Supporting data for "3D FWI for subsoil density: test on synthetic data for different force directions of the seismic source"-Chapter 4 and GJI paper

This dataset contains the supporting materials for Chapter 4 of Yusuke Kawasaki’s PhD project and the corresponding journal article published in <em>GJI</em>, which present a synthetic investigation of 3D FWI for estimating subsoil density. It includes synthetic seismic data, input files for the FWI workflow, investigation results, and the associated codes for FWI and result visualization. This dataset supports research aimed at demonstrating the advantages of using a horizontal-force seismic source for achieving more reliable density estimation in 3D FWI, compared with the use of a conventional vertical-force source.

本数据集包含川崎裕介（Yusuke Kawasaki）博士研究项目第四章，以及发表于《GJI》的对应期刊论文的配套支撑材料，相关工作围绕用于估算地下土层密度的三维全波形反演（Full Waveform Inversion，简称FWI）展开合成研究。该数据集涵盖合成地震数据、全波形反演工作流程所需的输入文件、研究结果，以及用于全波形反演与结果可视化的配套代码。本数据集可用于支撑相关研究，该研究旨在论证相较于传统垂直力地震震源，采用水平力地震震源能够在三维全波形反演中实现更可靠的地下土层密度估算。
