抄録

In surveying the permeability of dam foundations, Lugeon water test is usually adopted and the permeability is evaluated by Lugeon value (Lu). The curve between pressure and rate of water injection (p-q curve) is drawn by using the test results and Lugeon value is obtained from the slope of straight line part of p-q curve. However, quite a few p-q curves which have various shapes except the straight line, are obtained when Lugeon water tests are performed at fields. Therefore, in order to interpret the results of Lugeon water tests accurately the authors performs the following things: (1) p-q curves obtained from Lugeon water tests are classified into several categories, (2) causes of several p-q curves classified in (1) are summarized, (3) the methods to determine the accurate Lugeon value from each p-q curve are illustrated.
