[0036] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
[0037] To address the current lack of a more accurate method for locating tunnel anomalies, this invention provides a method for measuring variables using the equivalent back flux transient electromagnetic method, such as... Figure 1 As shown, the method includes:
[0038] S101. Spectral data for determining the target point location based on the equivalent reverse flux transient electromagnetic instrument;
[0039] For example, in this application embodiment, the equivalent reverse flux transient electromagnetic method of the equivalent reverse flux transient electromagnetic instrument is used to confirm the location of the target point, and the position of the receiving antenna is adjusted manually or by machine to obtain the spectrum data of the target point.
[0040] S102. Obtain the two-dimensional cross-sectional view of the above target points;
[0041] For example, visible resistivity data is determined based on an equivalent reverse flux transient electromagnetic instrument. A visible resistivity profile can be constructed based on the visible resistivity data. A three-dimensional visible resistivity profile can be constructed based on at least three sets of visible resistivity data. The three-dimensional visible resistivity profile can assist in determining a three-dimensional cross-sectional slice of the target point. Finally, a two-dimensional cross-sectional view of the target point can be determined based on the three-dimensional cross-sectional slice of the target point.
[0042] The embodiments of this application can use spectral data and two-dimensional cross-sectional diagrams for mutual verification, which improves the reliability of the interpretation results of the equivalent reverse magnetic flux transient electromagnetic instrument, and thus facilitates more accurate delineation of the location of abnormal geological features.
[0043] S103. Determine abnormal geological conditions based on the spectral data and two-dimensional cross-sectional diagrams of the aforementioned target locations.
[0044] By employing the above technical solution, the equivalent back flux transient electromagnetic method variable measurement method provided by this invention addresses the current lack of a more accurate method for locating tunnel anomalies. This invention determines the spectral data of the target location based on the equivalent back flux transient electromagnetic instrument; obtains a two-dimensional cross-sectional view of the target location; and determines the abnormal geological features based on the spectral data and the two-dimensional cross-sectional view. In this solution, the equivalent back flux transient electromagnetic technology can economically, quickly, and accurately determine the spectral data of the target location. Based on understanding the geomorphological characteristics of the target location, mapping work is carried out to study the target location. Combined with the target location's planar position, burial depth range, and excavation profile, it assists in the precise location of abnormal geological features at the target location, providing geological evidence for planning and construction departments.
[0045] In one embodiment, the method further includes: determining the target location based on the excavation direction of the target tunnel segment.
[0046] For example, the target tunnel segment mentioned above can be a tunnel segment that is being excavated, and the end of the excavation direction of the target tunnel segment is the target point. This application embodiment obtains the spectral data and two-dimensional cross-sectional diagram of the end of the excavation direction of the tunnel segment being excavated, and verifies in real time whether there are abnormal geological conditions in the unexcavated tunnel segment, so as to provide the planning and construction department with the location of unfavorable geological conditions in the excavation direction.
[0047] In one embodiment, the spectral data for determining the target point location based on the equivalent reverse flux transient electromagnetic instrument includes:
[0048] Obtain the received signal from the equivalent reverse flux transient electromagnetic instrument;
[0049] The above-mentioned spectrum data is determined based on the received signal.
[0050] For example, in this application embodiment, the transmitting device of the equivalent reverse flux transient electromagnetic instrument continuously transmits signals and acquires the received signals of the receiving device. The received signals are processed based on high-density resistivity method data inversion software to determine the spectral data of the target point.
[0051] It is understandable that before the above steps of processing the received signal based on the high-density resistivity method data inversion software to determine the spectral data of the target point, it is necessary to first remove noise data from the received signal. After the noise data removal step is completed, forward simulation is performed through a pre-set initial model, and then inversion processing is performed to finally determine the spectral data of the target point.
[0052] In one embodiment, determining the spectrum data based on the received signal includes:
[0053] The received signal is converted into resistivity data;
[0054] The resistivity data above is subjected to Gaussian filtering and gridding to determine the spectral data.
[0055] For example, in this application embodiment, the continuous resistivity data is obtained, and the continuous resistivity data is gridded and Gaussian filtered using general-purpose geographic information system software (such as ArcGIS, Mapgis, etc.) to finally determine the spectrum data.
[0056] In one embodiment, the determination of anomalous geological conditions based on the spectral data and two-dimensional cross-sectional map of the target location includes:
[0057] Obtain spectral data of the excavated tunnel section;
[0058] If the difference between the spectral data of the target location and the spectral data of the excavated tunnel section is greater than a first preset difference value, a two-dimensional cross-sectional view of the excavated tunnel section is determined.
[0059] For example, the excavated tunnel section can clearly identify the spectral data of abnormal and normal geological conditions. The spectral data of the excavated tunnel section can serve as an auxiliary reference for the abnormal geological conditions at the target location. If the difference between the spectral data of the target location and the spectral data of the excavated tunnel section is greater than a first preset difference value, the spectral data of the normal geological conditions of the excavated tunnel section is obtained. The comparison result between the spectral data of the normal geological conditions of the excavated tunnel section and the spectral data of the target location is obtained. If the comparison result is greater than the first preset difference value, it indicates that there may be abnormal geological conditions at the target location. Based on this, a two-dimensional cross-sectional diagram of the excavated tunnel section is determined to assist in more accurately verifying the abnormal geological conditions at the target location.
[0060] In one embodiment, the determination of anomalous geological conditions based on the spectral data and two-dimensional cross-sectional map of the target location includes:
[0061] If the difference between the two-dimensional cross-sectional view of the excavated tunnel section and the two-dimensional cross-sectional view of the target point is greater than the second preset difference value, the natural parameters and above-ground engineering parameters of the target point are obtained.
[0062] For example, if the difference between the two-dimensional cross-sectional view of the normal geology of the excavated tunnel section and the two-dimensional cross-sectional view of the target point is greater than a second preset difference value, the possibility of abnormal geology at the target point can be further verified. Based on this, the embodiments of this application can indirectly determine whether the abnormal spectral data and two-dimensional cross-sectional view of the target point are caused by natural causes or by social causes through the natural parameters and above-ground engineering parameters of the target point.
[0063] In one embodiment, the determination of anomalous geological conditions based on the spectral data and two-dimensional cross-sectional map of the target location includes:
[0064] Given that the above-mentioned above-ground engineering parameters reflect the above-ground engineering parameters of the target location, abnormal geology is determined based on the above-mentioned above-ground engineering parameters and natural geological parameters, wherein the above-mentioned natural parameters include hydrological parameters and geological parameters.
[0065] For example, this application embodiment is associated with a city operation work order. This work order can obtain above-ground engineering parameters. If the above-ground engineering parameters indicate that construction exists at the target location, it suggests that the abnormal geology at the target location is caused by the above-ground construction. If the above-ground engineering parameters indicate that there is no construction at the target location, by combining the hydrological and geological parameters of the target location, it can be determined that there is naturally adverse geological condition at the target location. This serves to assist the construction unit in identifying the adverse geological causes in unexcavated areas.
