近年来,随着多年冻土地区的开发和建设,迫切需要提供有效的冻土调查方法,剌激了冻土地球物理方法的迅速发展,新技术新方法的试用也有很大进展。地震法和直流电法的应用范围逐渐扩大,解决的问题越趋深入。各种交流电磁法、地质雷达、激发极化法以及遥感技术已进行野外试验,有的开始推广应用。冻土的电学性质、声学性质和弹性性质的研究已深入到研究冻土的物理力学性质、微观结构和物理化学过程。本文主要概述近年来多年冻土地球物理方法的研究状况。
In recent years, with the development and construction of permafrost regions, there is an urgent need to provide effective methods for permafrost investigation, stimulate the rapid development of geophysical methods in permafrost regions, and make great strides in the trial of new technologies and new methods. The scope of application of the seismic method and the direct current method is gradually expanding, and the problems to be solved are further deepened. Various AC electromagnetic methods, geological radar, induced polarization and remote sensing technology have been field experiments, and some began to promote the application. The study of the electrical, acoustic and elastic properties of permafrost has gone deep into the study of the physical and mechanical properties, microstructure and physicochemical processes of frozen soils. This article mainly summarizes the research status of permafrost geophysical methods in recent years.
