接收函数与重力联合估计的技术与应用研究进展

Advances in techniques and applications of joint estimation by receiver function and gravity data

  • 摘要: 接收函数与重力联合估计技术是一种估计地壳厚度和波速比参数的方法,自2011年由Lowry和Pérez-Gussinyé提出以来,经过国内外学者的发展和改进,该方法已日渐成熟,应用领域渐广. 与单一接收函数H-κ叠加法相比,该方法由于引入了重力约束,可以在一定程度上降低估计的不确定性,获取台站下方更为准确的地壳厚度与波速比参数,为研究地壳结构与物质组成提供更为可靠的深部依据. 本文首先简述了单一接收函数H-κ叠加法和重力似然函数估计的方法原理,并详细介绍了接收函数与重力联合估计技术的算法与流程;其次,剖析了该方法目前存在的一些技术问题,重点阐述了其相应的技术发展和各项优化;然后,归纳总结了该方法在国内外地区的应用进展;最后,展望了该方法未来的研究方向和发展趋势.

     

    Abstract: The joint inversion of receiver function and gravity data estimates the crustal thickness and VP/VS ratio. Since Lowry and Pérez-Gussinyé proposed it in 2011, this joint inversion method has been improved and refined by domestic and international scholars, and gradually applied in various fields. Compared to the traditional receiver function H-κ stacking technique, this method minimizes the uncertainty of results by including a gravity constraint and provides more accurate values of crustal thickness and VP/VS ratio. It also provides more reliable evidence for studying the crustal structure and material composition. This paper first introduces the principle of receiver function H-κ stacking technique, gravity likelihood function estimation, and the algorithm/flow of joint inversion of receiver function and gravity data. Then we analyze its current research efforts, potential technological issues, and corresponding improvements. In addition, the present application of this method in domestic and foreign areas is introduced. Finally, we discuss the further research direction and development trend of the technique.
