Monitoring Technology of High Precision Drilling in Nanyi Dam

摘要：

With the features of narrow gallery and the hard bedrock in Nanyi dam, the effective borehole radius and declining gradient of borehole meet the design requirement with choosing the appropriate equipment and adjusting the appropriate drilling parameter of the equipment,adopting the appropriate construction technique and correcting method for inclination. The experience can be applied to similar projects.
