摘要
提出了一种预测非磁性建筑物空间磁场分布的新技术.基于等效宏观磁导率和磁化率的概念,利用静磁场积分方程法的正演计算和反演计算技术,找出了试验模块磁场测量值与非磁性建筑物空间整体磁场之间的关系.通过试验模块测量和数学模型仿真相结合的手段,达到了预测低磁钢筋混凝土结构非磁性建筑物空间磁场分布的目的.
A new technique is presented to predict the space magnetic field of the non-magnetic buil-(ding.) Based on the conceptions of equivalent macroscopic permeability and susceptibility, the relation between the magnetic field of sample model and the magnetic field of the non-magnetic building is discovered by using the forward and inverse calculation of magnetostatic integral equation method. The space magnetic field of a non-magnetic prestressed concrete building is predicted by the combination of sample model measuring and mathematical simulation.
