摘要
通过对比分析组拼式和整体桁架式两种围囹钢板桩围堰施工方案的优缺点,结合穗莞深城际铁路东宝河特大桥承台工程,介绍了整体桁架式围囹钢板桩围堰应用情况,并阐述了该围堰的设计计算方法及施工工艺要点,指出该钢板桩围堰结构简单、受力明确、稳定可靠,保证了承台和墩柱的施工质量。
Through comparatively analyzing construction scheme merits and defects of two kinds of spelling-style wailing steel sheet pile cofferdam and truss-style wailing steel sheet pile cofferdam,combining with Dongbao river bridge cap engineering of Suiguanshen intercity railway,the thesis introduces the application conditions of integral truss-style wailing steel sheet pile cofferdam,describes its design methods and construction points,and points outs its advantages,such as simple structure,clear stress and stable reliability. As a result,it guarantees the construction quality of the cap and pier column.
