摘要
连续刚构梁多用于大跨径高墩结构桥,具有结构刚度好、行车平顺性好、养护简易、抗震性能好、易于悬臂施工等优点。以广东省中山市三角镇福源路至阜港公路鸡鸦水道特大桥为例,介绍(50+75+135+75+50)m五跨预应力混凝土连续刚构组合梁桥的设计特点,并简要介绍其施工方法,以期为同类型桥梁设计提供借鉴。
The artical introduces JiYa watercourse extra - long bridge on the road from the town of Sanjiao in ZhongSban city to the town of Fugang. It discusses the design features of （50 ＋75 ＋ 135 ＋75 ＋50）m prestressed concrete continuous-rigidity structure beam bridges and briefly introduces its construction methods.
