Abstract

The invention provides a real-time sensing system and method of the tunneling rack mass state of a TBM. The method and system is used for solving the problem that an adaptive tunneling scheme cannot be selected due to the fact that the tunneling tunnel rack mass state of the TBM cannot be effectively reflected in real time through existing means. By collecting hard-rock tunnel TBM tunneling parameters and corresponding rock mass state parameter data, a data storehouse module is built; step-by-step regression is adopted, a rock-machine relationship sensing model is built, and a clustering algorithm is adopted to achieve rock mass quality grading and form a calculation module kernel; in a model calculation module, by reading current tunneling parameters of the TBM in a tunneling project, back calculation is conducted to obtain rock mass state information, and the rock mass state information is displayed on a TBM upper computer visible interface in a real-time output and display module inreal time. By means of the system and method, the deficiencies of difficult obtaining of traditional rock mass condition parameters, backward means and unknown rock mass state in front of the tunnelface are made up for; energy consumption of the TBM is reduced, the equipment and personnel safety is guaranteed, the tunneling efficiency of the TBM is improved, and the safe efficient tunneling capability of the TBM is greatly improved.

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 ...
