摘要
针对万家口子双曲拱坝的地质问题,采用三维地质力学模型试验技术,全面模拟了大坝基础的不连续岩体条件、岩石力学性质、基础处理和整体双曲拱坝,研究了基础对大坝结构变形和稳定的影响,揭示拱坝坝体和坝肩从加荷开始到破坏的整个进程和机理,从而得出了拱坝的破坏机理及超载安全能力。
With respect to geologic problems of the Wanjiakouzi double-curvature arch dam,3D geomechanical model test is done to simulate the discontinuous rock mass of the dam foundation,mechanical properties of rock,foundation treatment and the whole dam.The impact of the foundation on structure deformation and stability of the dam is studied,and the whole process and mechanism of the dam and its abutments from the beginning of loading to the model＇s failure are displayed.As a result,the failure mechanism and the safety against overloading of the dam are learnt.
