摘要

对上海某大型船坞工程双排钢板桩围堰进行现场监测，并结合施工工况对监测结果进行分析，对大跨度双排钢板桩围堰的变形特性进行研究．监测结果表明，大跨度双排钢板桩围堰的变形较大，且具有明显的三维空间效应，围堰前、后排钢板桩的变形特性存在一定差异．利用考虑应力场与渗流场完全耦合的有限元方法模拟现场施工情况，分析了现场施工中加固围堰内侧土体对控制围堰变形的效果．

Abstract

Large span double-row steel sheet piles were constructed in marine environments to serve as cofferdams of dry dock projects. Due to the construction of the dock excavation, considerable deformation of the cofferdam could occur. The deformation of the large span double-row steel sheet piles was measured during construction of a large scale dock project in Shanghai. Extensive field performance data were collected including lateral survey data and lateral inclinometer data. Construction procedures were summarized and correlated with monitoring data. The measured data were analyzed to investigate the deformation performance of the large span double-row steel sheet piles. A 2D finite-element method was also performed to study the effect of the soil reinforcement technology on deformation control of the double-row steel sheet piles.

Key words： large span double-row steel sheet piles; cofferdam; deformation performance; field observation; finite-element method
