摘要
介绍了复杂电阻率分布的机敏混凝土CFRC(C arbon F iber R e in forced Concrete)结构电阻率层析成像ERT(E lectrica l R es istance T om ography)FEM数值投影方法。结合VC和AN SY S的优点以及APDL程序生成技术,根据CFRC结构电阻率分布图像和孔洞形式建立了各种ERT模型的FEM分析模型,进而获得它们的ERT数值投影数据。给出了2种复杂电阻率分布ERT模型的数值投影结果。
A numerical FEM projection method in ERT for CFRC structure with complex resistivity distribution is introduced. Combined with the advantages of VC＋ ＋ and ANSYS and APDL program generation technology, the FEM model for ERT projection is easily established. The FEM mesh is divided automatically according to the holes shape of ERT model. And the resistivity of FEM elements is easily assigned according to the image that describes the complex resistivity distribution of the CFRC structure. So the projection data of ERT model can be obtained. Finally the results of two ERT models with complex resistivity distribution are given.
