摘　　要：探讨高速铁路变形监测信息的可视化表达应用。将BIM虚拟技术与高速铁路变形监测信息融合,利用Multi-Quadric径向函数,对监测数据进行插值计算,构建铁路变形监测的信息模式,获得监测信息节点的物理量值。在融合距离映射法获得变形监测信息竞争层神经元和输入模式矢量的相似度,将输入矢量降维,并映射到二维平面,完成对铁路变形信息的可视化动态监测。仿真结果显示,BIM虚拟技术的精准度、可靠性符合实践要求,优于传统动态监测算法。因此,BIM虚拟技术可以对高速铁路变形信息进行准确的动态监测。The application of visual expression for deformation monitoring information of high-speed railway is discussed.The BIM virtual technology and deformation monitoring information of high-speed railway are fused,and the difference of monitoring data is calculated by using multi-Quadric radial function.The information model of railway deformation monitoring is constructed,and the physical value of monitoring information node is obtained.The similarity between neurons and input pattern vectors in the competition layer of deformation monitoring information is obtained by fusing the distance mapping method.The input vectors are reduced in dimension and mapped to two-dimensional plane to complete the visual dynamic monitoring of railway deformation information.The simulation results show that the precision and reliability of BIM virtual technology meet the practical requirements,and it is superior to the traditional dynamic monitoring algorithm.Therefore,BIM virtual technology can accurately and dynamically monitor the deformation information of high-speed railway.
