摘要: 利用自行开发研制的试验平台,基于大量实验室岩石楔块滑落试验结果,提出了极限平衡状态时楔块滑落与否的判别新准则.通过对楔块滑落过程及其极限平衡状态的研究,得到不同条件下描述楔块滑落状态的β-α(倾斜角-旋转角)关系曲线的函数方程.定量分析了岩体结构面参数(产状、粗糙度系数JRC)对所提函数方程中相关系数取值的影响,给出了利用楔块粗糙度系数JRC与结构面交角ω求β-α函数方程的方法.

关键词: 岩体结构, 滑落, 极限平衡, 试验分析, 判别方法

Abstract: A self-developed test platform was used to conduct a large number of rock wedge sliding experiments, based on which a distinguishing criterion of limit equilibrium state to judge whether the wedges slide or not was put forward. The wedges sliding process and its limit equilibrium state were studied to get the beta-alpha equation (relation between inclination and rotation angle) under different condition. The effects of rock structural plane parameters (occurrence, roughness coefficient JRC) on the correlation coefficient of the proposed function equation were quantitatively analyzed, with the beta-alpha equation given by using the known slider roughness coefficient JRC and structural plane angle ω.

Key words: rock mass structure, sliding, limit equilibrium, experimental analysis, discrimination method
