连续刚构桥的主要病害及其成因机理分析
|
摘要
连续刚构桥是预应力混凝土梁式桥的一种较为新颖的桥梁体系,有其独特的结构特征和受力体系,受力合理,应用广泛,但在使用过程中也发现了跨中下挠和梁体裂缝等缺陷,文章对连续刚构桥的主要病害特征和产生病害的原因作了相应的分析,并提出相应的对策来减小桥梁的病害,旨在为工程技术人员在连续刚构桥的设计和施工上提供参考。
The continuous rigid-frame bridge,a kind of fresh seytems of prestress concrete-beam bridge,has special structural character and forced system.This kind of bridge is forced reasonably and used widely,but has some disadvantages such as middle deflection and bodily cracks.The primary character and the reason of these diseases that spring up in the bridge are discussed in this paper where the corresponding resolvents are given to reduce the diseases,that is in order to provide a reference for engineering technicians on the design and the construction.
