摘　　要：随着我国经济实力的增强和桥梁技术水平的提高,特大型桥梁日益增多,桥型也越加丰富,桥梁结构更加合理。文章以重庆朝天门长江大桥为例,就如何选址桥位、确定桥型及在确定的技术标准及荷载条件下如何开展结构设计、考虑施工因素提出设计思路。Accompanying the enhancement of China＇s economic strength and improvement of bridge construction technique, ultra-large bridges emerge increasingly, bridge types turn richer, and bridge structures become more rational. Taking Chongqing Chaotianmen Yantze River Bridge as an example, we put forward a train of thought for bridge design on choice of bridge site, determination of bridge type, and implementation of structural design and consideration of construction factors under definite technical standard and load condition.
