RESULTS AND ANALYSISES OF IN-SITU SEEPAGE TESTS IN FAULT ZONES OF DAM FOUNDATION ROCKMASSES IN XILUODU HYDROELECTRIC STATION
溪洛渡水电站坝基层内错动带现场渗透变形试验成果及分析

The fault zones consist of main discontinuities with low dip angle in the dam foundation rockmasses of Xiluodu hydroelectric station. Therefore,investigating the characteristic of seepage in fault zones can instruct the design of impervious curtain in the dam foundation. The in-situ seepage tests in fault zones and their results are introduced. The factors affecting the permeability,critical gradient,failure gradient and the procedure of seepage are analyzed.
