Benefits of technology

This patented technology helps researchers identify areas where there are positive underground water bodies that may have caused damage or pollution during times they were drilling into them. It also provides data on these damaged regions' appearance over time through analyzing its structure and sediments content. These technical results help explorators better advise future actions related to environmental concerns such as prevention measures like rebuilding roads after construction activities.

Problems solved by technology

This patented technical problem addressed by this patents relates to studying stress corrosion crack initiation caused by lateral pressure during earthquake activity that can lead to damage from tensile failure under repeated loading conditions over time. Existing techniques such as multiple stage simulations may be limited because they only work with one type of material at once (single) rather than two types simultanously like multistage expansions).

Abstract

A negative inversion structure cause analysis method and system, an electronic device, and a storage medium, the method comprising: constructing a geological generation model of a negative inversion structure, the geological generation model comprising two stratums separated by a pre-stored slab fault; the geological generation model is correspondingly controlled sequentially according to an extrusion stage and an extension inversion stage, and the extension angles of the two stratums in the extension inversion stage can be adjusted; recording geometric and kinematic characteristics of the geological generation model at different extension angles in each stage; and acquiring geographic features of a to-be-analyzed region, matching the geographic features with the geometric and kinematic features, judging whether the to-be-analyzed region belongs to a negative inversion structure, and if so, acquiring an extension angle of the to-be-analyzed region in an extension inversion stage. By means of the method, cause analysis can be conducted on the negative reversal basin in the river-side depression, the tectonic deposition appearances of the negative reversal basin in different periods are analyzed, and supplementary suggestions are provided for geological exploration of the basin.
