跨铁路步履式多点顶推钢箱梁施工技术

结合宁波市福明路半漂浮体系的双塔双索面斜拉桥钢箱梁的施工项目，对步履式多点顶推法施工中的临时墩设置、导梁设计、顶推设备作简单叙述，对顶推施工中的同步顶推、纠偏、控制力和位移控制措施及注意事项等进行了详细介绍。可为今后同类型桥梁的施工提供参考。

ydraulic Walking, Multi-Point Launching Construction Techniques for Steel Box Girders Across an Existing Railway

With the construction of the steel box girders of the cable-stayed bridge of the semi-floating system with double py- lons and double cable planes at the Fuming Road of Ningbo City as a practical example, the hydraulic walking, multi-point launching construction techniques are dealt with in the paper, with the provision of temporary piles, the design of the guide beams, and launching equipment briefly introduced. The construction of the project may serve as a useful reference for bridges of the same type in the future.
