单层钢板桩深水围堰施工技术

九华河大桥水中墩的施工过程中采用单层钢板桩进行水下围堰施工，结合工程的实际情况，对单层钢板桩稳定性、涌砂隆起进行了验算，确定了单层钢板桩的设计参数，并对施工过程中钢板桩的受力大小以及封底层厚度进行了计算，为施工提供了可靠依据。施工过程的监测数据表明，该单层钢板桩设计合理，结构稳定，保证了工程的顺利进行，为以后类似工程施工提供了较大的参考价值。

Construction Techniques for Single-layered Steel-plate Pile Cofferdams in Deep Water

During the construction of the piers of the Jiuhuahe Bridge,single-layered steel plates were used for the construction of the underwater cofferdam.With the project as a practical example,the stability of the single-layered steel-plate piles,and the piling of the flushing sand are examined and calculated so as to determine the design parameters,with the forces exerted on the steel-plate piles,and the sealed depth of the bottom calculated so as to provide a solid basis for the construction.The monitored data ...
