Anti-dip layered rock slope is a common type of slope in hydropower engineering. Its stability is controlled by slope geometry, rock characteristics and structural plane properties. To reveal the influence of multiple factors on the stability of such slopes, taking the safety factor and displacement as dependent variables, the significance of six main factors, namely slope angle, slope height, rock inclination angle, rock thickness, rock quality and structural plane quality, was studied based on the approaches of discrete element modelling and orthogonal test design. Moreover, the deformation and failure laws of typical modes for anti-dip slopes were analyzed. The study can provide a reference for the optimal design of anti-dip layered rock slopes.

反倾层状岩质边坡是水电工程常见的一种边坡类型,其稳定性受控于边坡形态、岩体特征和结构面性质等因素。为了揭示不同因素对此类边坡稳定性的影响程度,基于离散元数值计算模型,运用正交试验设计方法,分别以安全系数和关键点位移为目标变量,研究了坡角、坡高、岩层倾角、岩层厚度、岩体质量和结构面质量等6个主要因子对边坡稳定性影响的敏感程度,并剖析了反倾边坡典型失稳模式的变形和破坏规律。研究结果可为反倾层状岩质边坡的优化设计提供参考依据。

反倾层状岩质边坡是水电工程常见的一种边坡类型,其稳定性受控于边坡形态、岩体特征和结构面性质等因素。为了揭示不同因素对此类边坡稳定性的影响程度,基于离散元数值计算模型,运用正交试验设计方法,分别以安全系数和关键点位移为目标变量,研究了坡角、坡高、岩层倾角、岩层厚度、岩体质量和结构面质量等6个主要因子对边坡稳定性影响的敏感程度,并剖析了反倾边坡典型失稳模式的变形和破坏规律。研究结果可为反倾层状岩质边坡的优化设计提供参考依据。

Anti-dip layered rock slope is a common type of slope in hydropower engineering. Its stability is controlled by slope geometry, rock characteristics and structural plane properties. To reveal the influence of multiple factors on the stability of such slopes, taking the safety factor and displacement as dependent variables, the significance of six main factors, namely slope angle, slope height, rock inclination angle, rock thickness, rock quality and structural plane quality, was studied based on the approaches of discrete element modelling and orthogonal test design. Moreover, the deformation and failure laws of typical modes for anti-dip slopes were analyzed. The study can provide a reference for the optimal design of anti-dip layered rock slopes.
