摘　　要：利用哈密地区的巴里坤地震台和雅满苏地震台,以及周边的木垒地震台获取自2012~2016年接收到的远震波形数据,利用H-κ叠加法获取这些台站所在区域的地壳厚度和平均泊松比。结果显示该区域地壳厚度介于46.8~51.5 km,泊松比为0.253~0.276。这对该区的地质构造特征和孕震的研究分析具有积极意义。Using the teleseismic waveform data from 2012 to 2016 received by Balikun seismic station and Yamansu seismic station in Hami area and the surrounding Mulei seismic station, the crustal thickness and average Poisson’s ratio of these stations are obtained by using H-κ superposition method. The results show that the crustal thickness is 46.8~51.5 km, and Poisson’s ratio is 0.253~0.276. This is of positive significance to the study and analysis of the geological structure characteristics and seismogenic in this area.
