提出了基于离散元法和神经网络的集成优化设计方法．离散元法能充分考虑边坡岩体结构的不连续性，处理边坡的大变形情况；神经网络是从实例中获取经验知识，并用之解决问题的智能系统．该方法从两条途径、不同的角度、不同的侧面来设计边坡角，并进行优化，增强了设计的可行性
An integrated optimization design method based on discrete element method and neural network is proposed. Discrete element method can give full consideration to the discontinuity of slope rock mass structure and deal with the large deformation of slope. Neural network is an intelligent system which can obtain the empirical knowledge from examples and solve the problem. The method designs the slope angle from two aspects, different angles and different sides and optimizes the feasibility of the design
