%X The foundation rock mass of Sanhekou Reservoir’s arch dam was investigated according to borehole deformation tests and sonic wave tests in the geological drilling at prospecting stage. These tests revealed the deformation characteristics of foundation rock mass and obtained the correlation between borehole deformation modulus and sonic velocity. The standard for selecting the foundation excavation surface according to the drilling quick test was obtained. The elevation of foundation’s excavation surface was optimized from 501 m to 504.5 m. The rationality of this optimization scheme was verified by dam foundation excavation and deformation monitoring.
