针对三峡工程永久船闸高边坡的特点，提出了随边坡开挖形成边坡岩体的质量指标、变形模量、强度等的劣化规律及估算方法。指出了通常人们研究岩石边坡时，采用不变的岩体参数进行数值分析、工程设计等，是不能反映这种情况的。采用本文研究成果对三峡工程永久船闸高边坡岩体进行非线性力学分析表明，边坡周边开挖位移与其他单位研究成果有数量级的差别（这些研究成果的最大边坡开挖位移在３ｃｍ左右）。
In view of the characteristics of the high slope of the Permanent Ship Lock in the Three Gorges Project, the deterioration rules and estimation methods of the quality index, deformation modulus, strength, etc. of the rock mass formed with slope excavation are proposed. It is pointed out that when people usually study the rock slope, numerical analysis and engineering design using invariable rock parameters cannot reflect this situation. The nonlinear mechanical analysis of the rock masses of permanent ship locks of the Three Gorges Project using the results of this study shows that the excavation displacements around the slopes are orders of magnitude different from those of other units (the maximum slope excavation displacement of these research results is about 3 cm. ).
