综合地球物理方法在冻土调查中的应用与研究

THE APPLICATION AND RESEARCH OF COMPREHENSIVE GEOPHYSICAL METHODS IN PERMAFROST SURVEY

了解冻土在三维空间的分布情况、特征、类型,在高纬度地区开展重大基础建设工程的前提。针对特定的冻土调查对象和调查任务,为达到最佳调查效果,采用地球物理方法的组合(综合地球物理方法)。研究建立可以应用于多种、复杂地质环境冻土调查任务的方法技术体系。综合地球物理方法可以有效地降低单一地球物理调查方法在解释方面存在的多解性问题,提高地球物理勘探解释的可靠性。为冻土地基调查提供参考。

Understanding the distribution,characteristics,and types of permafrost in three-dimensional space is a precondition for carrying out major infrastructure projects in high latitude areas.Based on the investigation of permafrost in high latitudes,this paper emphasizes the investigation of permafrost using a variety of geophysical methods.A combination of geophysical methods(Integrated Geophysical Methods)was proposed to achieve the best survey results,which can effectively reduce the multi-solution problems existing in the interpretation of single geophysical survey methods and improve the reliability of geophysical exploration interpretation.For the task of investigation of combustible ice in permafrost regions,this project will establish a method system that can be applied to a variety of complex geological environment of frozen soil investigation tasks.
