S412: the potential data of gathering is placed on the measuring point coordinate corresponding in the coordinate system.
S413: draw the current potential isogram, determine geomembrane leak position.Concrete grammar is:
As mentioned above, near leak position or lower floor's conductive filament during near the leak position, measured potential data all shows as maximum value, will show as the exceptional value of symmetrical distribution on the current potential isogram at the upper strata conductive filament.Therefore, coordinate and corresponding potential data according to the point of crossing are drawn the current potential isogram, analyze the distribution characteristics in current potential positive anomaly zone on the isogram, and mark the center in symmetrical distribution current potential positive anomaly zone, then this center is geomembrane leak position.Can be with reference to equivalent curve figure shown in Figure 4.
S414: testing process finishes.
Fig. 4 shows the equivalent curve figure of the measurement current potential that the detection method of application drawing 3 embodiment obtains.
In Fig. 4, solid black point is the position of the actual leak of geomembrane, and hollow circle institute area surrounded is the current potential positive anomaly zone of current potential isogram.As can be seen from Figure 4, the center of empty circles and the position of actual leak can coincide substantially, and the position of leak position and each measuring point all can utilize horizontal ordinate and ordinate in the coordinate system to determine.
