Solution Overview
Problem
Existing seismic fault simulation devices fail to accurately simulate wide fracture zones, as they typically result in narrower fracture widths compared to real-world seismic faults, and lack a unified scheme for experimental studies under strong seismic fault coupling.
Innovation Solution
A wide fracture zone fault simulation device with seismic simulation vibration table arrays, comprising a left box body, segmented box body structure, right box body, bottom spring structures, and vibration tables, allowing for dislocation in X, Y, and Z directions, with bottom plate structures and canvases to prevent soil-rock material loss during deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional vibration tables or driving devices are used to dislocate box bodies filled with soil-rock material, then seismic fault simulation is achieved, but the width of the simulated fracture zone is relatively narrow compared to real-world seismic faults
Solution Approach 1:
The box body is divided into multiple segmented box bodies (first segmented box body, second segmented box body, third segmented box body, fourth segmented box body) that can dislocate relative to each other. This segmentation allows the simulation of wide fracture zones by creating multiple discrete segments that can move independently, thereby expanding the simulated fracture zone width to match real-world seismic fault scales.
Solution Approach 2:
The invention introduces multi-directional dislocation capabilities (X-direction, Y-direction, and Z-direction) through parallelogram hinge structures and bottom spring structures. This dimensional expansion enables the simulation of complex wide fracture zone geometries that cannot be achieved with traditional single-direction vibration tables, accurately representing the three-dimensional nature of real seismic faults.
2Reliability
If box bodies are dislocated through vibration tables to simulate seismic faults, then fault simulation is achieved, but there is no unified and feasible scheme for experimental study of cross-fault structures under strong seismic fault coupling
Solution Approach 1:
The invention employs dynamic bottom spring structures and parallelogram hinge structures that enable flexible, multi-directional movement of segmented box bodies. These dynamic components allow the system to adapt to various seismic fault scenarios and coupling conditions, providing a unified yet flexible scheme for experimental studies without requiring multiple specialized devices.
Solution Approach 2:
The vibration table system is designed to perform multiple functions: it can dislocate box bodies in X, Y, and Z directions; simulate different seismic fault types; and study cross-fault structures under strong coupling conditions. This multi-functionality is achieved through the combination of segmented box bodies, bottom spring structures, and parallelogram hinge structures, creating a universal platform for comprehensive seismic fault research.
3Loss of substance
If segmented box bodies are connected through bottom plate structures and canvases, then soil-rock material loss is prevented during deformation, but the device structure becomes more complex
Solution Approach 1:
Canvases are used as flexible connecting elements between adjacent segmented box bodies. These thin film structures effectively prevent soil-rock material from falling or losing during box body dislocation and deformation, while adding minimal structural complexity compared to rigid alternative solutions.
