Physical simulation experiment method and device for monitoring shearing force of earthquake triggering cross section surface

Abstract

The invention discloses a physical simulation experiment method and a device for monitoring shearing force of an earthquake triggering cross section surface, wherein, a stress sensor is utilized for making a related earthquake zone cross section model as per a certain proportion according to actual topography, so as to carry out internal stress change monitoring; and an earthquake zone cross section mechanical model and a mathematical formula are further combined for calculating the shearing force in the earthquake triggering cross section surface at different stages, thereby drawing a curve of the relation between the shearing force and time and displaying the value of internal stress at any time. The change process of the shearing force of the unpredictable cross section surface is detected by utilizing measurable disturbing force and the corresponding function relation, thereby really realizing advanced and real-time early-warning and forecasting of earthquake disasters. The whole structure is designed reasonably, the use is convenient and the simulation effect is realistic.

Description

technical field [0001] The invention relates to the field of geotechnical engineering earthquake disaster prediction and prediction, in particular to a physical simulation experiment method and an experiment device for monitoring the shear force of an earthquake-generating fault plane. Background technique [0002] Earthquake is a natural phenomenon that can bring huge disasters to human society. Its most prominent feature is its suddenness and shockingly huge destructive power. If the time, location and intensity of future major earthquakes can be accurately predicted, it will undoubtedly greatly reduce the disasters caused by earthquakes to humans and save the lives of countless people living in earthquake-risk areas. Since the 1960s, earthquake prediction, especially mid- and long-term prediction, has made some meaningful progress. In terms of long-term prediction, the most prominent progress is the confirmation of the large earthquake gap at the plate boundary. However,...
