摘要

岩体蠕变参数是岩土工程设计必不可少的重要资料，为准确确定岩体的蠕变力学参数，综合考虑解析反演法和智能反演法的优点，将这两种反演方法耦合，建立了岩体蠕变参数的解析-智能反演方法，将这种方法应用到大岗山水电站工程中，解析智能反演获得坝区岩体的压缩蠕变参数。计算结果表明：解析-智能反演蠕变曲线与试验蠕变曲线的拟合程度比解析反演蠕变曲线与试验蠕变曲线的拟合程度好，说明解析-智能反演法获得的坝区岩体蠕变参数更为准确可靠，同时也验证了这种参数反演方法的有效性和合理性。该方法为高效快捷地反演坝区岩体的蠕变参数提供了重要理论指导。

Abstract

The creep parameters of rockmass are essential data of geotechnical engineering design. To accurately determine the creep mechanical parameters of rockmass

considering the advantages of the analytical inversion method and intelligent inversion method

the analytical intelligence inversion method coupling the analytical inversion and the intelligent inversion is developed. The proposed method is applied to the Dagangshan hydropower station project to obtain the compressive creep parameters of rockmass in dam zone. The results show that analytical intelligence inversion creep curves are more coincident with experimental creep curves than the analytical inversion creep curves

proving that the creep parameters obtained through the analytical intelligence inversion method to be more accurate and reliable

and hence the validity and rationality of this inversion method are also verified. The method provides an important theoretical guidance for efficient rheological parameters inversion of rockmass in dam area.
