Virtual earthquake disaster scene optimization method based on earthquake rescue virtual drilling system

Abstract

The invention discloses a virtual earthquake disaster scene optimization method based on an earthquake rescue virtual drilling system. The method comprises the following steps: 1, a primary model is established; 2, according to the primary model, a macroscopic disaster area model, a search area model and a work site model are established with three layers of different detail degrees, the models with the different detail degrees correspond to different drilling tasks, and the earthquake rescue virtual drilling system comprises an earthquake rescue drilling scene setting subsystem; an earthquake rescue drilling analogue simulation subsystem; and an earthquake rescue drilling performance evaluation subsystem; the step 1 comprises the steps of according to an earthquake occurrence principle, establishing an earthquake motion model and simulation; building a building damage model and simulation according to the intensity and a building anti-seismic structure principle; according to an emergency behavior principle, establishing a disaster victim behavior model and simulation; establishing a secondary disaster model and simulation according to the earthquake secondary disaster theory; and establishing a department collaborative rescue model and simulation according to the actual earthquake rescue emergency plan.

Description

technical field [0001] The invention belongs to the technical field of emergency training, in particular to a virtual earthquake disaster scene optimization method based on an earthquake rescue virtual drill system. Background technique [0002] The area where the earthquake caused disastrous consequences is also the area where the cultural landscape is most concentrated, which makes the well-ordered cultural landscape suddenly unrecognizable and becomes a chaotic scene. The damage scene is extremely complicated. The ground vibration caused by the earthquake will damage buildings and bridges, interrupt Electricity and telecommunications equipment, even causing landslides, floods, fires and huge tsunamis, the scene is complex and diverse, and the structure of the irregular entities stacked, covered, interspersed and implicated in the earthquake damage site is extremely complex, so the earthquake site It is not feasible to model each part in detail, so the optimization of the ...
