Ground-deformation Form and Control Factors Caused by Irrigation

Abstract

Since irrigation in1968, ground deformation and geological disasters frequently happened. Based on depth investigation, survey and experimental research, this paper comprehensively analyze the geological environment background of Heifangtai. The distribution and types of ground deformation were systematically categorized. On this basis, this paper analyze control factors of ground deformation. Topography, geological structure, stratigraphy and lithology are the internal factors, while irrigation is the main predisposing factor. The ground deformation is the result of various factors. Study will provide the foundation for geological environment caused by irrigation. This paper has some theoretical and practical significance.
