| 摘 要： | 依托长兴一期造船基地某大型干船坞工程,基于船坞基坑工程的设计特点和施工经验,建立三维有限元整体模型,对超大面积船坞工程时空效应和变形特性进行有限元分析。提出施工中预留部分土体和坞墩对坞墙钢板桩形成约束后开挖预留土体的两项措施,可对坞室基坑开挖时的变形加以控制。

| Abstract: | Based on the design data and construction experience of CSSC Changxing shipbuilding base,we establish a 3D finite element model to analyze space-time effect and deformation characteristics of large paratactic dock.We propose reserving partial soil mass before building ground floor and excavating the reserved parts after dock wall steel sheet pile,which can control deformation of dock chamber foundation excavation. |
