对1座索塔为贝壳状弧形壳体,主缆和吊索为空间线形,桥面为顶推工艺的钢箱梁不对称自锚式城市悬索桥来说,施工测量方法的选择及精度是保证大桥质量、安全和美观的关键因素之一。文章对实施某三维曲面索塔悬索桥的施工测量技术进行了介绍。最后的检测结果表明,各项测量验收指标均满足规范和设计要求,达到或优于预期目标。

The selection and precision of survey method is very important for assuring quality,safety and profile of a dissymmetrical self-anchored suspension bridge of which the tower in arc shape likes a conch,and cables distributes in space,and the steel box girder of deck is installed by top jacking measure.This paper introduces an application of this survey method in construction of a 3D surface tower of a suspension bridge.The survey results at last show that every measure and acceptance index is satisfy with the requirements of standard and design,which can achieve or be superior to its desired goal.
