JTG-TD65-01-2007公路斜拉桥实施细则.pdf

发表于 2010-1-30 17:16:28

本书为交通部发布的规范——公路斜拉桥设计细则（JTG/TD65-1—2007）本细则根据交通部“关于下达2001年度公路工程标准制修订工作计划的通知”（厅公路字［２００２］３６号）的要求，对《公路斜拉桥设计规范》（试行）（JTJ 027—96）进行修订而成。?
在修订过程中，编写组吸取了国内有关单位的研究成果和实际工程经验，借鉴了国外先进的规范、标准、设计方法，总结了施工经验，同时开展了有关设计参数的统计与研究。采取多种方式，广泛征求有关单位和个人的意见，反复讨论、修改后，由交通部审查定稿。?
本细则共分9章，与老规范相比有如下重大改进：在相关基础规范的基础上突出了斜拉桥的特点，编制对象以独塔斜拉桥和双塔斜拉桥为主，同时明确了本细则的适用范围；根据斜拉桥的设计实践经验，补充了斜拉桥总体设计有关要求，引入了合理成桥状态和合理施工状态的设计理念；进一步明确整体结构和局部结构的分析，同时补充细化了斜拉桥的设计计算内容及规定；通过对国内外已建成斜拉桥的工程实例有关参数的统计分析，提出了各类材料斜拉桥的适用跨径范围，充实了斜拉桥各组成部分的构造要求和钢绞线斜拉索的有关规定；结合当前斜拉桥建设与发展趋势，及时收入了有关梁、塔上钢锚箱锚固的构造要求，特别补充了钢锚箱和钢索塔的内容。此外，本细则还增加了斜拉桥施工控制与可养护检修设计的规定，提出了相关的基本要求、计算分析内容和工作流程。?
请有关单位在使用过程中，随时将问题和建议函告重庆交通科研设计院（重庆市南岸区学府大道33号，邮编：400067），以便再次修订时研用。??
