公路桥梁的伸缩缝已成为桥梁施工和维护的难题之一。研究、设计和制造使用更好的伸缩装置固然十分重要,但从另一方面讲,如能采用无伸缩装置的桥梁结构,则是从根本上解决桥梁由于伸缩装置遭受毁坏的现象。因此,世界各国的学者都在努力寻求最好的伸缩缝结构,得到的结论是“最好的伸缩缝是无伸缩缝”。因此,无伸缩缝桥梁应运而生。为此,结合实际工作经验对无伸缩缝桥梁的一些影响因素进行分析,并提出了具体的支持结论。
Highway bridge expansion joints have become one of the problems of bridge construction and maintenance. It is important to study, design and manufacture better telescopic units, but on the other hand, the use of bridge structures without telescoping means a fundamental solution to the bridge’s devastation caused by the telescopic units. Therefore, scholars all over the world are striving to find the best expansion joint structure, and the conclusion is that “the best expansion joint is a non-expansion joint.” Therefore, no expansion joints bridge came into being. For this reason, some influencing factors of bridge without expansion joints are analyzed according to actual working experiences, and concrete support conclusions are put forward.
