23、长1930.6m，其中主桥580m，两岸引桥长1350.6m。道路等级为城市主干道，双向六车道，河道内引桥桥宽28m，河道外引桥宽25m，主桥桥宽30m。主桥施工场地均位于韩江大堤内，其中Z1、Z4、Z5、Z6墩位于沙滩上，Z2墩位于航道浅水边，这五个桥墩采用填砂石形成施工作业平台(韩基标高9.5m),Z3墩位于韩江航道中。韩江枯水期水位在7.5m左右，雨季期间水位上涨到14m左右，而且水流冲刷破坏严重。1.2结构形式主桥上部为五跨连续无风撑钢管混凝土系杆拱桥(C跨+B跨+A跨+B跨+C跨)，其跨径组合为（85m+114m+160m+114m+85m）；下部为钻孔桩基础、矩形承台、双薄壁矩形空

V型结构总体施工方案概述2.1施工特点平衡塔斜拉施工方法是利用拉杆向上斜拉，通过中间塔平衡水平分力及抵消部分力矩，结构受力分析比较明确，充分利用型钢的轴向抗拉及抗压性能，这种方法不受桥墩高度限制，支架体系也不受桥下洪水的影响；此外，因施工支架不落地，在进行V型结构施工期间，还可以同时进行上部箱梁的基础处理及搭设部分支架，有利于加快进度。2.2施工方法采用型钢在空心墩顶上组拼为平衡塔，通过中间塔平衡水平分力及抵消部分力矩。V腿外侧利用贝雷梁组拼为斜托梁，斜托梁底部与墩顶预埋件销接，中部及顶部通过型钢斜向拉在平衡塔上。V
28、腿砼浇筑后利用水平刚性拉杆临时固定，水平拉杆与V腿形成临时倒三角稳定结构，直至顶部箱梁施工后形成永久三角形结构。V腿为空心薄壁变截面状，结构复杂，操作空间狭小，而且混凝土方量大，为了降低施工荷载，并减少混凝土的收缩及徐变应力，将Z3(Z4)墩V腿结构分三次先后浇筑砼，第一次浇筑根部，第二次浇筑空心段，第三次浇筑顶部实心段；Z1(Z6)、 Z2(Z5)墩V腿分两次浇筑砼，第一次浇筑根部及空心段，第二次浇筑顶部实心段。2.3 主要施工步骤(以Z3为例)第一步：空心墩顶部实心段施工后，利用汽车吊或塔吊安装平衡塔、斜托梁、斜向拉杆，人工安装第一节模板，绑扎钢筋，浇筑根部砼。第二步：安装第二节模板，绑扎
29、钢筋，调整模板至斜腿位置，凿毛砼接头并清理干净，两侧对称浇筑空心段砼。第三步：安装第三节模板，绑扎钢筋，预埋型钢水平拉杆，调整模板至斜腿位置，凿毛砼接头并清理干净，两则对称浇筑顶部砼。第四步：砼达到90%设计强度后，利用预埋的型钢水平拉杆与V腿形成临时稳定三角结构，割除斜托梁及斜向拉杆，施工上部现浇箱梁。主要施工步骤如图3所示。ampliaci, introducci i projectes de transformaci tcnica daconseguir tres simultnies. 5, reforar leducaci viria pensaments en tots els q
