Description

technical field [0001] The invention relates to a method for advanced geological prediction of underground engineering. Background technique [0002] Tunnel and tunnel engineering are special engineering-geological engineering, which is different from general civil construction engineering. It is a kind of special construction engineering that uses geological bodies as building materials, part or all of engineering structures, and takes the geological environment as the building environment. Its theoretical basis is geological cybernetics-geological structure cybernetics, rock (soil) structure cybernetics, karst cybernetics, and geological environment cybernetics. The basic method of geological engineering design and construction is geological monitoring construction method, and advanced geological forecasting is An important part of the geological monitoring construction method is an objective requirement for the dynamic design and construction of tunnels and tunnels.

Problems solved by technology

[0004] At present, there is no uniform standard for the division of advanced geological forecasting for underground engineering. Most of them are divided into two stages: long-term and short-term forecasting according to the detection distance of geophysical prospecting. There are few studies on the steps and methods, and few examples of practical application. In the comprehensive application of advanced geological prediction technology, it is common to make advanced geological predictions after advanced detection with only two or two advanced geophysical methods. It is also difficult to achieve ideal results by using advanced geophysical prospecting instruments. In the selection of geophysical prospecting methods, the combination cannot be optimized according to the actual geological conditions of the tunnel (tunnel), and the prediction cost is high and the prediction accuracy is low.
