Abstract

The invention discloses an evaluation system and method for evaluating rock mass grades based on impact acceleration changes. The evaluation system comprises at least one acceleration signal sensitiveelement, an Internet of Things gateway and a server. The server is configured to receive acceleration signals of at least two vibration periods and acquire the impact section peak acceleration of each vibration period according to the acceleration signals, and the server acquires an acceleration difference value between the impact section peak accelerations of the two adjacent vibration periods.The server evaluates the rock mass grade of rock mass to be tested according to at least one acceleration difference value and a pre-configured evaluation model. The evaluation system provided by theembodiment of the invention can collect the impact section acceleration of a rock drill in each vibration period during multiple continuous drilling, and evaluate the rock mass grade of the rock massto be tested according to the difference of the impact section accelerations between the adjacent vibration periods.

Description

technical field [0001] The invention relates to the field of rock and soil mechanics, in particular to an evaluation system and method for evaluating rock mass grades based on impact acceleration changes. 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 identifying stratigraphic boundaries and classifying surrounding rocks. At present, the drilling rig response information in the field of geotechnical engineering has not been fully collected and applied. Contents of the invention [0003] Embodiments of the present invention at least disclose an evaluation system...
