摘要: 从地貌学角度分析了三峡工程永久船闸边坡岩体的自然及人为卸荷特性.指出了地表侵蚀,河流下切及人为开挖船闸等自然及人为地貌过程诱发了岩体的基本卸荷过程,构筑了一个三峡工程永久船闸边坡岩体卸荷特性的宏观模式.实地调研及数值计算成果均表明,地貌分析法在分析实际岩体工程中岩体卸荷的宏观特性方面具有较强的应用价值.

Abstract: On the view point of geomorphology, natural and artificial unloading features of rockm ass slope in the permanent shiplock of the Three Gorges Project are approached in this paper, which shows that geomorphologic processes, e.g.ground erosion, cutting of the Yangtze River and artificial cutting of the shiplock, etc.have been inducing general unloading features of rockmass in the slope.Macrofeatures of rockmass unloading are outlined in geomorphologic method in the paper.As the model is consistent with characteristics insitu and numeric calculation, it is valuable for geomorphologic analysisth be used in general studies on unloading of concrete rockmass engineering.

Key words: the Three Gorges Project, permanent shiplock, geomorphologic analysis method, unloading, rockmass fracture
