Research On Highway Landscape Design Of Cold Area

In recent years, highway landscape design in cold area has being developed rapidly, while the research and the practice of highroad sight is still in the lower level comparatively, which makes against the traffic development in our country, and it doesn't accord with the requirement of sustainable developing theory. The highroad circumstance in cold area is very complex because of the influence of the climate. According to the section feature in cold area, it is a very important question for discussion to discuss the principle and method of the sight design.There are different restricted conditions to the vehicle in the highroad with different grade, and the constitution of sight and designing method are different too. The aim of this thesis is to study the sight design on second-grade highway landscape and non-restricted highway landscape. The first part is the introduction about the extension of the highway landscape in cold area and the meaning of the highway sight, and to summarize the constitutes of highroad sight from several aspects such as the elements of principal part of the highroad,the elements of distant perspective and the background,the element of phonology and the dummy elements, and the author will bring forward that there is the feature of seasonal aspect, In the second part, the author of the thesis will bring forward the gist of the theory of sight designing, that is the principle of aesthetics,bioclimatology,sight bionomics, on the basis of that, The author of the thesis will bring forward that highway landscape design in cold area have to combine some principles. The third part is to expatiate the sight in main line including rode line,road surface,and sub-grade slope. and some spot scenes including the bridge,the exit and the entrance of the tunnel, marking board, perspective platform,separated scene, and the designing methods of planting scene on the central belt,the green belt of the both side of the road,and the green for preventing snow. The author of the thesis took part in the scientific item of "the typical engineering sight design of the highway from JiXi to Ne He". On the basis of it, the author made a lot of research to complete this paper, and the scientific item will be briefly introduced in the latter part of the paper.The author of the thesis is to discuss the principle and the method through the manner of combining the theory and the practice, the purpose is to improve the traffic security, and the circumstance of taking bus, to give prominence to the cultural characteristic, and to accelerate the harmonious development of human beings and nature.
