双排钢板桩围堰结构深水桥墩施工及数值模拟分析

Construction of Deep Water Pier of Double-row Steel Sheet Piles Cofferdam and Numerical Simulation Analysis

以贵广铁路思贤窖特大桥主桥墩深水围堰施工为例,详细介绍双排钢板桩围堰的结构设计、数值模拟分析思路,并将数值模拟分析结果与现场监控数据相对比,提出了双排钢板桩围堰的设计与施工监控要点。实践证明,采用所述技术取得了良好效果。

Taking the Sixianjiao extra-large bridge pier cofferdam construction of the Guiguang Railway for example, this paper introduces the structural design and numerical simulation analysis of the double-row steel sheet piles cofferdam structure. By means of simulation results comparing with the practical monitoring data, it proposes the key points of the design and construction monitoring. Practice shows that good effect is obtained with the mentioned technology.
