基于Hoek－Brown强度准则提出了一种岩石抗压强度测井解释的新方法，根据岩石力学性质定义的参数均具有明确物理含义和取值范围，利用最小二乘法对所定义参数进行赋值，寻求所定义参数与波阻抗之间的关系，最后建立考虑泥质含量实际地层条件下岩石抗压强度测井解释模型。该方法不仅考虑了岩石的声波及物性（如密度）的变化，同时暗含了岩石在各级围压条件下破坏强度变化的信息，因而相比常规测井解释有所改进。该方法能较全面反映岩石在地层条件下破坏强度变化规律，根据力学特征定义的参数赋值可信，最终将模型计算值与实测值及常规测井解释结果进行对比，误差较小，能够满足工程需要。

Rock compressive strength presents important rock mechanics properties under the geological condi-tions.This strength can be used to calculate the tensile strength,study the tunneling and affect the engineering safety,which has close relationship with stress field simulation.A new interpretation method based on Hoek-Brown strength criterion is proposed.Parameters defined by the rock mechanics properties have clear physical meaning.By using the least squares method to define the proposed parameters,the relationship between defined parameters and the wave impedance is found.Finally rock formation compressive strength logging interpretation model considering argillaceous content is established.By comparing the calculated values with the measured val-ues,it shows that the error is small and can satisfy the needs of engineering.A new way for the underground rock compressive strength continuous logging interpretation is provided.
