摘要
针对深水浅覆盖层水域桥梁承台及墩柱施工中所面临的一系列问题,提出了一种“既有钢护筒+钢板桩围堰”的组合式围堰结构,基于理论计算、数值模拟、现场检验等手段,对此组合围堰结构进行了分析。结果表明该组合式围堰结构弥补了钢围堰本身入土浅所造成的抗滑移、抗倾覆、整体稳定性不足等问题,对今后类似深水、浅覆盖层水中墩台围堰施工,具有很高的参考和推广价值。
Aiming at a series of problems faced in the construction of bridge cushion caps and pier columns in deep water and shallow overburden water,a combined cofferdam structure of“existing steel casing+steel sheet pile cofferdam”is proposed.And based on theoretical calculations,numerical simulations,field inspection and other method,the combined cofferdam structure is analyzed.The research results show that the combined cofferdam structure compensates for the problems of anti-sliding,anti-overturning,and overall stability caused by the shallow penetration of the steel cofferdam itself.It will be useful for the construction of similar deep water and shallow overburden underwater cofferdams in the future and it has high reference and promotion value.
