摘要
为研究古遗址保护建筑斜柱支撑系统在整个施工过程中的受力影响因素,保证洛阳应天门遗址东朵楼结构施工安全,采用MIDAS Gen软件建立了东朵楼三维有限元模型,考虑土压力、自重、施工荷载等,按设计施工顺序,面向施工全过程进行仿真分析,研究施工过程中的斜柱支撑系统结构应力及变形的变化规律。实测与数值计算结果分析表明:遗址原土堆载的影响不容忽视,考虑其影响的模型相对合理,模拟结果与实测的结果较接近,斜柱支撑系统应力及变形趋势基本相同,建议优化桩土相互作用分析步骤。
In order to study the influence of the support system of inclined column in the whole construction process of ancient site protection building and ensure the construction safety of Dongduo building in Luoyang Yingtianmen site,a three-dimensional finite element model of Dongduo building was established by MIDAS Gen.Considering the earth pressure,deadweight and construction load,according to the order of design and construction,the simulation analysis of the whole construction process was carried out,and the variation law of stress and deformation of inclined column bracing system during construction was studied.The analysis of the measured and calculated results showed that the influence of the original soil load on the site could not be ignored,the model considering its effect was relatively reasonable,the simulation results were close to the measured results,and the stress and deformation trends of the inclined column bracing system were basically the same.It was suggested to optimize the analysis procedure of pile-soil interaction.
