| 英文简介 | Studying of the ground ice spatial distribution characteristics and ice content is of great significance to the engineering construction and environmental research in permafrost regions. Among the methods of ground ice monitoring, electrical resistivity tomography has advantages such as non-destructive, efficient and consecutive monitoring in two-dimensional or three-dimensional ways, but some problems existed, such as absence of relational models between permafrost electrical resistivity and ice content, deficiency in application research and difficulty in quantitative interpretation. By testing electrical resistivity of undisturbed permafrost samples, forward and inversion modeling of electrical resistivity tomography, laboratory model experiments, we establish relations between permafrost electrical resistivity and ice content, optimize arrays of data collecting, select inversion algorithm based ground ice patterns, and assess the accuracy of the inversion results. At last, we will reveal the ground ice characteristics of spatial heterogeneity and calculate ground ice reserves in local area on the Qinghai-Tibet Plateau. The research results will lay a foundation for studying the interactions between ground ice and engineering constructions and ecological environment. |
