Abstract

The invention relates to a geological forecasting method, in particular to an advanced geological forecasting method for a moraine layer tunnel. The method comprises the following steps of: advanced horizontal drilling; collecting information; performing professional judgment which comprises water and mud burst possibility interpretation, high ground temperature possibility interpretation, soft rock deformation possibility interpretation, rockburst possibility interpretation and other geological disease interpretation; designing a unit; performing dynamic design; carrying out construction; and carrying out post-construction confirmation and re-checking on a forecast result. The advanced geological forecasting method for the moraine layer tunnel mainly adopts horizontal drilling for forecasting, is suitable for moraine layers, and is accurate in forecasting and low in cost.

Description

technical field [0001] The invention relates to a geological prediction method, in particular to a method for advanced geological prediction of a moraine layer tunnel. Background technique [0002] Geological forecasting is to find out the hidden major geological problems that are difficult to detect due to the limitations of the previous geological survey work, predict the adverse geological disasters in front of the construction tunnel face, and then correctly guide the safe construction of the tunnel project and reduce the occurrence of geological disasters. probability and risk. [0003] Advanced geological prediction mainly includes methods such as advanced pilot pit and advanced drilling. These methods have long construction period and high cost. The moraine layer is more complex, and the existing advanced geological prediction methods cannot meet the prediction requirements. Contents of the invention [0004] In order to solve the above problems, the present inven...
