Embodiment Construction

[0048] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0049] At present, pre-earthquake expansion is based on the constitutive relationship of bulk rock materials, and a large number of rock experiments and seismic studies can provide support for the expansion model. The study found that once the expansion process is confirmed by observations, many other types of precursor phenomena can also be explained by this expansion model, but the...

Abstract

The invention provides a method and a system for calculating a loading and unloading response ratio and relates to the technical field of earthquake prediction. The method comprises the steps of acquiring a water level data time series, wherein the water level data time series includes water level data collected according to multiple preset time points; performing preprocessing and filtering operations on the water level data to obtain water level processing data; judging a loading and unloading state of each preset time point through a coulomb stress criterion, a tidal effective shear stressand a structural effective shear stress; and calculating the loading and unloading response ratio of each preset time point according to the loading and unloading state and the water level processingdata. The loading and unloading response ratio is calculated in a simple manner, and the reliability of the calculation result is improved.

Description

technical field [0001] The invention relates to the technical field of earthquake prediction, in particular to a method and system for calculating the response ratio of loading and unloading. Background technique [0002] In recent years, researchers have discovered that, in addition to earthquake catalogs, abnormal changes before strong earthquakes can also be found by using observation data such as groundwater level and crustal deformation, and they speculate that they may be related to the occurrence of subsequent strong earthquakes. However, these studies usually use tidal factors as the basis for judging loading and unloading, so it is difficult to achieve regularity. In fact, the effective shear stress and its changes play a decisive role in the process from microfracture generation, rock physical and mechanical properties change to earthquake occurrence. [0003] How to properly establish a model to accurately identify the generation and expansion of microcracks and ...
