摘要:
重大水利水电、交通及城市地下空间工程的建设，正面临日益复杂的水工环地质条件，精细勘查隐伏断裂、岩溶、破碎带等不良地质体，是保障工程安全的核心前提。常规钻探与二维物探手段在描述这些地质体的精细空间展布与连通性方面存在固有局限性。三维地震技术凭借其高分辨率、三维“体”成像及多属性分析优势，为水工环地质勘查提供了革命性工具，但其应用方法学尚待系统化。从岩石物理学入手，系统分析典型不良地质体及水文地质结构的地震响应机理与波组特征针，对水工环勘查的浅层、小尺度目标，提出了包含高分辨率处理、地震属性优选与“井—震”结合的三维地质解译流程。在此基础上构建地质灾害评估框架，旨在为三维地震技术在重大工程选址、设计与风险管控中的深化应用提供方法论支撑。
Abstract:
The construction of major water conservancy and hydropower, transportation, and urban underground space projects is facing increasingly complex hydrogeological and environmental geological conditions. Fine explora‐tion of unfavorable geological bodies such as hidden faults, karst formations, and fractured zones is the core prereq‐uisite for ensuring project safety. Conventional drilling and 2D geophysical methods inherently struggle to character‐ize the fine-scale spatial distribution and connectivity of these geological bodies. 3D seismic technology, with its ad‐vantages of high resolution, 3D volumetric imaging, and multi-attribute analysis, provides a revolutionary tool for hy‐drogeological and environmental geological surveys, yet its application methodology needs to be systematized. Start‐ing from rock physics, this paper systematically analyzed the seismic response mechanism and wave group character‐istics of typical unfavorable geological bodies and hydrogeological structures. Aiming at the shallow and small-scale targets of hydro-environmental geological exploration, a 3D geological interpretation workflow incorporating high-res‐olution processing, optimized seismic attribute selection and borehole-seismic joint interpretation was proposed. On this basis, a geological hazard assessment framework was established to provide methodological support for the in-depth application of 3D seismic technology in site selection, design and risk management of major engineering proj‐ects.
