三峡永久船闸岩石高边坡工程稳定技术

STABILIZATION TECHNOLOGY ON THE HIGH-STEEP ROCK SLOPE IN THE THREE GORGES PROJECT SHIPLOCK

在阐述船闸高边坡工程特点的基础上，论述了该工程实施的技术路线，并重点介绍了工程规模、岩体支护、防渗排水、施工程序与爆破控制和监控技术，最后得出了施工期边坡总体和局部稳定、总体变形基本控制在预计范围内的结论。

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.
