| 摘 要： | 三峡永久船闸两线闸室间保留岩体隔墩方案因比全挖后回填混凝土方案经济而予采用，使得对保留岩体的加固成为一个关键问题。施工中遇到的中隔墩表层岩体裂缝、直立墙顶几何滑移块体等岩石力学问题通过现场动态设计，分别制定了详细的工程处理对策，大量监测数据表明，中隔墩的岩体利用与加固是成功和安全的。

| Abstract: | The reserved rock mass between two lines of TGP permanent ship lock is used as their division pier, which is obviously superior in economy to the scheme of removing the rock mass and constructing a concrete division pier at its location. The rock mechanics problems encountered in the course of excavating the lock chambers, such as cracking on the surface of reserved rock masse the potential movable rock blacks on the top of vertical excavated wall, and the large faults, were all salved through engineering treatment measures developed by field dynamic designs and the reserved rock mass is strengthened. |
