超大型结构物建造过程中滑道受力的建模分析

摘要

Very large-scale structures are influenced by various factors in construction. In particular, the supporting point pressure and arrangement of lift-up equipment have strong influence on the structures which need to be lifted up and its slide way. Therefore, we apply Drucker-Prager Plasticity Rule in establishing finite element model of slide way and earthwork as a whole, systematically analyze the pile foundation supporting slide way No.5 of Qingdao Offshore Engineering Base, and calculate the stress and sedimentation of slide way in the construction of large-scale structures, which will guarantee the project construction technically.%在建造过程中超大型结构物会受到多种因素的影响,特别是需要顶升的结构物,顶升装置的布置和支点受力情况将在很大程度上影响滑道和结构物的安全.采用Drueker-Prager Plasticity准则建立滑道和土的整体有限元模型,对青岛海洋工程基地5#滑道的桩基础进行系统分析,计算大型结构物建造过程中的滑道受力和沉降,为工程建设提供技术保障.
