The Research Of Investigation And Protection Of Wind-rain Bridges Architecture In Zi River Upstream Basin

Wind and rain bridge in hunan region as an important component of the wind and rain bridge in China, has kept China's wind and rain bridge in common, both in structure, material, space form, and decorative art shows considerable geographical uniqueness, stable and reasonable structure and durable material is the root of the wind and rain bridge has been standing, this is China's wind and rain bridge to have the quality, and on the structure form, architectural style and artistic roots and displayed a variety of styles and distinctive regional, fully embodies the ancient working people of hunan outstanding wisdom and craftsmanship, also demonstrated the historical connotation of hunan culture.In the modern society's way of life, values, and ideology, under the impact of wind and rain bridge situation is like their survival environment, on the protection and inheritance faces all sorts of problems: the private stacking wood, and in accordance with the wind and rain bridge and bridge bridge building toilet pigsty, natural factors and human factors on the bridge damage, up and down a lot of unreasonable repairing damage to the bridge structure and decoration art, modern transportation to bridge the huge pressure of the wind and rain bridge per face increasingly serious security hidden danger, such as bending, cracking of bridge pier beam body, the upper structure collapse, skew, etc. Of wind and rain bridge zi river upstream basin of hunan region investigation and surveying and mapping, through scientific research methods to explore the protective measures.The research methods of this article is divided into the following points:(1) the first qualitative and quantitative, preliminary build evaluation system based on the technology of modern architecture;(2) from general to specific, from specific to general, again through typical examples of research, exploring hunan region of wind and rain bridge protection way and technical support;(3) the traditional research method combined with modern computer methods,for each a bridge of research on GPS positioning, establishing database of wind andrain bridge in hunan province distribution;(4) the selection of typical examples to build 3 d model, using the method of virtual simulation compared the measured results and simulation analysis;The research content of this article mainly divides into the following points:First, general overview the research target, brief expounds research background,significance, research status and research methods at home and abroad;Second, a brief introduction to the evolution of wind and rain bridge, with a table in the form of zi river upstream basin of wind and rain bridge structure, style, function and space analysis and sums up the main characteristics of wind and rain bridge zi river upstream basin.Third, to the field survey of surveying and mapping data and photographs for the first-hand information, reference books and literature at the same time, complement each other. From the structure, form, style and wind and rain bridge history to in-depth, put all the surveying and mapping data in graphics and drawing and collates them into a system of the model. Through the local Chronicles and local human geography environment to understand the local characteristic of wind and rain bridge;Fourth, according to the current domestic selected representative about the present situation of the protection of the wind and rain bridge wind and rain bridge is analyzed and three-dimensional model is established to restore the original appearance. In all the research work on the basis of long-term protection measures are put forward;The protection of the wind and rain bridge has remarkable practical significance and research value, zi river upstream basin wind and rain bridge in the wind and rain bridge zi river basin research system plays a very important position, it is also an important part of hunan culture at the same time.
