摘要
依托长兴一期造船基地某大型干船坞工程,针对船坞基坑工程的设计和施工特点,建立二维有限元模型。分析有限元模型的影响因素,对船坞基坑开挖变形特征进行研究。指出模型选用接触效应、考虑船坞廊道底部桩基和船坞底板桩基的必要性,并阐述预加拉杆拉力对控制船坞变形的有利作用。
Based on the design data and construction experience of CSSC Changxing shipbuilding base, we establish a 2D finite element model to analyze the influential factors for deformation during excavation of dock foundation pit. The result shows that choosing exposure effect and taking the foundation of both bed plate and corridor bottom of the dock are necessary in this model, and pre-adding tension force of the bar is beneficial to controlling of anchorage＇s structural deformation.
