摘　　要：岩石弹性参数的准确测量对于地下资源的可靠评价和勘探开发具有重要意义。超声共振谱法基于共振频率与岩石弹性性质相关的原理,较传统方法如超声脉冲穿透法、应力应变法等,具有可重复测量、测量精度高、一次测量可获得全部弹性参数的优点,并且可用于不规则样品的测量,因此在岩石弹性参数测量方面拥有广阔的应用前景。该文主要综述了20世纪60年代以来超声共振谱方法的测量、正演方法和反演方法的发展历程,并分析了样品制备、测量方式和计算方法等因素对测量结果的影响,最后对近些年来该方法在测量方法、正演方法、反演方法、非线性测量及极端环境下的测量等方面的进展进行了总结及展望,对未来应重点关注的方向给出了建议,以期对于常规岩石以及页岩和海底矿物等非常规岩石的弹性参数测量方法的发展提供帮助。Accurately measuring the elastic parameters of rocks is crucial for reliable evaluation and exploration of underground resources.Resonant ultrasound spectroscopy is based on the principle that resonant frequency is related to the elastic properties of rocks and offers several advantages over traditional methods,such as ultrasonic pulse transmission and stress-strain method.These include repeatability,high measurement accuracy,and the ability to obtain all elastic parameters in one measurement.It can also measure irregular samples,making it a promising method for measuring rock elastic parameters.This paper reviews the development of resonant ultrasound spectroscopy method,including forward and inverse methods since the 1960s,and analyzes the influence factors such as sample preparation,measurement methods,and calculation methods on measurement results.Finally,recent progress and prospects in measurement,forward and inverse methods,nonlinear measurement, and measurement in extreme environments are summarized. Suggestions for futureresearch directions are provided to help develop elastic parameter measurement methods for conventionalrocks, shale, seafloor minerals, and other unconventional rocks. Suggestions are given for future directions thatshould be focused on and expected to benefit the development of elastic parameter measurement methods forconventional rocks as well as unconventional rocks such as shale and seabed minerals.
