地震勘探技术在公路采空区调查中的应用
|
摘要
采空区是高速公路、铁路、大堤等基础设施建设的重大地质隐患,必须及时地查明并进行综合治理。由于采空区自身形成的一些特点,与围岩之间一般存在较明显的密度、速度等物性差异,因此用地震勘探技术对采空区进行探测是地质灾害调查的重要手段。本文结合某公路采空区地质勘查实例,详细地阐述了地震勘探技术原理、野外实测技术以及数据处理和资料解释全过程。结果表明该方法在公路地质灾害调查方面具有探测深度大、分辨率高、精确有效等优势,能够弥补其他方法的不足。
Goaf is the grave geologic hidden trouble in the infrastructure construction such as superhighway,railway and dam,we must detect it's domain and have integrated control in time.Because the goaf has its own feature when it is formed,it is quite different from its surrounding rock on physical property such as density,velocity property.So the seismic prospecting technology method is the important means of goaf geologic survey.This paper briefly introduced the working principles,field observing techniques,data processing and analysis about seismic prospecting technique with some practical examples of goaf under highway.Results show that this method has lots of advantage in geological disaster investigation,for example,great detecting depth,high resolution,effective and so on.It is able to make up for advantages of other methods.
