Abstract

Abstract: The cause that cracking procreate of PC continuous box girder bridges are many, In the final analysis,There are design?construction?manage and material. And that the design is mostly root, Therefore ameliorate the design thinking and Structure, so that reduce or control crack

Key words: PC continuous box girder bridges, design, structure, cracking

摘要： 预应力砼连续箱梁桥裂缝产生的原因是多种多样,但究其原因其根源无外乎来自设计、施工、管理养护和材料这4个层面。而设计是源头,把好设计关,即从设计思路、构造处理上加以注意和改进,从而使砼箱梁桥裂缝得到有效控制

关键词: 预应力砼连续箱桥梁, 设计, 构造, 裂缝
