Construction method of advanced geological forecast

Abstract

The invention discloses a construction method of advanced geological forecast, which belongs to the technical field of geological forecast. The construction method comprises the steps of conducting tunnel engineering geological investigation; completing on-site data collection; establishing a wave velocity model; obtaining chromatography scanning image; conducting the analysis of tunnel engineering underground water advanced forecast, the analysis of tunnel engineering empty cavity advanced forecast, the analysis of tunnel engineering fault fracture zone advanced forecast, and the analysis of tunnel engineering surrounding rocks classification advanced forecast. The construction method of the invention is advantageous in that before data collection and data processing, the engineering geological condition of the tunnel can be basically grasped; the data processing should be objectives-oriented, and then the advanced geological forecast can be accurately conducted; the primary engineering geological problems of the tunnel and the influence of the problems to the tunnel can be estimated, and thereby suggestions of how to deal with the problems can be made in the manner of being geared to engineering practice; the technical advantages of TRT can be fully developed, and the construction progress and safety can be well guaranteed.

Description

technical field [0001] The invention belongs to the technical field of geological prediction, in particular to a construction method for advanced geological prediction. Background technique [0002] In recent years, with the country's massive investment in infrastructure, water conservancy projects, highway projects, and railway projects are all developing by leaps and bounds. A large number of tunnel projects have emerged during the construction of these infrastructures. Due to the limitation of survey technology and survey funds in the geological survey work in the early stage of construction, it is difficult to accurately predict the location, nature and scale of geological disasters that may occur during tunnel construction. With the gradual development of tunnel construction, accidents such as water inrush, mud inrush, collapse, and water environment impact occur frequently. Therefore, it is necessary to carry out advanced geological prediction during tunnel constructio...

Problems solved by technology

[0004] At present, the application of TRT technology in China mostly focuses on the operation and use of equipment, simple and mechanical operation of TRT equipment, step by step according to the operation manual of the equipment, and ignores the macroscopic understanding of tunnel engineering geological conditions by engineering geological professional technicians Therefore, misjudgments and missed judgments often occur in the process of tunnel geological prediction, and it is not only difficult to effectively play the due role of tunnel geological prediction. , and to a large extent restrict the popularization and application of this advanced technology
