桥梁的静载试验是将静止的荷载作用在桥梁上的指定位置,然后对桥梁结构的静力挠度、应力应变、裂缝等参量进行测试,从而对桥梁结构在荷载作用下的工作性能及使用能力作出评价,静载试验作为桥梁结构试验中最常用的基本试验,成为了解结构性能的重要手段,在评价桥梁承载能力方面有非常重要的作用。下文通过对阿尔及利亚东西高速公路中RN13互通内跨越高速公路的桥梁静载试验,介绍静载试验方案、试验荷载计算、测点的布置情况以及在静载试验中应注意的事项。
The static load test of the bridge is to apply the static load to the designated position on the bridge, and then to test the parameters such as the static deflection, the stress, the strain and the crack of the bridge structure, so as to test the working performance and the capability of the bridge structure under the load As an evaluation, static load test, as the most commonly used basic test in bridge structure test, becomes an important means to understand the structural performance and plays a very important role in evaluating the bearing capacity of bridge. The static load test scheme, the test load calculation, the arrangement of measuring points and the items to be noticed in the static load test are introduced in the following through the static load test of the bridge across the freeway in the RN13 intercommunication in Algerian East-West Expressway.
