三峡永久船闸主体段高边坡工程规模之大、技术难度之高均为国内外边坡工程所罕见，其加固处理设计是三峡工程的主要技术难题之一。在设计中，按照满足结构布置要求和使边坡岩体达到基本自稳进行开挖，以截、防、排水措施为主，以锚固支护措施为辅进行加固支护，排水与锚固根据施工地质和监测资料进行动态优化，通过充分排水和合理开挖解决边坡整体稳定问题，通过喷混凝土锚固支护解决边坡局部稳定问题。
The high slope of the main section of the permanent ship lock of the Three Gorges Project is large in scale and difficult in technology. It is rare for slope engineering at home and abroad. The reinforcement design is one of the major technical problems of the Three Gorges Project. In the design, according to the requirements of structural arrangement and excavation, the rock mass of the slope has reached the basic self-stability, excavation should be carried out with the measures of cutting, preventing and draining. The anchoring and supporting measures should be supplemented to reinforce and support, drainage and anchoring. According to the construction Geology and monitoring data to optimize the stability of the slope through full drainage and reasonable excavation, and to solve the problem of local stability of the slope by sprayed concrete anchoring support.
