I'm from the school and the new bridge of Tai Overview


Line deep and wide -, Il suspension bridge theory and practice of computing into the nineties, along with the rapid development of China's economic construction, China gradually built more than a dozen large span suspension bridge. The main span of 450 meters from the Shantou Bay Bridge began, have been built or is building a main span of 888 meters of the Humen Bridge, the main span of 900 meters of the Xiling Yangtze River Bridge, the main span of 1,385 meters of the Jiangyin Yangtze River Bridge, as well as ongoing design Lingdingyang Bridge (total length of 27 kilometers, the main bridge spans 1,400 meters and 900 meters). This indicates that China in the field of long-span bridges into the world advanced level. Our school is the first study of modern long span suspension bridge theory and methods of construction units. Before the construction of the bridge above, on the suspension bridge analysis, the main cable-based computing, stiffening girder and anchorage structure, seismic design method,[link widoczny dla zalogowanych], aerodynamic stability,[link widoczny dla zalogowanych], construction methods and construction phase calculation and analysis, and many other aspects of the research made a lot of work and lectures in each unit, for the construction of long span suspension bridge which laid the theoretical foundation, but also trained professionals. The construction of the bridge in the process, I have participated in its programs the school selection, design and construction methods, research of key technologies. Research has been used in these projects, and achieved good social and economic benefits. 2 bridges design theory and experimental study of wind resistance with long-span bridges in the country in recent years gradually increased, the bridge structure during construction and operation phases of the growing emphasis on wind stability theory and experiment with our school's advantage, compared system carried out early wind characteristics of the bridge structure, and has on two Shi Yuzuo span suspension bridges, cable-stayed and carried out continuous rigid frame bridge or full bridge section model wind tunnel experiments, theory and experiment structure in terms of the flutter, buffeting, vibration and other issues of rain, the results praised by domestic and foreign counterparts, but also for the construction and operation of these bridges security and usability to provide a guarantee, for example, of a suspension bridge stiffening test beam cross-section of the original design study, found that wind can not meet the requirements of the construction unit in the study looked at my school, the use of cross-section of our form of the proposed changes. Span 263, a new prestressed concrete bridge and arch bridge reinforced with computing theory and method of construction of railway bridges in recent years toward the pier, a large cross, new direction, which river water to Southern Railway Bridge (main span 128 m prestressed concrete continuous rigid frame bridge, pier high lOO m), hi the old river bridge (88 meters span prestressed concrete continuous rigid frame bridge, pier 6O meters high), Nanpanjiang Badu Bridge (main span 9O m V type support prestressed concrete continuous beam bridge pier 70 meters high), and the board of its II Bridge (China's first railway prestressed concrete curved bridge, main span of 72 meters, 50 meters high pier) as the main representative. I attended one of three bridges school's scientific research work. Through theoretical and experimental research, high-pier shear properties in meters, v-type bridge supports overall force characteristics and V support the local stress analysis of curved bridges torsion,[link widoczny dla zalogowanych], distortion theory, curved bridges and construction of prestressed effect of phase calculation force analysis method, curve of friction loss prestressed beams, rigid frame nodes obtained in both the stress distribution of research results, and was applied in the design and construction. Reinforced with long span arch bridge in China developed rapidly in recent years as a bridge. Wanxian Yangtze River Bridge is the world's largest in the span of those kinds of structure (main span of 420 meters, crossed the river.) In addition to our school structure calculation of this theory, construction control calculation methods were in-depth study, but also made one-tenth scale model test (model span of 42 meters). Trial of this magnitude are rare even in foreign countries. Research in the design and construction of the bridge played an important role. The bridge is now open to traffic. t4 large span steel bridge static and dynamic characteristics of large span steel bridge in the static and dynamic characteristics of the bridge has been my school one of the important research subjects. Analysis of stress in the steel bridge in recent years the theory of coupled dynamic characteristics of bridge, the longitudinal force transmission mechanism, steel truss composite structure with characteristic analysis, steel pre-stressing technique, stability theory steel, steel bridge design and manufacturing,[link widoczny dla zalogowanych], and many other research,[link widoczny dla zalogowanych], the results are research, design, construction, manufacturing and other departments are used. For example, a suspension bridge above the steel stiffening beams in the design process, due to the recommendations of scholars, I was adopted, the structural characteristics of the bridge improvement and cost saving nearly a million. 27
