The embodiment of the invention provides a stress deformation detection system in an ice body and a glacier mobility evaluation system. The stress deformation detection system is composed of a frame having a hexahedron structure, a pressure gauge unit, a deformation gauge unit, and a computing device. The pressure gauge unit arranged at the surface of the frame is used for obtaining a main stress parameter at any point inside an ice body; the deformation gauge unit arranged at the rest of surface of the frame is used for obtaining a main stress deformation parameter at any point inside an ice body; and the computing device connected with the pressure gauge unit and the deformation gauge unit respectively and electrically is used for estimating the motion of a glacier where the frame is located based on the main stress parameter and the main stress deformation parameter. Therefore, the main stress parameter and the main stress deformation parameter inside the ice body are obtained and thus the internal stress state of the ice body is deduced and analyzed based on the obtained parameter information, so that the glacier motion trend and the internal pressure evolution process are obtained.
Description
technical field [0001] The invention relates to the technical field of detection and measurement, in particular to a stress and deformation detection system in ice and a glacier movement evaluation system. 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] Because 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 rod (flower rod), and some detection systems have complex structure...
