Hoek-Brown经验强度准则具有能够反应岩体的固有特点和非线性破坏特征，解释低应力、拉应力区及最小主应力对强度的影响等特点，已成为岩体工程中应用最广泛的准则之一。但是，在确定Hoek-Brown准则参数时主观因素影响较大。分析了Hoek-Brown准则中完整岩石经验常数mi、完整岩体单轴抗压强度σci、地质强度指标GSI、岩体弱化因子D等参数对内摩擦角φ、粘聚力c以及边坡安全系数F影响的敏感性，以期对Hoek-Brown准则参数取值提供帮助。

The Hoek-Brown strength criterion has become one of the most widely used criterions in rock engineering because it can reflect the inherent characteristics and nonlinear damage characteristics of rock, explain the effect of low stress area, tensile stress area and minimum principal stress on strength. Since the subjective factors have a great influence on determining the Hoek-Brown criterion parameters, the sensitivity of Hoek-Brown criterion parameters are analyzed, including the parameters of mi, σci, GSI and D to internal friction angle φ, cohesion c and slope safety factor F, to provide some references for determining the parameters of Hoek-Brown criterion.
