摘要
以山西某大桥静载试验为例,桥梁受荷过程中的最不利位置为边跨和中跨正弯矩部位和墩顶最大负弯矩部位。根据工程实际情况,设计出6种不同的荷载工况以及8种荷载布置方式进行加载观测,通过对受荷桥梁的挠度、应力观测结果分析得出十里河大桥满足承载性能要求,试验工况及测点布置方案在类似工程中具有借鉴参考意义。
Static loading test has been done here to a certain bridge in Shanxi Province. As we all know, the most disadvantageous positions in the loading process are the positive bending parts of sidespan and midspan as well as the maximum negative bending part of the pier top. According to the actuarial situation of the project, 6 different types of load cases have been designed and 8 types of load arrangements have been carried out to observe the loading. Through the analysis of deflection and stress of the bridge, it is concluded that Shi Lihe Bridge can satisfy the requirements of load - carrying properties. The case of the test and lying out of measure points can be taken as reference in the following similar projects.
