摘　　要：介绍了一种渗流等势线测量仪,该仪器依据水电比拟原理,通过等压线测量获得渗流等势线,进而对水工建筑物地下渗流流场进行了测量。为了与实测值进行对比,我们采用MATLAB求解拉普拉斯方程,获得渗流的流函数和势函数,计算与实验所得流网吻合较好,表明水电比拟法是一种有效的渗流流场测量方法,具有十分广泛的应用前景。In this paper,an experimental device for seepage equipotential line measuring based on the principle of similarity between flow and electric field is introduced.The seepage flow field is obtained by measuring the electric field.The measured seepage flow net under a hydraulic structure is compared with the numerical simulation by solving the Laplace equation of stream function and potential function with MATLAB.The conclusion is that the electrical-hydraulic analogy method is a useful theory for seepage flow field measuring and have broad application prospects.
