The embodiment of the invention provides a method and a system for detecting stress deformation in an ice body. The method is applied to the system for detecting stress and deformation in the ice body. The system comprises a computing device and an acquisition device, wherein the acquisition device comprises a pressure gauge unit and a deformation meter unit. Main stress parameters of any point inside the ice body can be acquired through the pressure gauge unit, and the acquired main stress parameters are transmitted to the computing device. Main strain parameters of any point inside the ice body can be acquired through the deformation meter unit, and the acquired main strain parameters are transmitted to the computing device. The computing device analyzes the force bearing condition of the ice body according to the main stress parameters and the main strain parameters. The main stress parameters and the main strain parameters of any point inside the ice body can be acquired, analysis is carried out according to the acquired data, and the movement of a glacier can be estimated.
Description
technical field [0001] The invention relates to the technical field of detection and measurement, in particular to a method and system for detecting stress and deformation in ice. Background technique [0002] Detecting the movement of glaciers is of great significance to the study of glaciers. As a special material, ice is very important to obtain and accurately describe the stress state and strain state at any point inside it during the geometric and mechanical analysis of glacier movement. In the process of monitoring and recreating the movement of glaciers, the distribution and variation of the deformation field of the ice body is an important analysis object and control index. [0003] Since it is difficult to set a relatively constant reference point position on the glacier body, it is difficult to determine the three-dimensional position change of the traditional measuring pole (flower pole). Therefore, it is an urgent problem for those skilled in the art to provide...
