Study On Landscape Disign Of Zhang-Shi Hignway

As highway construction concept development, demonds highway are not restricted in safty, convenience and durability, and more and more attentions are paid on ecological-way and parkway. Consequently, deep and systematic research on highway landscape design is made in this paper, aming at making highway and landscape harmony and unification.In this paper, way of highway landscape characteristic sections division is studied, and the priciples for highway landscape characteristic sections division is proposed. On the basis of analyzing typical view deck in China, considering setting priciples as well as setting elements are got, and typical design scheme is put forward.By consider of there's no principle in slope landscape design, the concept of visuable slope is proposed, and correspongding landscape design method is discussed. In addition, because of poor landscape effect of traditional slope protection methods, the way of combing masonry and ecological slope protection is proposed.In this paper, first, study on conditions of typical emergency lanes in China is made. Then, considering pratical situation, the concept of over loading should be taken in consideration when designing emergency lanes is proposed. Consequently, theoraticla calculation of draw-in speed is made, which means the speed should be 130 or 145km / h. In addition, study on highway tunnel portal landscape design is also done, and correspongding design method and main points are proposed.At last, taking Zhang-Shi highway as practical construction, combing humane character, natural landscape and environmental character, schemes about highway landscape characteristic sections, view deck setting, typical slope landscape as well as protection, emergency lane and tunnal portal landscape on Zhang-Shi road is proposed, some of them have been successfully applied in this pratical construction.
