| 中文摘要:深水桩基础施工是桥梁建造的重要环节,而进行深水桩基础施工则必须先行搭建水上施工平台。因此进行科学合理的设计、采取正确可靠的施工工艺方法,对保证水上施工平台在建造过程中以及建成后的营运安全非常重要。以南阳市宛坪高速公路重阳水库大桥钻孔灌注桩水上施工平台为研究背景,运用ANSYS软件进行钢管桩支撑固定式水上施工平台力学行为分析,研究水上桩基施工平台结构设计的合理性,并且探讨平台结构的关键施工技术,为类似工程提供有益参考。 |

| Abstract:The construction of deepwater pile foundation is one of the important working procedures of bridge construction.It is necessary to build the fixed aquatic construction platform in order to construct the bored pile.So the construction platform must be scientifically designed and reasonably built,and it is very important to ensure the safety and stability of the platform in the whole course of building and working.Take the example of cast-in-place bored pile engineering for a large reservoir bridge,the mechanical behavior of the fixed aquatic construction platform braced by steel tube pile is analyzed with ANSYS software,the key technique is studied,and some conclusions are obtained that will be helpful to the similar engineering works. |
