Machine learning-based tunnel rock quartz content test system and method

Abstract

The invention provides a machine learning-based tunnel rock quartz content test system and method. The system comprises an information acquisition system and a learning system, wherein the informationacquisition system is borne on a mechanical arm, approaches to surrounding rocks along with the movement of the mechanical arm and is used for learning indoor rock sample images and rock sample images practically observed via well logging according to received acquired data, recognizing texture features of different rocks through a local binary pattern feature extraction algorithm so as to different differences of different rocks in the aspects of color, structure and construction, integrating feature amounts through a support vector machine algorithm, and establishing a response informationquartz content prediction model so as to calculate contents of quartz in front rocks in TBM tunneling projects.

Description

Technical field [0001] The present disclosure relates to a system and method for testing the quartz content of tunnel rock based on machine learning. Background technique [0002] The statements in this section merely provide background information related to the present disclosure, and do not necessarily constitute prior art. [0003] TBM, also known as Tunnel Boring Machine (Tunnel Boring Machine), has been widely used in tunnel construction. It has the advantages of reduced labor intensity, convenient construction organization, fast construction speed, low environmental disturbance, and high safety. In the TBM tunneling process, the quartz content of the front rock mass affects the degree of wear of the cutter head, so it is decisive for the rock tunneling machine to adjust the tunneling parameters and ensure smooth tunneling. At present, the determination of quartz content in rocks mainly includes chemical methods and phase analysis methods. Chemical methods mainly include vol...

AI Technical Summary

Problems solved by technology

Although the above quartz content test method is relatively mature, it requires laboratory conditions, and the process of preparing samples and preparing related solutions is complicated, so the cost is also high. Obviously, the laboratory conditions are not available for TBM excavation; at the same time, the above methods are time-consuming and cannot be used. Meet the requirements of continuous rapid testing during TBM excavation
