通过对一座修建于20世纪70年代的8×30m圬工拱桥进行静动载试验,对比了原设计荷载汽车-15级、拖-60级与现有规范中公路-Ⅱ荷载下的桥梁静动载反应,分析判断了该拱桥的现有承载能力及使用性能。
Through the static and dynamic tests of an 8 × 30m arch bridge constructed in the 1970s, the static-dynamic tests of the original designed load vehicles -15 and -60 are compared with the existing ones Containing reaction, analysis to determine the existing carrying capacity of the arch bridge and performance.
