STABILIZATION TECHNOLOGY ON THE HIGH-STEEP ROCK SLOPE IN THE THREE GORGES PROJECT SHIPLOCK
三峡永久船闸岩石高边坡工程稳定技术

The permanent shiplock is one of the main structures of TGP. The stability and deformation control of the shiplock slope are the key technical problems of the TGP. According to the characteristics of the slope, the technical path is discussed for the research, design and construction, and then the slope scale, rock support, drainage and seepage-prevention, construction procedures, blast control and monitoring measures during construction are presented. The conclusion is that the stability and deformation up to now have been controlled in the range of design.
