四川省某大桥静载试验分析

Analysis of static loading test of a bridge in Sichuan Province

为检验大桥的实际承载能力,对该桥进行静载试验。试验过程中,对各个加载工况所产生的挠度和应变进行测量,并将实测值与设计理论计算值进行对比,直接了解大桥在试验荷载作用下的实际工作状态和一些理论上难以计算部位的受力状态,以及一般性桥梁检查难以发现的隐蔽缺陷,判别桥梁结构的安全承载力和使用条件。

In order to evaluate the actual bearing capacity of a bridge, the static loading test is made. During the test, the deflection and strain are measured based on each loading condition. The measured value and the design theoretical calculation value are contrasted to assess the bridge＇s actual working status in the loading test and some parts which are theoretically difficult to calculate the stress. The hidden defects difficult to find under the general test conditions. The security bearing capacity and service conditions of the bridge structure are there for known for the design.
