摘要
单索面斜拉桥受力较双索面斜拉桥更为复杂,主要表现在面外稳定性以及结构振动特性的变化[1]。其次由于各斜拉索强度不能做到完全相同,钢索索力也难均匀分配给各个单丝,因此斜拉索索力是影响桥梁安全运营的关键因素。以某座单索面斜拉桥为对象对该桥动、静载试验加载方案进行了设计,然后进行现场试验,得到了此次静载试验的校验系数及桥梁振动数据,在此基础上对测试结果进行了理论分析。
For a single cable plane cable-stayed bridge as the object, this paper designed the loading scheme for the bridge dynamic and static load test. Then it had the field test and obtained the calibration coefficient and bridge vibration data of the static＇, load test. On the basis of this, it analyzed the test results in tileory.
