摘　　要：通过分析传统纸质线划点之记、场地图、地质断裂活动构造图及台站观测环境等地震资料存在查阅繁琐、表达形式单一和信息量匮乏的诸多弊端,给出了“全国地震数据空间应用管理平台”的整体设计思路与功能模块实现过程,同时基于倾斜摄影测量与结构运动恢复技术(SfM),以典型跨断层场地为例,对现有二维平面地震数据构建了厘米级高分辨率三维实景模型,并将其植入该管理平台。使用效果表明:地震资料实景三维表达不但还原了外业实地监测场景和断裂产状等信息,还可提取观测曲线、活动构造定量参数,给相关科研工作者带来了全新的使用体验,更为我们传统会商提供了一种新型的会商模式。By analyzing the disadvantages of traditional seismic data(site maps,the tectonic maps of geological fault activity,and the observation environment data of stations),i.e.,cumbersome access,a single expression form,and a lack of information,this paper presents the overall design idea and function module implementation process of the“national seismic data spatial application management platform.”Meanwhile,taking a typical crossfault site as an example,a centimeter-level high-resolution 3D scene model was constructed for the existing two-dimensional plane seismic data based on tilt photogrammetry and structure from motion technology,and it was then implanted into the management platform.The results show that the 3D expression of seismic data can not only restore the field monitoring scene and fault occurrence but also extract the observation curve and quantitative parameters of active structures,thus bringing a new application experience to relevant scientific researchers and providing a new consultation mode for our traditional consultation.
