本项成果包括：提出天然地震走时反演层析成像技术，采用下列方法使得处理结果得以改善：１）利用３２个地震，４０４条射线的Ｐｇ，Ｓｇ，Ｐｍ，Ｓｍ，Ｐｎ，Ｓｎ等震相增加约束条件；２）用已有精度较高的人工地震测深结果作速度约束；３）用波形反演来修改模型，把波源，介质吸收，散射等物理特征集中反映在记录中，把诸多物理量开发出来互为约束，以修改后的模型再作反演，使解的稳定性大大提高；４）采用最优化过程，选择遗传算法，可以进行震源定位，走时反演，波形反演； ５）得到任意深度的速度分布及从地表到Ｍｏｈｏ面的速度剖面。主要应用结果：对于朝鲜半岛南部，划分为５（沿纬度）＊６（沿经度）＊８（沿深度）块，对于中部分２８８块．得到从地表到Ｍｏｈｏ面的８个水平切面；中部地区沿纬度１３个二维剖面及其Ｍｏｈｏ面深度分布。结果表明，这些剖面对认识大地构造、地质结构的稳定性，深部事件的性质是很有益的，对地球动力学研究也有重要意义。
The achievements of this project include: Propose natural seismic traveltime tomography, and improve the processing results by the following methods: 1) Using 32 earthquakes and 404 rays of Pg, Sg, Pm, Sm, Pn and Sn phases Increase the constraint condition; 2) use the artificial seismic sounding result which has high precision as the velocity constraint; 3) modify the model by the waveform inversion and reflect the physical characteristics such as wave source, medium absorption and scattering concentration in the record, The physical quantities are developed to be mutually constrained, and the modified model is then inverted to greatly improve the stability of the solution. 4) The optimization process is used to select the source localization, travel time inversion and waveform inversion; 5 ) To obtain any depth velocity distribution and velocity profile from the surface to the Moho surface. Main application results: For the southern part of the Korean Peninsula, divide into 5 (along the latitude) * 6 (along the longitude) * 8 (along the depth) blocks and 288 for the middle part. Obtained eight horizontal sections from the surface to the Moho surface; 13 two-dimensional sections along the latitude along the depth of the Moho surface in the central area. The results show that these profiles are very useful for understanding the tectonics, the stability of geological structures and the nature of deep events, and are of great significance for the study of geodynamics.
