关于无伸缩缝公路桥梁及设计的分析

Analysis of Jointless Highway Bridge and Its Design

公路桥梁的伸缩缝历来是桥梁施工、维护中的难题,公路桥梁的伸缩装置属于高损耗性设备,损害情况严重。无伸缩装置的桥梁便应运而生,取消伸缩装置的无伸缩缝桥梁有效避免了伸缩装置安装不当引起的各种问题,从而缩减了工程造价,降低了维修成本,就无伸缩缝公路桥梁及其设计展开探讨、分析,有关经验可供相关专业人员参考。

The expansion joint of highway bridge is always the difficulty in the bridge construction and maintenance.The expansion device of highway bridge belongs to the high-loss equipment, and is seriously damaged.Therefore, the jointless bridge is proposed. The jointless bridge without the expansion device can efficiently avoid various problems caused by the improper installation of expansion device so as to decrease the engineering construction cost and reduce the maintenance cost. The article discusses and analyzes the jointless highway bridge and its design. The relative experience can be referred for the similar projects.
