A real-time sensing system and method for TBM digging rock mass state

Abstract

Provided are a TBM boring rock state real-time sensing system and method, used to solve the problem that existing means cannot effectively reflect a TBM tunnel boring rock state in real time so as to facilitate the selection of a suitable boring plan. Hard rock tunnel TBM boring parameters and corresponding rock state parameter data are collected, a data storage repository module is established, a rock-machine relationship sensing model and a clustering algorithm are established via step-by-step regression to implement rock mass grading, a calculation module kernel is formed, rock state information is calculated in an inverse manner within a model calculation module by reading current TBM boring parameters during boring, and the rock state information is presented in real time on a TBM host computer visual interface via a real-time output display module. The present invention overcomes defects such as rock condition parameters being difficult to obtain, traditional means lagging behind, and rock states in front of tunnel faces being unknown. The present invention reduces TBM energy consumption, ensures equipment and personnel safety, increases TBM boring efficiency, and significantly improves TBM safe and efficient boring capabilities.

Description

technical field [0001] The invention relates to the technical field of TBM tunnel construction, in particular to a system and method for real-time sensing of the state of a TBM excavating a rock body. Background technique [0002] TBM is a major technical equipment for tunnel construction that integrates machinery, electricity, and hydraulic pressure. It can realize tunneling, rock slag shipment, and tunnel wall support in one excavation. It has high mechanization and automation, fast tunneling speed, and safe construction. Civilized and environmentally friendly and other significant advantages, it has been widely used in underground construction such as hydropower, railways, coal mines, and urban subways in many countries around the world. [0003] Due to the limitation of time, cost, technical level and many other factors, the geological survey before TBM tunnel construction cannot be very detailed and accurate, and unfavorable geological conditions that are not indicated ...
