前言根据铁道部基建局的可靠度科研任务,1986年5月,由上海铁道学院土木系组成现场测试小组,在蚌埠分局宿县工务段协助下,对津浦线浍河大桥(跨度为64米栓焊桁梁)的构件动应力进行现场实测,主要是用以检验桁梁各种构件的疲劳承载能力及估算可靠度指标β值。
Preface According to the reliability research mission of the Ministry of Railways Infrastructure Bureau, in May 1986, a field test team was formed by the Department of Civil Engineering of Shanghai Railway Institute. With the assistance of Suxian County Public Security Bureau of Bengbu Branch, Welded truss girder) component of the dynamic stress field measurements, mainly to test the fatigue load carrying capacity of various components of truss girders and estimate the reliability index β value.
