Problems solved by technology

However, the inventor found that most of the front-line construction workers in the tunnel lack good geological knowledge, and cannot timely and effectively identify the precursory features of the alteration zone to adjust the construction plan, which eventually leads to some disasters

Abstract

The invention provides a TBM-mounted rock alteration characteristic recognition and geological prediction system and method. The system comprises a detection device, and the detection device is carried on the side face of an open type TBM supporting shoe through a telescopic mechanism; the detection device comprises a dryer and an alteration characteristic detection device, and the dryer is used for drying target surrounding rock, so that rock information collected by the alteration characteristic detection device is not interfered by moisture; the alteration characteristic detection equipmentis configured to collect images, mineral types and contents and element types and contents of the target surrounding rock; an alteration characteristic database in which the mark images, the characteristic minerals and the sensitive elements have a quantitative representation relationship with surrounding rock alteration characteristics is pre-stored in the data analysis platform; and the data analysis platform is configured to extract mark images, characteristic minerals and sensitive elements related to alteration characteristic changes, compare the mark images, the characteristic mineralsand the sensitive elements with the alteration characteristic database, predict alteration characteristics of surrounding rock in front of the tunnel face, and finally realize a geological predictionfunction of an alteration zone.

Description

technical field [0001] The disclosure belongs to the field of feature identification of unfavorable geological precursors and advanced geological prediction of tunnels, and in particular relates to a TBM-mounted rock alteration feature identification and geological forecast system and method thereof. 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] Igneous rocks such as granite and tuff are hard, complete and stable engineering rock masses, and are generally considered ideal places for building tunnels and underground projects. In addition, when building deep and long tunnels in igneous rocks such as granite and tuff, it is suitable to use TBM (Tunnel Full-face Rock Boring Machine) for excavation. It has obvious advantages such as high efficiency, but TBM has high requirements on geological conditions. When the geological conditions are p...
