抄録

Rock-slope slide usually develops a linear crack at the crown and is often accompanied with collapsed depression belt zone that runs parallel to the crown crack. The downstreamside subsurface bank of the belt is usually impermeable and the hydraulic pressure of the water in the belt zone works on it to cause re-sliding and often needs an immidiate measure of groundwater drainage.<br>The well hydraulics between two parallel aquifer boundaries is solved by applying the method of images. An infinite number of imaginary wells are introduced to create a hydraulic flow system which will be equivalent to the effects of the twe parallel boundaries on the flow system. Exps (9) and (10) stand for a well located at distances a1 from the line source, that is, recharging bank and b1 from the impermeable bank, while exps (19) and (20) are for a well where both of the aquifer boundaries are recharging banks.
