AI Technical Summary

Problems solved by technology

For indoor model test research, there is still a lack of a systematic face simulation system, because the simulated face is usually carried out in a simulated tunnel, and the simulated tunnel is usually relatively narrow, which is inconvenient to replace the face, especially for Simulation of structural plane information, which can reversely reflect the structural stability of the tunnel face and tunnel, especially the research on the combination of various structural planes, which is very important for the early warning of the collapse control and early warning of fractured rock mass tunnels

Abstract

The invention discloses a tunnel face prefabricated circulation replacement simulation system and method. The system comprises a support. One side of the support is provided with a vertical elevating mechanism which is provided with a supporting frame used for fixing a tunnel face prefabricated mould. The top part of the support is provided with a horizontal moving mechanism which can be connected with the supporting frame to drive the supporting frame to move in the horizontal plane. The beneficial effects of the tunnel face prefabricated circulation replacement simulation system and method are that the large-scale and high-weight tunnel face mould can be transported by using the vertical elevating mechanism and the horizontal moving mechanism so that simulation of the large-scale tunnel face can be realized; the tunnel face prefabricated mould is adsorbed by using an electromagnetic chuck so that damage to the tunnel face structure caused by direct contact with the tunnel face can be avoided and disturbance of the experiment can be reduced; and the system is simple in structure and easy and convenient to operate so that the working efficiency can be enhanced.

Description

technical field [0001] The invention relates to a tunnel simulation test, in particular to a tunnel face prefabrication cycle replacement simulation system and method. Background technique [0002] Tunnel construction in my country is booming, and landslide accidents occur frequently. Most of the landslides in fractured rock tunnels are block collapses, and the occurrence process is mostly the chain effect caused by the falling of a certain block or some key blocks. Physical model test is one of the three main means of natural science research (theoretical research, experimental research and computer simulation calculation). For major geotechnical engineering structures, it can simulate complex geological structures more comprehensively and truly, and discover some New mechanical phenomena and laws provide the basis for establishing new theories and mathematical models. For indoor model test research, there is still a lack of a systematic face simulation system, because the...
