主梁施工组织设计
1. 编制依据：
设计院提供的图纸资料；总监办下发的文件和要求， 《丽水XX大桥工程项目专用技术标准》ZCTC-02-368， 《公路工程质量评定标准》JTJ071-98， 《公路工程施工平安技术标准》JTJ076-95， 《公路工程桥涵施工技术标准》JTJ041-2000。 2. 概述：
工程概况
本工程主桥为160+160米单塔双索面预应力砼斜拉桥，主梁、塔墩固结体系。主梁为预应力砼肋板式梁，梁面顶宽，底部宽，梁高。每一施工梁段均有两道横隔板，其纵向间距一样为4m，厚度。主梁砼设计强度为C55，共6607M3砼。主梁纵向设有适量的预应力直线钢束，以提高主梁抗裂性和抗击施工中局部拉应力，该直线钢束拟采纳连接器接长。桥面板部份设置纵向?25精轧螺纹钢预应力，并采纳连接器接长。
斜拉索在塔上垂直索距～米，在梁上水平纵向索距为8米，塔端、梁端都为张拉端锚具，与梁段相对应，设17层索，共计68根。斜拉索长度为～，重量为～，单根索的张拉力为210T～410T。斜拉索为高强低松弛镀锌平行钢丝制成的热挤聚乙烯成品拉索, 镀锌钢丝直径为
7mm，标准强度品级为1670Mpa，钢丝性能符合GB5223-85《预应力混凝土用钢丝》的规定要求。拉索防护: 镀锌钢丝扭 -2-
