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。
針對分彆採用JTG D62—2004《公路鋼觔混凝土及預應力混凝土橋涵設計規範》和JTJ 023—85《公路鋼觔混凝土及預應力混凝土橋涵設計規範》設計的滿堂支架現澆施工連續樑橋進行可靠度對比分析，結果錶明：對于靠近邊支座1／2跨徑範圍內截麵的可靠指標而言，按JTJ 023—85規範進行計算的結果略大于按JTG D62—2004規範進行計算的結果，其餘截麵則相反。該結果可為類似橋樑設計和舊橋加固改造提供藉鑒。

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.
