COMPARISON OF RESULTS OF CONVENTIONAL AND HIGH PRESSURE WATER-PRESSURE TESTS ON THE DAM FOUNDATION ROCK MASSES OF XILUODU HYDROELECTRIC STATION
溪洛渡水电站坝基岩体钻孔常规压水与高压压水试验成果比较

The comparison of results of conventional and high pressure water-pressure tests on the dam foundation rock masses of Xiluodu hydroelectric station is performed in order to determine the change of permeability of rock masses under different stresses. The changes of Lugeon unit and P-Q curve are achieved according to the results of comparison tests.
