连续钢构桥成桥荷载试验实施方案研究

新建连续钢构桥的质量是保证桥梁安全运营的关键,因此,成桥后通过荷载试验对桥梁质量进行评定以评判桥梁的质量,确保桥梁安全运营,防止安全事故发生就显得至关重要。本文对连续钢构桥成桥荷载试验实施方案进行研究,确定了此类桥梁的试验内容、提出了静载试验方案的加荷原则、控制截面、试验工况和测点布置原则以及动载试验方案的测试内容和脉冲试验、跑车试验、跳车试验、刹车试验的试验方法。运用这些原则和方法能够对新建桥梁的质量进行详细鉴定,以检验设计理论以及施工质量,为即将投入使用的桥梁的运营、养护提供依据。

Continuous rigid frame bridge load test of the implementation of the program

Continuous rigid frame bridge built quality is the key to ensure the safe operation of the bridge,so the bridge into the bridge by load tests in order to judge the quality assessment of the quality of the bridge is very important,to ensure the safe operation of the bridge and to prevent security incidents.In this paper,continuous rigid frame bridge into the bridge program was studied,the implementation of load test to determine the content of this type of bridge test was given,static load test is proposed based on the principle of loading the program,the control section,test conditions and the principle of measuring points and the dynamic test program test content and pulse testing,car testing,Bump tests,test methods for brake testing.These principles and methods used on the new bridge can conduct a detailed appraisal of quality to test the quality of design theory and construction for the bridge,which can provide the basis for operation and conservation.
