三维曲面索塔自锚式悬索桥施工测量技术

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。

Survey to Construction for Self-anchored Suspension Bridge of 3D-Surface Tower

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 th...
