Abstract

The invention provides a rapid tunnel surrounding rock quartz content obtaining method and application. Mineral analysis is carried out on each collected sample to obtain the quartz content in each sample, and the point load intensity, rebound hardness and wear resistance indexes of each sample are measured; the quartz content serves as an evaluation result, the point load intensity, rebound hardness and wear resistance indexes of the sample serve as evaluation indexes, and the degree that each calculation index relies on the evaluation result is calculated to determine the index weight of theevaluation index; and an integrated evaluation model is established, trained and verified, verification is not ended unless the model satisfies the set requirements, and the model after verificationis used to calculate the content of quartz in the surrounding rocks. The method has the advantage of rapid detection.

Description

technical field [0001] The present disclosure relates to a method and application for quickly obtaining the quartz content of surrounding rock in a tunnel. 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 full-face tunnel boring machine, can realize parallel and continuous operation of construction procedures such as excavation, support, and slag discharge. Generally, it is called hard rock TBM applied to rock formations, and the rock strength, hardness and wear resistance directly affect TBM tool life and TBM tunneling efficiency. The quartz content in the rock affects the degree of cutterhead wear and is an important parameter in TBM construction. It is of great significance to predict and evaluate the wear degree of the cutterhead through the quartz content to ensure the tool life and construction efficiency of TBM....
