摘要
用地质力学模型试验方法，在实验室对层状岩体边坡进行分期开挖破坏试验，同时利用考虑了岩层弯曲变形效应的有限元程序模拟开挖破坏过程。两种方法所得结果具有良好的可比性，揭示了在开挖状态下岩体弯曲变形折断破坏的一些规律。
A kind of geo model material is used to model the slope with layered rockmass. By multi stage excavation of the slope, the damage process is checked. In the meantime, the FEM with consideration of the bending effects of the rocklayers is used in the model of damage process. The results from the two methods are well coincident, and disclose some bending damage regularities.
