摘要
鉴于国内较多空腹式圬工拱桥存在较为严重的病害,其受力性能不确定且结构存在一定的安全隐患,针对某空腹式圬工拱桥开展了静载试验,通过计算分析及现场试验,得出了桥梁的应变、变形、校验系数等技术指标,对桥梁的整体受力状况进行了综合评定,为桥梁后续的管养提供依据。
In view of the serious existing damage of domestic leaning-type masonry arch bridges,the mechanical properties are uncertain and there are some safety hidden troubles in the structure. A static load test of a certain leaning-type masonry arch bridge was carried out. The technical indexes such as strain,deformation and calibration coefficient,and comprehensive assessment of the overall stress status of the bridge are obtained,by means of calculation analysis and field tests,which provide the basis for the follow-up management of the bridge.
