针对核电工程选址中的能动断层地质调查工作需要,提出了利用共偏移距浅层地震反射时间剖面来拓展地质剖面解释深度的技术方法,通过物性和岩性的综合解释来提高对能动断层鉴别及其产状确定的可靠性.探测试验结果表明该方法是有效可行的.地质剖面上描述的断裂破碎带在共偏移距时间剖面上反应明显,二者可以相互印证,优势互补.该技术方法可用于类似工程地质调查和第四系覆盖较薄地区的隐伏断层探测.
Aiming at the need of active fault geological survey in site selection of nuclear power project, a technical method is proposed to extend the interpretation depth of geological sections by using shallow seismic reflection time profiles of common offset. Through the comprehensive interpretation of physical properties and lithology, Identification and confirmation of its occurrence.The detection results show that this method is effective and feasible.The fracture and fracture zone described on the geological profile has obvious reaction on the time-offset section of total offset, and the two can confirm each other and complement each other. Technical methods can be used for similar geological surveys and Quaternary fault coverage of thin areas hidden detection.
