摘要
由于设计考虑不足、施工质量较差等原因,梁板在运营阶段产生单板受力状态,致使铰缝破坏,从而影响结构安全及行车的舒适性。通过对设计理论、桥梁铰缝实际破坏的形态进行分析,提出防治措施。研究表明:采用深铰缝、加强桥面铺装、改进施工工序、板底横向粘贴钢板是防治桥梁铰缝破坏的有效途径。
Beam-slab systems are in veneer stress state during the operation stage because of poor design,poor construction quality and other reasons.These led to hinge joints damage.So the structure isn't safety and driving isn't comfortable.Some measures are put forward after the analysis of the design theory and the hinge joints' damage forms.In detail,the effective ways of preventing the hinge joints' damage are using deep-hinge joints,strengthening deck pavement,improving the construction procedure,the bottom horizontal reinforcement by pasting armor plate.
