高拱坝抗震理论分析进展

Progress of seismic theoretical analysis for high arch dams

从高拱坝的抗震设防标准及动力稳定安全判定准则出发,对现有的高拱坝计算方法,如刚体极限平衡方法、刚体极限平衡与有限元结合方法、非连续变形分析(DDA)法、数值流形方法、界面元法、有限元-边界元-无限边界元耦合方法、随机有限元、人工透射边界和显式有限元法、并行算法,以及模型试验等进行了归纳.同时,还介绍了各种方法的优缺点.

Based on the anti-seismic standards and stability evaluation criteria of high arch dams, the current calculation methods for high arch dams are systematically summarized, which include the rigid body limit equilibrium method, method combing rigid body limit equilibrium and finite element, discontinuous deformation analysis method （DDA）, numerical manifold method, interface element method, FE-BE-IBE coupled method, stochastic finite element method, artificial transmitting boundary and explicit FEM, parallel computation and modeling test. Advantages and disadvantages of each method are also presented.
