| 以七里沟桥梁通行特载车辆的静、动载实时监测为例，介绍特载车辆通过桥梁时的监测方案制定及结构应变、挠度和沉降的监测方法。由实测数据分析可知，特载车辆通行时该桥的应变和挠度校验系数在同类桥校验系数的常值范围内，特载车辆通行后桥梁的动态参数基本不变，该桥承载力满足特载车辆通行的要求。 |

| Taking the real-time monitor of 569 t heavy trailer passing Qiligou bridge as an example, this paper introduces the monitor plan and method of monitor of structural strain, deflection and settlement.It is concluded that the check factors of the strain and defection for the bridge are in the normal range when heavy trailer passing it.It also finds that the dynamic parameters of the bridge are almost unchanged.The research results prove that load capacity of the bridge is satisfied for the heavy trailer passing. |
