摘要
三峡工程船闸高边坡变形监测资料表明，岩体变形主要受开挖卸荷影响，边坡岩体卸荷松弛特征明显，具有 分带性。微风化新鲜岩体变形主要是沿结构面张开实现的，从而引起岩面找平混凝土或喷护混凝土开裂。岩体变形 大小与变化过程还与地质条件、施工爆破、锚固等因素有关。
The deformation monitoring results of high rock slope of the Three Gorges Project shiplock show that the deformation of rock mass which is identified as 3 different zones obviously is mainly caused by excavation and unloading of ground stress. The deformation of the fresh and slightly weathered rock mass is achieved by the opening of joints, which causes the cracking of surface concrete and shotcret. The range and process of the rock mass deformation are related to the geological conditions, blasting, and cable anchoring.
