Abstract
The invention discloses a geological forecast apparatus, wherein the geological forecast apparatus comprises: an electrode for powering geologic mass of a base course; a measuring device for measuringmain current that flows through a main bearing, and a main voltage value between a main voltageelectrode and a main voltagereference electrode; a main unit connected with the electrode and the measuring device through a wire, wherein the main unit is used for calculating, according to the main current and main voltage value detected under different frequencies, apparent resistivity and percentfrequency effect value under the different frequencies so as to determine geological state of the geological mass. The technical problem of the prior art is solved that low measuring precision of a measurement method, which is based on hardware focusing or which uses no focusing, on a shield tunnelingmachine causes inaccuracy of geological forecast results.
Description
technical field [0001] The invention relates to the technical field of geological surveying, in particular to a geological forecasting device. Background technique [0002] With the development of large-scale infrastructure projects such as domestic railways, highways and water conservancy projects and the improvement of the ability of shield machine manufacturers to independently develop shield machines, the proportion of shield tunnel construction in tunnel construction is increasing. The shield machine is a tunnel boring machine that uses the shield method. During the use of the current shield machine, when it encounters water-bearing structural geology such as broken zones, karst caves, and underground rivers, it often causes water inrush disasters, which in turn leads to Machine damage, project delay, and even serious accidents such as casualties. In order to prevent the occurrence of water inrush disasters and ensure the safety of personnel and equipment during shield...
