Abstract

The invention provides a TBM tunneling tunnel rock quartz content rapid test system and method. According to the actually measured quartz content and hardness and wear resistance parameters of tunnelrock, through multivariate linear regression analysis or rough set-ideal point nonlinear analysis method, a multivariate linear empirical formula or a comprehensive evaluation model based on the parameters is established, an empirical estimation formula or a comprehensive evaluation model is established, and the method can be used for rapidly obtaining the quartz content of the TBM construction tunnel rock. The method is simple in principle, economical and practical, effectively replaces an expensive and time-consuming conventional rock quartz content testing method (a mineral analysis method), and solves the problems that a TBM tunneling tunnel rock quartz content instrument is high in price and complex in testing process. According to the method, the TBM cutterhead wear information can be quickly predicted, the state of the cutter can be reasonably evaluated, and great guiding significance is achieved for TBM tunnel construction.

Description

Technical field [0001] The present disclosure relates to a system and method for rapidly testing rock quartz content in TBM tunnels. Background technique [0002] At present, my country is building a large number of underground projects such as urban subway tunnels, water diversion tunnels, river-crossing-sea tunnels, and electric power telecommunication underground pipe corridors. The TBM construction method has the advantages of fast excavation speed, environmental protection, and high comprehensive benefits. It is the most promising mechanical equipment for rock tunnel excavation. It can realize the construction of deep-buried long tunnels with complex geographies that are difficult to achieve by traditional drilling and blasting methods. , Water conservancy, hydropower, municipal and other tunnel projects are growing rapidly. TBM, also known as tunnel hard rock boring machine, is mainly suitable for hard rock formations. For tunneling in hard rock formations, the quartz con...
