桥梁荷载试验
Bridge load test
在对桥梁进行了外观病害检查和结构材料检测之后,根据检测结果对破损严重、结构材料状况差的桥梁进行桥梁荷载试验。其目的是通过对桥梁按设计荷载直接加载,测试桥梁在不利荷载作用下的实际响应,以进一步分析和了解桥梁的工作状态,从而判断桥梁结构的实际承载能力。
After the inspection of the appearance of the bridge and the inspection of the structural material, the bridge load test is carried out on the bridge which is badly damaged and the structure material is poor according to the test results. The purpose is to test the actual response of bridge under the adverse load by loading the bridge directly under the design load, so as to further analyze and understand the working state of the bridge, so as to judge the actual bearing capacity of the bridge structure.
通过动载试验可测定桥梁结构动力特性参数和在动力荷载作用下的强迫振动响应,确定桥梁在车辆荷载作用下的动力效应及使用条件。
Dynamic load test can be used to determine the dynamic characteristic parameters of bridge structure and the forced vibration response under the action of dynamic load, and the dynamic effect and use condition of bridge under vehicle load are determined.
静载试验则根据不同桥型、不同设计荷载,按等效原则设计不同的加载工况,通过对桥梁实际加载,检测桥梁不利截面的变形和受力状态,从而推断桥梁结构在荷载作用下的实际工作状态和使用承载能力。
In the static load test, the different loading conditions are designed according to the equivalent principle according to the different bridge type and different design load. Through the actual loading of the bridge, the deformation and the stress state of the bridge are detected, thus the actual working state and the carrying capacity of the bridge structure under the load are inferred.
桥梁荷载试验的方法是在桥梁结构主要控制截面安装各种传感器,在规定荷载作用下,通过仪器记录桥梁受力和变形数据,并根据这些数据判断桥梁的承载能力状况,为维护桥梁的措施决策提供科学依据。
The bridge load test method is to install various sensors on the main control section of the bridge structure. Under the prescribed load, the load and deformation data of the bridge are recorded by the instrument, and the load bearing capacity of the bridge is judged according to these data, which provides scientific basis for the maintenance of bridge measures.
