Abstract

The invention discloses an evaluation system and method for evaluating rock mass grades based on acceleration signals. The evaluation system includes at least one acceleration signal sensitive element, an IoT gateway and a server; the acceleration signal sensitive element is configured to be installed in the drilling direction of the rock drill, and obtains the acceleration of the rock drill when drilling a rock mass to be tested, and the acceleration sensitive element is based on Acceleration generates an acceleration signal; the acceleration signal sensitive element sends the acceleration signal to the server through the Internet of Things gateway; the server is configured to receive the acceleration signal of at least one vibration cycle, and evaluate the to-be-tested acceleration signal according to the received acceleration signal and an evaluation model previously configured. The rock mass grade of the rock mass. The evaluation system of this embodiment can collect the vibration acceleration data generated by the rock drill at various stages during drilling, and evaluate the rock mass level that has potential correlation with the vibration acceleration according to the vibration acceleration data at each stage.

Description

technical field [0001] The invention relates to the field of geotechnical mechanics, in particular to an evaluation system and method for evaluating rock mass grades based on acceleration signals. Background technique [0002] During the drilling process, the drilling is in direct contact with the rock and soil mass. The response information of the drilling rig comprehensively reflects the mechanical properties of the rock and soil mass. A large amount of geological data hidden in the response information of the rock drilling rig can be used to analyze and measure the mechanical parameters of the rock and soil mass. It is an important reference index for stratigraphic interface identification and surrounding rock grade division. At present, the rig response information in the field of geotechnical engineering has not been fully collected and applied. SUMMARY OF THE INVENTION [0003] The embodiments of the present invention disclose at least one evaluation system for eval...
