Abstract The control of excavation deformation and reinforcement of vertical slope rock mass of the three gorges project is the key to ensure the timely impounding. Based on the analysis and demonstration of space relationship of excavation and reinforcement，and overall stability，this study solves the complex construction problems on the stability of lower bedrock blasting excavation and overhanging rock mass of the second ship lock head along north line. Through the application of advanced anchorage，individualized controlled blasting，efficient reinforcement of overhang rock mass，rapid construction of long anchor cables and concrete backfilling，the treatment scheme and engineering procedures of the overhang rock mass on the slope is proposed. The safety，high quality and high-efficiency construction of the ship lock are sure，and the ship lock is put into operation on schedule in 2003. The monitoring results show that the ship lock has been in smooth operation for 16 years. The engineering procedure proved beneficial in contributing to the avoidance of overhanging rock mass failure during construction，and have important reference significance for similar projects.
