深水钻孔灌注桩主墩施工平台设计研究

Design and Research of Construction Platform for Main Pier of Deep Water Bored Pile

以某长江主航道桥钻孔灌注桩主墩施工平台为工程背景,针对该平台设计难点,详细介绍了平台的结构布置、设计荷载、计算工况以及模型计算分析结果等,得出了深水钻孔灌注桩主墩平台设计的注意要点。文中可为后续深水钻孔灌注桩主墩施工平台设计提供技术参考。

Based on the construction platform for the main pier of a Yangtze River main channel bridge, and aiming at the design difficulties of the platform, the structure layout, design load, calculation conditions and model calculation analysis results of the platform are introduced in detail, and the key points for the design of the platform for the main pier of the deep-water bored pile are obtained. This paper can provide technical reference for the design of the construction platform of the main pier of deep-water bored pile in the future.
