摘　　要：连续刚构跨越能力强,稳定性好,在山区高墩桥梁中得到广泛应用。由于大角度斜交桥梁存在梁体爬移的隐患,其多采用墩梁固结。某桥梁位于孝感市,跨老澴河,采用斜交矮墩连续刚构体系实现“莲绽澴水”的景观效果。文章介绍该桥总体方案、结构体系以及主梁与桥墩的构造和线形,并对主梁进行梁格法分析,采用分离式桥墩墩顶扩头、墩梁固结方法,解决了墩顶弯矩大和斜桥爬移的问题。该桥建成后,线形流畅、形态优美,为斜交滨水桥梁景观设计开辟了新思路。The continuous rigid frame has strong crossing ability and good stability,and it is widely used in the bridge with high piers in mountainous area.Due to the hidden danger of beam creep in the large angle skewed bridge,the pier beam consolidation is often used.A bridge is located in Xiaogan city,crossing the Laohe river.It adopts the continuous rigid frame system with skewed low piers to achieve the landscape effect of"Lotus blossom in water".The overall scheme,structural system,and the construction and linearity of the main beam and piers of the bridge are introduced,and the main beam is analyzed by using the beam grid method.The consolidation method of pier top expansion and pier beam for the separated bridge pier is adopted,so as to solve the problems of large bending moment at the pier top and creep of skewed bridge.After the completion,the bridge has a smooth linearity and beautiful shape,opening up new ideas for the landscape design of the skewed waterfront bridge.
