摘要
阿海水电站坝基下伏地层主要为泥盆系浅变质岩和后期顺层侵入的辉绿岩条带,地质条件复杂,各向异性明显。本文通过材料力学法、平面有限元法和三维有限元法对大坝和坝基进行分析,研究复杂层状岩体坝基的建高坝适应性,并提出相应的坝基处理措施,为类似工程的设计提供参考与借鉴。
The stratum of foundation of A Hai hydropower station is mainly devonian system metamorphic rock and diabase swath which is concordant intrusion afterwards, geologic setting is complex and with distinct anisotropism. The paper analyses the dam and its foundation by mechanics of materials, 2D and 3D FEM methods, and studies high dam construction adaptability on complex Stratification foundation which can be used for similar project reference.
