Ⅱ型钢纤维混凝土轨枕的生产及室内静动载试验

介绍了 1998年在铁道部都匀桥梁工厂对六个钢纤维生产厂家的钢纤维砼轨枕进行了生产及试验对比 ,获得了各种不同钢纤维在混凝土中应用的抗压、抗折、劈裂及弹性模量等的试验结果。同时按照Ⅱ型轨枕的技术验收条件对各个厂家的钢纤维混凝土轨枕进行了静载及疲劳试验 ,取得了可贵的参考数据。由于当前推广钢纤维混凝土轨枕使用日益扩大 ,特在此篇论文中介绍有关资料以供参考

Producing and indoor experiments of Ⅱ type steel fiber concrete sleeper under dead and fatigue load

In this paper, based on the producing and indoor tests comparison of steel fiber reinforced concrete (SFRC) sleeper from six fiber manufacturer at the Duyun bridge factory of railway bureau in 1998, the test results of compressive strength, bending strength, split strength and elastic module of SFRC sleeper are introduced. Simultaneously, based on the tests of SFRC sleeper supplied by six fiber manufacturer subjected to dead load and fatigue load according to techno-acceptance standard about Ⅱtype steel fiber concrete sleeper, some valuable reference date is achieved. These relative test results and datum can be referred for engineer.
