ABSTRACT
Based on Guizhou mountain area, the characteristic of Guizhou mountain area and the characteristic of continuous rigid frame bridge were thought. An analysis about the advantage of this bridge type and the reason why this bridge type had energetic development in Guizhou mountain area was made. According to the collected literature and design information, the development status, including construction features, building materials, design theory and method, the key technique of construction and development prospect were revealed. Firstly, a review about the achievement of this bridge type in Guizhou mountain area was made. Then an induction and conclusion were given. In construction features, the parameter of bridge span and section was mainly introduced and a conclusion for the choice of this parameter was given. In materials, the characteristic and problem of present materials were analyzed, and then an outlook and advice for new materials, including lightweight and ultra high strength concrete and fiber reinforced composites, were given. In design, the method and key point in continuous rigid frame bridge design were reviewed; then mainly focusing on the durableness design, the limitation of the old bridge design specifications was concluded, and some ideas and an outlook were put forward for the new bridge design specifications. In construction, the construction method, the key step in construction, the common problems and solution were focused on. And the method, the affect and value of construction control in continuous rigid frame bridge were then simply introduced. In the end, the development of continuous rigid frame bridge is looking forward the future. This paper is expecting making some contribution for bridge construction in Guizhou mountain area and offering some basic information for beginners in bridge engineering.
