| 摘 要： | 大跨度上承式拱桥的结构复杂,施工难度大,为保证桥梁施工安全,必须制定合理的施工监控方案.以大同市御河桥为研究对象,选择了7个应力监测断面和56个应变监测点模拟进行桥梁应力及应变的监测,并用有限元理论,模拟了该桥在10个特定工况条件下的受力及变形,分析显示模拟结果与实际情况较为接近.结果表明,御河大桥的监测断面及监测点选择合理,模拟方法合适,御河大桥的监测方案可为其他相似形式桥梁的施工监测提供借鉴.

| Abstract: | It is hard to construct a long-span deck-type arch bridge for its complex structure.In order to ensure the construction safety,the construction monitoring of a long-span deck-type arch bridge is more important than that of other type.The Yu River bridge in Datong city was chosen as the subject investigated.Stress monitoring and position monitoring were performed in 7 monitoring sections and 56 measuring points,and finite element analysis was used to simulate the stress and deformation of the bridge in 10 work conditions.The result of simulation agreed with the true condition.The choice of monitoring sections and measuring points was reasonable for Yu River bridge,and the way of simulation was appropriate.Thusly,it can provide a reference for the construction monitoring of other similar bridges. |
