摘　　要：三峡工程永久船闸闸室段左右线之间备受关注的岩体中隔墩曾在直立坡开挖仅十几米的情况下,其顶面找平砼就出现了裂缝,且随后似有逐渐增多之势,一时,中隔墩能否稳定受到众多质疑,亦立即引起了众多岩体力学专家和有关决策者的高度关注。为此,长江水利委员会进行了专项研究。作者为该项目地质负责人之一,从岩体的变形特征、找平砼裂缝的发育特征、卸荷松弛带岩体的性状等方面综合阐述并科学地评价了中隔墩岩体的稳定性。When the upright slope of the separate mound rock of the permanent shiplock of the Three Gorges project was digged only for a dozen of meters, some cracks were found on the surface of the separate mound, and the number of cracks seemed increasing gradually afterwards. For the moment, it was doubtful whether the mound rock could keep stable, it attracted attention from many experts and some decision - makers at once. For this reason, CWRC went through this study. The authors were one of the leaders. According to the deformation characteristic of the rock, the crack distributing characteristic on the surface of the separate mount rock, and the unloading characteristic of the rock, a scientifical appraisal of the separate mound rock＇s stability had been made.
