金马大桥设计实践与理论探索

Design practice and theoretical exploration of Jinma Bridge

金马大桥全长1912．6m．主桥是60m＋283m＋283m＋60m的独塔混凝土斜拉桥与T型刚构协作体系，为同类型之世界级大桥．引桥全长1226．6m．是先简文后连续预应力混凝土T梁桥．作者在设计时采用了一些新的设计思想，并对设计理论作了有益的探索．

The total length of Jinma Bridge is 1912. 6m,the main spans of Jinma Bridge arecooperative system constituted of a single tower concrete cable-stayed bridge and a T-rigid framebridge. The length of the main spans of Jinma Bridge is (60 + 283 + 283 + 60)m, which is theworld-class among the same style bridges. The total length of bridge approach is 1226. 6m. Thestyle of the bridge approach is simple and continuous support PC T-beam structure. New designtheory, which is beneficial to extend the design theory of bridge, is adopted by the designer.
