摘要
沪杭磁悬浮交通线路工程场地地震安评近场工作属于线状并且是长线工程项目,该长线工程场地经过多条复杂活动断层。活动断层的探测是工程场地地震安全性评价近场工作中的重要工作。本文结合抗干扰高分辨率浅层地震技术在沪杭磁悬浮交通线路工程场地地震安评近场工作中的应用,通过对该长线工程沿线的城市干扰源及干扰源特征分析,总结一套应用于长线工程场地的野外数据采集及数据处理的方法。最后以沪杭磁悬浮沿线塘栖—越东断层探测为实例,进一步证实了抗干扰高分辨率浅层地震技术在长线状工程场地地震安评近场工作中的应用效果,从而为长线工程场地地震安坪、高速铁路等重大长线工程断裂活动性的探测提供方法和依据。
TThe near-field seismic safety evaluation work for the site of maglev traffic-line project between Shanghai and Hangzhou belongs to a long-line project. It passes through many complex active faults. To investigate these faults is the most important in near-field seismic safety evaluation. By means of the shallow seismic technology of anti-disturbance high resolution, this paper studies and analyzes the noise sources and their characteristics along cities by the line. Though this investigation, we conclude with a set of methods for filed data acquisition and processing. Finally, we give an example of investigating the Tan- gxi-Yuedong fault along Shanghai-Hangzhou maglev transrapid to further confirm the effectiveness of the shallow seismic technique of the anti-disturbance high resolution using seismic safety evaluation and then provide an effective method for long-line seismic safety evaluation or faults investigation of high-speed railway.
