For Qingping Reservoir Water Supply Project,several methods were adopted to inspect the mechanical properties,impermeability and compactness of main dam roc-fill concrete,including cube compressive test,drill-ing core method,direct shear test of concrete bloc-,ultrasonic test and underground visual TV test. The results of inspection conform to relevant design specifications with the compressive strengths of 17.4MPa and 35.2MPa for self-compacting concrete and core sample respectively,a friction factor of 1.051,a cohesive force of 0.124 and im-permeability grade of W4. Ultrasonic test and underground visual TV test are both effective methods for roc-fill con-crete compactness inspection.
