摘要
针对分别采用JTG D62—2004《公路钢筋混凝土及预应力混凝土桥涵设计规范》和JTJ 023—85《公路钢筋混凝土及预应力混凝土桥涵设计规范》设计的满堂支架现浇施工连续梁桥进行可靠度对比分析,结果表明:对于靠近边支座1/2跨径范围内截面的可靠指标而言,按JTJ 023—85规范进行计算的结果略大于按JTG D62—2004规范进行计算的结果,其余截面则相反。该结果可为类似桥梁设计和旧桥加固改造提供借鉴。
This paper performs comparative analysis for reliability of full - support continuous beam bridges in cast - in - situ construction designed as per JTG D62 - 2004 ＂Design Code for Highway Reinforced Concrete and Prestressed Concrete Bridges and Culverts＂ and JTJ 023 -85 Design Code for Highway Reinforced Concrete and Prestressed Concrete Bridges and Culverts＂, the result shows that for reliability index of cross section close to 1/2 span of side supports the result calculated as per the JTJ 023 - 85 specification is slightly larger than the result calculated as per the JTG D62 -2004 specification, the other cross sections are opposite. The result can provide a reference for design of similar bridges and reinforced reconstruction of old bridges.
