| 摘 要： | 西南某坝区右岸由海西期花岗岩组成。除断裂构造发育外，右岸岩体蚀变类型多，分布广，风化和卸荷强烈，深度大。上述现象组合在一起，使右岸岩体极为复杂。实地调查表明，这一复杂岩体的形成主要是由于右岸丫口后山穹隆新生代以来曾经经历过较强烈隆升导致放射状和环状张裂隙发育的结果。

| Abstract: | The right bank of a hydropower dam,located in the Southwest of China,is composed of upper Paleozoic granite. Besides the faults developed in the rock mass, deferent kinds of erosion,weathering and unloading are widely spread,producing the complicated rockmass conditions in the right bank.The investigations have shown that it resulted from the quick uplifting of Yakouhoushan vault since Cenozoic and subsequently induced formation of radiated and circular fissures. |
