AI Technical Summary

Technical Problem

Existing technologies are mostly two-dimensional simulation structures, which cannot effectively simulate areas with large surface undulations and sudden external disturbances in actual tunneling operations, resulting in low test and detection accuracy and failing to meet actual needs.

Method used

A three-dimensional loading similar material testing system is designed. By combining a servo actuator and a tilting platform, multi-angle loading and simulation of sudden external condition disturbances can be achieved. By utilizing the cooperation of the servo actuator and the tilting platform, tunneling operations and changes in external conditions can be simulated, thereby improving the test accuracy.

Benefits of technology

It achieves high-precision testing and detection, can simulate soil and rock disasters under complex geological conditions, improves the comprehensiveness and realism of the test, and meets the needs of actual engineering.

Abstract

The application is suitable for similar material simulation test, and provides a three-dimensional loading similar material test system for simulating underground rock and soil disasters, which comprises a base plate, a model box fixedly connected to the surface of the base plate, an end cover plate fixedly connected to one end surface of the model box, servo actuators arranged in a rectangular array on both sides of the model box and the top thereof and away from the end cover plate, a rectangular pressing plate arranged at the end of the servo actuator, a box seat arranged on the surface of the base plate and located at the bottom of the model box, transmission shafts arranged in a linear array between the two ends of the box seat, adjacent two transmission shafts connected to each other through transmission belts at one end and located at the end of the box seat, and a turnover platform arranged in a linear array between the two sides of the upper surface of the box seat. The device solves the problem that the current similar material test equipment has great limitations and lacks test simulation of working conditions under sudden external condition disturbance, guarantees the precision of test detection, and greatly improves the comprehensiveness of simulation test under the working condition of sudden external condition disturbance.
