The Qin Dynasty To Qing Dynasty Guanzhong Region Bridge Technology Research

The bridge is a common and very special building. That it is ordinary, because crossing the river valleys necessary, coupled with the rapid urban development, overpass, the overpass has also become important to ensure that our smooth passage facilities. Say it is special, because the bridge is built on the ground, building line in the air. Due to its specificity, it determines it has its own unique structural design and special material selection requirements. Bridge to meet the basic access requirements, and its artistic With improvement in technology constantly high. Reasonable structure coupled with its unique design, architectural history one after another classic. Xi’an, the ancient capital of thirteen, who is the core of China’s political, economic and cultural region, so the more rapid the development of road traffic in the Guanzhong area. Since the Qin to the Tang Dynasty construction techniques of bridge can be called the highest in the country. After since the Tang Dynasty, Xi’an enter the capital of the times, although the center of the political, economic, transfer and exchange of Guanzhong Plain in the east and west must pass through successive dynasties in Guanzhong area bridge construction has been quite seriously. This paper will be divided into age, selected sample of bridges, Guanzhong region bridge construction techniques from different periods of Qin and Han to the Ming and Qing trial. The text is divided into five chapters.An ancient bridge in China. This section is from the ancient bridge type, the difference between a variety of bridges, as well as the technology used, an overview of the development of the bridge. From the national bridge technical characteristics point of view, the development and change of the bridge is accompanied by economic development and the advancement of technology. Of course, the regional developments also very obvious.Qin and Han Dynasty in Guanzhong area bridge technology research. This chapter from the Qin and Han Dynasty in Guanzhong area, select a representative bridge research,Wei he Bridge, Baqiao, Shahe Old Bridge, Pu Jindu as the object of study, the material of this period in Guanzhong area bridges, irrigation purposes, the construction of The scale of research and analysis.Third, during the Sui, Tang and Song Dynasty in Guanzhong area bridge technology. This chapter mainly selected Tang Wei River Third Bridge study found Tang Tung Wei River Bridge archaeological relics unearthed study. West Wei River Bridge and the Wei River bridge literature. Elaborate on the bridge of the Tang Dynasty in Guanzhong region size, shape, etc., in order to reflect the characteristics of the Guanzhong area bridges.Fourth, the Yuan, Ming and Qing Dynasty in Guanzhong area bridge technology research. This chapter selects Baqiao, Longqiao as thisA period off the bridge of the most representative study. Study found that the material of the region in this period off the main bridge has been changed from wood to more durable stone. Bridge construction technology is also undergoing change, combined with their own needs and the specific environmental constraints on the basis of integration around the bridge characteristics to be improved in order to extend the life ofthe bridge.Five, summary. From the Qin to clear this two thousand years in, whether it is thecapital of the era after the capital of the times, the Guanzhong region have animportant traffic position. Built the bridge regardless of material or construction technology with the development of science and technology taking place to change. In terms of material, with improved stone mining capacity and processing capacity, durable bridge stone bridge has become the first choice. Construction Improvement also makes people better able to control the quality and construction progress of the bridge. But in any case change in the Guanzhong area bridges has its own characteristics, from the construction technically speaking; the dry construction has been in use the Millennium and has not changed. Bridge shapes for the beam bridge this the most common type of bridge still in use. It can be said that the development of the bridge in the Guanzhong region is advancing with the times, continuing to build, innovative, take the other bridge director, local conditions, construction spread BES, a bridge with the Guanzhong characteristics.
