越南白城大桥与中国崖门大桥的设计和施工

Designs and Constructions of Vietnamess Baicheng Bridge and Chinese Yamen Bridge

研究目的:对比介绍国内外在台风地区、风景名胜景点桥梁的造型、桥梁结构及施工方法。研究结论:单索面斜拉桥以其轻柔的造型易融合于周围的景观,在减震器的作用下,桥梁横向抗风可以满足设计和施工要求。本文从景观设计、下部基础和上部结构、抗风和斜拉索设计以及桥梁监控系统等方面介绍了越南白城大桥和中国广东崖门大桥,两桥在设计和施工中都运用了各国先进的科学技术。其中越南采用钢三角斜撑加预应力创新技术及在现代科技条件下采用传统的气压沉箱法施工值得我们研究学习。

Research purposes： The introductions are given to the moldings, structures and construction methods of the bridges in typhoon zones and scenery zones at home and abroad. Research conclusions： The single cable face cable- stayed bridge can easily integrated into the surrounding scenes because of its light molding and it can meet the requirement of wind resistance in lateral direction with help of buffer. The introductions are given in this paper to the advanced technologies applied in design and construction of scenes, upper and bottom structures, wind resistance and cable staying for Vienames Baicheng Bridge and Chinese Yamen Bridge. In which the innovative technology of steel delta support with prestress and pneumatic caisson method applied in construction of Vienames Baicheng Bridge are worth studying.
