摘要
现代物探技术在冻土勘查和研究中始终发挥着重要的作用 .40a来通过不断努力 ,我国冻土物探事业的发展历经了从无到有、从手段简单到方式多样、单一物探参数到多参数反映冻土诸多特征的发展历程 .通过物探手段在不断提高冻土类型识别和划分精度等方面均取得了长足的进步 ,现已成为我国多年冻土勘察、动态监测、变化规律认识和环境工程地质评价等研究中的关键手段之一 .文章分别就地球物理勘测方法在我国寒区中的应用、研究、现状 ,国际开展相关的研究内容和我国在相关研究领域中的地位。
Modern geophysical methods and techniques play an important role in investigating and studying permafrost. In China the application of geophysical methods to permafrost began from the early 1960 s. Since, it develops from single and simple methods to integrated methods to investigate different kinds of frozen soils, from getting single geophysical parameter to multi-parameters to reflect the general characteristics of frozen soils. Through more than 40 years hard working, great progress has been made in study and application of geophysical techniques in permafrost regions, especially in continuously improving the ability and precision in distinguishing frozen soils, and get some important information and parameters about frozen soils. The application of modern geophysical methods has become one of the key methods in investigating the state and three-dimensional properties of permafrost and monitoring the permafrost change and development. In this paper the foundations, based on which geophysical methods can be used in permafrost exploration, the development of geophysical technique in recent years; the great improvement of ability of resolving practical problems, the precision in distinguishing frozen soils; and the advantage and disadvantage of these methods are described. And farther more, this paper points out the large gap between China and the other countries and the scientific application abroad. What problems exist, what should be paid attention to and what should do in China in the future are also put forward.
