2、方向设置支架等预制部件。在待转桥体的岸端设铰，并将提升系统临时架设于桥台或台后，利用卷扬机来进行索引提升，使桥体能够竖向转体到合拢位置，然后在合拢处封固混凝土，完成竖转体施工竖转法竖转法适用范围适用范围竖转法在对于季节性河流或河流水深较浅搭设支架不困难的河流，常采用搭设简单支架组拼和现浇拱肋; 对于通航河流，也可采用工厂制造，浮船浮运至桥位，拱肋由下向上竖转至设计高程。也可采用桥台结构竖向搭设组拼或现浇拱肋的脚手架，拱肋由上向下竖转至设计高程。转体施工转体施工竖转法竖转法竖转体系一般由牵引系统、索塔、拉索组成。竖转的拉索索力在脱架时最大，因为此时拉索的水平角最小，产生的竖向分力也最小，而且拱肋

3、要实现从多跨支承到铰支承和扣点处索支承的过渡，脱架时要完成结构自身的变形与受力的转化。为使竖转脱架顺利，有时需在提升索点安置助升千斤顶。竖转体系竖转体系施工工艺施工工艺在施工工艺上,竖转铰的构造与安装精度,索鞍与牵转动力装置,索塔和锚固系统是保证竖转质量、转动顺利和安全的关键所在。国内的拱桥基本上为无铰拱,竖转铰是施工临时构造,所以,竖转铰的结构与精度应综合考虑满足施工要求和降低造价。跨径较小时,可采用插销式,跨径较大时可采用滚轴。拉索的牵引系统当跨径较小时,可采用卷扬机牵引;跨径较大,要求牵引力较大,牵引索也较多时,则应采用千斤顶液压同步系统。转体施工转体施工平转法平转法平转体系平转体系适用

4、范围适用范围平转施工法适合在山区深谷或平原跨线、跨河的桥梁施工。平转施工法是指在桥位外，横向利用两侧地形搭设支架。并在桥墩底部设置转动体系，利用张拉锚扣体系实现重力平衡，采用适当的索引设备将桥体平转到合龙位置。然后浇筑合龙段混凝土，封固转盘。转体施工转体施工平转法平转法平转体系平转体系平转体系转动平衡体系平衡转动体转体施工无平衡重转体施工转动牵引体系上转盘下转盘转动牵引体系转动施工转动施工平竖转结合法平竖转结合法平竖转结合法: 要兼具以上两种施工条件，比如在平原区，当跨越宽阔河流及桥位地形较平坦时，采用平转法施工难以有效利用地形，宜采用竖转与平转相结合的方法。Testing Methodolo
