Abstract: The conductivity of Wayazui Spring is obviously disturbed by ground digging and cement pouring while a house is built at head waters of Wayazui Spring 380 maway, which can also be regarded as a hydrogeology experiment.The seepage velocity of Wayazui Spring's crevassed aquifer is calculated according to contrast analysis between the time of building works and the disturbance of the Spring's conductivity.The seepage coefficient of Wayazui Spring's crevassed aquifer is roughly calculated according to the topography elevation and the waterhead altitude of the crevassed aquifer.
