Abstract

The invention discloses a rockburst prediction method for a TBM tunneling tunnel. The rockburst prediction method comprises the steps of establishing a related multi-dimensional normal cloud model, carrying out test simulation, establishing a test model, carrying out AI data analysis and carrying out dynamic data acquisition. According to the method, a multi-dimensional normal cloud model is established according to tunnel engineering characteristics and rock burst inducing factors, so that effective parameter information can be conveniently and quickly screened; by researching surrounding rock failure characteristics and influence factors of different types of rockburst, a powerful test means is provided for selecting a reasonable construction method and a support system in a constructionstage; a risk grade evaluation model is established, so that rock sample parameters and corresponding collected data are directly input in the actual tunnel construction process, a risk grade evaluation result is obtained, rockburst information of a corresponding rock sample can be comprehensively obtained, and countermeasures are taken in advance once; micro-seismic sensors are distributed on aplurality of monitoring sections in an X shape, a vibration signal monitoring network is established, and vibration information in each radial direction and each axial direction in the sections can becomprehensively acquired.

Description

technical field [0001] The invention relates to the field of tunnel engineering, in particular to a rockburst prediction method for TBM tunneling. Background technique [0002] The broad meaning of TBM refers to the tunnel boring machine. It is divided into open tunnel boring machine and shield tunnel boring machine. The construction procedures such as excavation, support, and slag discharge are operated in parallel and continuously. It is a factory-like assembly line tunnel construction equipment integrated with mechanical, electrical, hydraulic, optical, and gas systems. It has the advantages of fast excavation speed, environmental protection, and high comprehensive benefits. It can realize The construction of deep and long tunnels with complex geographical landforms, which is difficult to realize by traditional drilling and blasting methods, is rapidly growing in China's railway, hydropower, transportation, mining, municipal and other tunnel projects. The narrow meaning...
