摘要
主要介绍采用Marc软件求解节制闸在上下游水位变化下的整体空间位移和主应力,采用程序提供的接触分析功能,对构造节制闸、灌注桩和地基结构的三维有限元模型来进行计算分析,直观可靠地得出整体结构的位移场和应力场,判断其整体强度和稳定性,并对其工作性态进行评价。实例分析表明,三维有限元分析结果能较直观、精确反映建筑物整体强度与位移状况。
It is mainly introduced here how to use the software of Marc to calculate the displacement and stress of the sluice when the water-level changes between upstream and downstream.And the function of contact analysis provided by the program is used to construct the finite element model which concludes the sluice,piles and foundation for calculation and analysis.So the displacement and stress of the massive structure will be worked out to estimate its whole stability and evaluate its workability state.The examples show that the results of three-dimansional finite element analysis could be used to accurately reflect the state of overall strength and displacement of the buildings.
