TUNNEL CONSTRUCTION LARGE-SCALE COMPREHENSIVE GEOPHYSICS ADVANCE DETECTION MODEL TEST APPARATUS

摘要

A tunnel construction large-scale comprehensive geophysics advance detection model test apparatus comprises a tunnel surrounding rock (1), a main tunnel model (2), a model test housing (3), a water-bearing geological structure apparatus (4), a numerical control automatic construction apparatus (5), and a main control chamber (6). The model test apparatus is a large-scale comprehensive geophysics advance detection model test apparatus that meets detection using a seismic wave method, an electromagnetic method, and a direct current method. The geophysics advance detection model test apparatus can be used for researching a geophysics response characteristic of the water-bearing geological structure apparatus existing in front of a tunnel heading face, verifying multiple forward and inversion methods of geophysics advance detection of the water-bearing geological structure apparatus, and researching a relationship between results of some geophysics detection methods and a water inrush amount, establishing a test basis for an advance forecast of the water-bearing geological structure apparatus and water inrush amount prediction in a practical project. Also disclosed is a tunnel construction large-scale comprehensive geophysics advance detection method.
