摘要
交通部新修订的行业标准《公路桥梁板式橡胶支座》JT/T 4-2004代替JT/T 4-1993和JT 3132.3-90,已于2004年6月1日正式实施。新标准对比原标准有较大变化,在内容上做了重大修改调整和补充,使现行标准条文内容更趋于完善。其中对部分力学性能项目的计算和检测方法及对测试结果的评价做出了规定。本文根据JJF 1059-1999《测量不确定度评定与表示》的要求,系统地对公路桥梁板式橡胶支座的抗压弹性模量检测结果的不确定度进行了研究。针对橡胶支座性能检测结果的不确定度特点,分析了测试过程中的方法、设备、量具和检测环境等因素对测试结果的影响程度。
The new professional standard ＂Plate Type Elastomeric Pad Bearings for Highway Bridges＂ 《JT/T4-2004》 replaces the JT/04-1993 and JT3132.3-90. The standard has been already released on June 1 in 2004 formally. The content of the new standard is significantly revised and added in comparvison tO the old standard . The test methods of mechanic properties and the evaluation of test results of elastomeric pad bearings have been stipulated particularly. The uncertainty of compression modulus of elastomeric pad bearings is evaluated and researched. To aim at the uncertainty characteristics of the detecting results of elastomeric pad bearings, the influence degree of factors of test mathods, equipments, mesuring device, measuring environment etc. are analyzed.
