure,using structure-anchor tie and drainage system to achieve stability of the lockwall,as a result of saving the project investment,speeding up the construction progress.
