摘　　要：船闸高边坡是三峡工程的重要建筑物之一，是船闸结构的组成部分。达到足够的稳定，控制适量的变形，确定合理的开挖形态和进行恰当的加固支护是船闸高边坡工程系统研究中应解决的主要问题。经过近２０年的大量试验研究工作，论证了边坡总体稳定性好，变形不会影响运行，并确定了满足船闸结构布置要求的边坡形态和以截、防、排水措施为主，岩锚支护为辅的边坡加固方案。The high excavated rock slope is an important feature of the TGP shiplock structures. To achieve sufficient stability, to control deformation in appropriate limit, to draft reasonable excavation shape, and to strengthen and support the slope in a proper way are major subjects to be solved in the shiplock high excavated slope engineering. Through large amount of experiments and investigations for nearly 20 years, it is demonstrated that the stability of the entire slope is sufficient and the deformation will not influenec the operation of the shiplocks. Accordingly, the slope shape, which meets the requirement of the shiplock structure layout, and the slope strengthening scheme, which takes the seepage interception, prevention and drainage as major measures and rock bolt support as auxiliary measure, are determined.
