摘要
三峡永久船闸在山体中深切开挖修建，直立边坡高度为 ５０～７０ ｍ，边坡整体稳定条件较好，由裂隙组成的大量随机块体引起的局部稳定问题较为突出，且危害施工安全，通过深入细致地现场地质工作，按照动态设计的原则，经过对所有块体进行逐个复核计算和加固处理，其安全和稳定性得到了可靠保证。
The TGP permanent shiplock was dug and built in hill. The height of shiplock slope is 50~70 m and the unitary stability of the slope is quite good. But the problem is very serious which resulted from a mass of random wedges composed of cracks, to affect partial stability and safety of slope. After careful geological research in site, according to the principle of dynamic designs the stability and safety of the slope are insured after all wedges were checked and reinforced.
