【摘要】 利用安徽数字地震台网2009～2012年记录的421条高质量近震纵波数据,建立层状介质模型,基于遗传算法对安徽中部地区(30.5～33.2°N,116～119.3°E)地壳一维速度结构进行反演,结果显示遗传算法能够较好的用于一维速度结构反演,同时得到该地区地壳平均厚度、地壳各层平均厚度及各层中P波平均速度,为进一步开展该地区基础研究提供一个合适的初始地壳模型。更多还原

【Abstract】 Using 421 high-quality P-wave data of local earthquakes recorded by Anhui digital seismic network from 2009 to 2012,we create a layered medium model,inverting the average crust velocity model based on genetic algorithm in the central region of Anhui(31.15～31.6°N,116～116.45°E).The result shows that the genetic algorithm is adequate to inverse 1-D velocity structure of crust,the average thickness of the crust in this region,the average thickness and velocity of P-wave of each layer provide a suitable initial crust model for further basic research in this region.更多还原
