Description

technical field

[0001] The invention relates to a geological condition forecasting system and a forecasting method in front of a construction face. Background technique

[0002] During the excavation of underground projects, construction workers generally encounter the confusion of unknown geological conditions ahead. Although a certain degree of survey and design has been done in the early stage of construction, due to the limitations of various factors such as funds, site conditions, and technical means, it is difficult for the preliminary survey data to meet the technical requirements of underground engineering excavation. On the other hand, due to the limitation of the site conditions of underground engineering excavation, it is difficult to use the existing exploration technology to carry out advanced geological prediction for a certain distance ahead of the excavation. Currently, the tunnel earthquake prediction method is widely used in rock tunnel engineering. The ma...
