基于建筑物移位工程的数字化和可视化模拟

沉降差对迁移建筑物的受力影响较大，而国内缺少这方面的模拟分析．通过将迁移轨道沉降差的变化转化为一系列数字，并利用算法把数字的变化转化为顶升缸顶升力的变化，模拟了不同迁移路面情况对迁移建筑物受力的影响．为了对迁移工程的可靠性和经济性进行预判，同时更好地利用数字化分析结果指导实践，通过VC＋＋读取ANSYS结果文件在OpenGL上实现了建筑物迁移的可视化模拟．仿真结果与工程实践吻合，可为以后的施工决策提供依据．

Simulation of Digitalization and Visualization Based on Building Moving Project

Differential settlement has a great influence on the suffered force of moving buildings, but there were Iew domestic researches on its simulation. By translating the differential settlement changes of track to a series of numbers and then translating the number changes to lifting force fluctuation of hydraulic cylinders, the influences of different road conditions on the suffered force of moving buildings were simulated. In order to predict the reliability and economic efficiency of the relocation project and meanwhile make better use of digital analysis results to guide practice, a virtual simulation system of monolithic relocation was realized on OpenGL by using VC＋＋ to read the output files of ANSYS. The simulation results were very close to engineering practice, which can offer a reliable basis for future decision-makings in construction.
