摘要
基于弹性地基梁原理,采用有限元软件ANSYS,建立龙门吊轨道基础与弹性地基相互作用的模型,得到模型在吊车移动荷载作用下的内力及基底压力的包络图,并对有伸缩缝和无伸缩缝时的两种情况进行了对比分析,得到了有益的结论,对后续的基础设计工作有重要指导作用。
Based on the relevant theories of elastic foundation beam,FEM software ANSYS was used to set up the model of portal crune track foundation-elastic soil interaction,by which internal force and foundation pressure envelopes of the model with moving loads were presented. Meanwhile,two circumstances of crane track foundation with and without expansion joint were also compared. Some useful conclusions were given to guide the detailing design of foundations.
