桥梁转体施工是一种新的施工工艺。自1977年四川省遂宁县建设桥(我国第一座转体施工的桥梁)转体施工成功以来,先后在许多省份得到推广。特别是四川省主跨122米巫山龙门大桥及主跨200米涪陵大桥无平衡重转体成功,更展示了转体施工的生命力,将该施工工艺推向了一个新的阶段。平衡重转体施工由于需要相当重量的平衡重维持转动体系的稳定,因而增大跨径要受到一定的影响;无平衡重转体施工由于减少平衡的圬工数量,其转体重量轻,能增大跨径,具有一定的经济性等优点,确实是一种很好的转
Bridge construction is a new type of construction technology. Since the success of the swivel construction of Suining County Bridge (the first bridge of China’s swivel construction) in 1977, it has been promoted in many provinces successively. In particular, the main span of 122 meters Wushan Longmen Bridge in Sichuan Province and the main span of 200 meters Fuling Bridge unbalanced heavy body success, but also demonstrated the vitality of swivel construction, the construction technology to a new stage. Balance weight heavy body construction due to the need for a considerable weight of the balance weight to maintain the stability of the rotating system, thus increasing the span to be affected to some extent; no balance heavy body construction due to reduce the balance of the number of workers, the swivel light weight, can Increase span, with a certain economy, etc., is indeed a good turn
