【摘要】 电容层析成像技术(ECT)在化工、油气等领域已是一种相对成熟的观测和研究技术,但目前还未正式用于水文地质勘察领域。首先介绍了ECT的基本原理,并对ECT系统进行精简改造,然后进行室内实验探测水体中的异常体。同时,利用有限元软件ANSYS和MATLAB进行相应的模拟实验,并对用模拟和实验得到的电容值进行反演成像。模拟和室内实验结果表明,改造后的ECT系统能够准确探测出水体中的异常体,这对ECT用于水文地质勘察研究有很好的探索意义。更多还原

【Abstract】 Electrical Capacitance Tomography(ECT) has been developed as a mature technique for monitoring and researches in chemistry and petroleum industries,however nowadays it has not been applied in hydrogeological fields.Firstly the principles of ECT are presented in this paper.Then an ECT system is modified to perform the experiment of probing anomalous bodies in water in laboratory.In addition,ANSYS(a finite element analysis software) and MATLAB are employed to a simulation experiment.The capacitances obtained from the simulation and experiments are used to image reconstructions.The results of the simulation and laboratory experiments reveal that the modified ECT system is capable of probing anomalous bodies in water accurately,which is of a great significance for application of ECT in hydrogeological exploration and researches.更多还原
