Abstract

The invention discloses a forecasting method and a forecasting system for tunnel geology. The method comprises the following steps: surveying the geology of a tunnel with a seismic reflection method according to the geological condition of the peripheral area of the tunnel; determining a suspicious geological segment according to the surveying result of the seismic reflection method; surveying the determined suspicious geological segment with an advanced drilling method to obtain the geological analysis data of suspicious geological segment; and forecasting the geology according to the geological analysis data of the suspicious geological segment. According to the method and the system, the problem of potential safety hazard existing in tunnel construction since the geological condition of the tunnel cannot be forecasted accurately with a single tunnel geological surveying method is solved, and the practicability of forecasting is improved.

Description

technical field [0001] The invention relates to the field of tunnel construction, in particular to a method and system for predicting tunnel geology. Background technique [0002] In the tunnel construction method, advanced geological prediction is based on the tunnel design, in order to ensure the safety of tunnel construction, guide the construction of tunnel engineering, and improve the quality of tunnel engineering construction. At the same time, according to different geographical environments, the methods of advanced geological prediction used in tunnel construction are also different. For example, in areas where there are underground rivers, when it is necessary to pass through the underground river for tunnel construction, advanced geological forecasting must be carried out to detect possible water inrush in front of the tunnel face, so as to guide the correct decision-making of tunnel construction and avoid construction occurrence of geological disasters.
