Abstract: Because Zaijiuting is an important landscape in Le Shan Grand Buddha, the world natural and cultural heritage, its dangerous rock reinforcement engineering is different with other general slope protection engineering. Stability of Zaijiuting dangerous rock was increased, by the design of Zaijiuting dangerous rock connected with behind mountain rock, according to the mountain and landform. At the same time, natural and original feature of rock face was kept, coordination of reinforcement engineering with surrounding landscape was firmed, thus influence of sight sense by the engineering structure was reduced to the list.
