PEELING GENETIC ALGORITHM OF RECEIVER FUNCTIONS INVERSION FOR UPPER MANTLE STRUCTURE AND DISCONTINUITIES
接收函数反演上地幔速度结构和间断面的剥壳遗传算法

To study the depths of seismic discontinuities in the upper mantle using the observed receiver function, this paper developed an inversion method of peeling genetic algorithm. The whole studied depth is divided into several sections from surface, and then inversion is made for each section. The effects of multiple reflected and reflect-transformed phases at the shallower discontinuities on the refract-transformed phase at the deeper one are peeled. Floating point coding, arithmetical crossover, and non-uniform mutation were used in the genetic algorithm in the inversion of each section. The method was checked using the model ispai'91 and applied to the inversion of velocity structure beneath HIA station.
