Description

Technical Field

[0002] As an important part of water conservancy projects, dams have made extremely important contributions to human production and national economic development. With the increase in the number of days that dams are in operation, and the influence of factors such as construction quality and poor geological structure, the hidden dangers of dams in various aspects are becoming increasingly severe, and catastrophic accidents caused by dam leakage are common.

Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on the structures shown in these drawings without paying any creative work.

[0058] Figure 1 This is a flow chart of the first embodiment of a real-time monitoring method for geological anomalies in dams proposed by the present invention. DETAILED DESCRIPTION

[0059] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0060] The present invention provides a real-time monitoring method and system for geological anomalies of dams.

[0061] As attached Figure 1 As shown, in one embodiment of a real-time monitoring method for dam geological anomalies proposed by the present invention, this embodiment is applied to a real-time monitoring system for dam geological anomalies; the system includes a geological anomaly monitoring module, a geological anomaly monitoring host, a monitoring terminal, and a server; the geological anomaly monitoring module is communicatively connected to the geological anomaly monitoring host; the geological anomaly monitoring host and the monitoring terminal are both communicatively connected to the server; the geological anomaly monitoring module includes a plurality of detection electrodes; this embodiment includes the following steps:

[0062] Step S110: Acquire the detection area of the dam to be monitored.

[0063] Step S120: Determine the detection points of the area to be measured, wherein the detection points correspond to the detection electrodes one-to-one, the detection electrodes are embedded in the corresponding detection points, and the detection points are arranged in a straight line at equal intervals within the area to be measured, and the line connecting the detection points in the same area to be measured is perpendicular to the length direction of the dam.

[0064] Specifically, after the detection electrode is embedded in the ground, it is used to detect the electric field component of the dam stratum.

[0065] Step S130: obtaining, through the geological anomaly monitoring host, electric field components detected by each detection electrode at a plurality of different detection frequencies.

[0066] Specifically, based on the frequency domain electromagnetic sounding method, the electric field components detected by each detection electrode at multiple different detection frequencies are obtained; the working principle of the frequency domain electromagnetic sounding method (natural electric field frequency selection method) is mainly: different detection frequencies correspond to different depths of the ground, and the higher the detection frequency, the shallower the corresponding detection depth; the lower the detection frequency, the deeper the corresponding detection depth.

[0067] The source of the natural electric field frequency selection method is the earth electromagnetic field and the alternating electromagnetic field. The field distributed on the ground far away from the field source can be regarded as a plane wave, and its distribution direction is approximately perpendicular to the ground. The change of the field obeys the Maxwell equations. By solving the general wave equation, the relationship between wave impedance and the AC resistivity of the medium can be derived: the penetration depth of electromagnetic waves is related to frequency and resistivity. When the frequency is constant, the higher the resistivity, the greater the penetration depth; when the resistivity is constant, the lower the frequency, the greater the penetration depth.

[0068] Therefore, the purpose of changing the detection depth can be achieved by changing the detection frequency. Since the magnetic field distribution is basically stable within a small range in the same area and can be regarded as a constant, the qualitative relationship between the electric field component and the resistivity can be used to judge the high and low resistance characteristics of the geological body.

[0069] The detection frequency of the geophysical probe is a frequency with the characteristics of the magnetotelluric field, and the spectrum of the magnetotelluric field is between 0.001HZ and 10HZ. According to the actual needs of geological problems, the operating frequency between 10HZ and 3000HZ is generally selected. The frequency interval is evenly distributed on the logarithmic coordinate paper to achieve the purpose of detecting different depths.

[0070] Step S140: determining whether geological anomalies occur in the area to be measured based on the detected electric field components.

[0071] Specifically, when the natural electric field frequency selection method is used for geological exploration, when there is a horizontally electrically inhomogeneous body on the surface or near the surface (i.e., a geological anomaly body. In this embodiment, the geological anomaly that occurs in the dam is generally a cavity or undercurrent inside the dam), the earth current density near the surface or near the surface will increase or decrease, which is specifically manifested as an upward or downward shift of the electric field component curve detected by the detection electrode, but the apparent resistivity curve shape and phase curve will not change. This is the static effect. Based on the characteristic that when a geological anomaly body appears, the electric field component curve detected by the detection electrode will shift upward or downward, it can be judged whether a geological anomaly body appears in the area to be tested.

[0072] If so, execute step S150: generate, by the server, first warning information for indicating that a geological anomaly has occurred in the dam.

[0073] Specifically, if geological anomalies occur in the strata of the dam, it indicates that there may be geological cavities, undercurrents, crustal changes, geological subsidence, rat holes, ant holes, etc. inside the dam, that is, the stratum structure of the dam is risky and requires timely warning and processing; therefore, the first warning information is generated through the server to indicate that there is a geological anomaly in the dam.

[0074] Specifically, the first warning information here includes the location of the dam where the geological anomaly occurs, and the time when the geological anomaly occurs.

[0075] Step S160: Send the first warning information to the monitoring terminal, and display it through the display module of the monitoring terminal.

[0076] The real-time monitoring method for geological anomalies of dams proposed in the present invention can perform real-time geological detection on the strata of the dam based on the geological anomaly monitoring module and the geological anomaly monitoring host. Not only is the monitoring range larger, but the monitoring cycle is shorter, and minute-level monitoring can be achieved, so the monitoring effect is better; and the present invention uses the geological anomaly monitoring module and the geological anomaly monitoring host to perform real-time geological detection on the strata of the dam, which can effectively monitor the internal structure of the dam, such as crustal changes, geological subsidence, rat holes, ant holes, etc., and can more accurately and timely reflect the safety of the dam, and achieve more efficient dam safety early warning.

[0077] In a second embodiment of a real-time monitoring method for geological anomalies in dams proposed by the present invention, based on the first embodiment, the system further includes a piezometer communicatively connected to the server; this embodiment further includes the following steps:

[0078] Step S210: obtaining water pressure data collected by a piezometer installed on the dam to be monitored.

[0079] Step S220: Generate real-time infiltration line data of the dam to be monitored based on the water pressure data via the server.

[0080] Specifically, the seepage line is the intersection of the seepage water surface and the cross-section of the earth dam. The soil below this line is saturated, with the weight of the particles being the effective weight. Simultaneously, it is subject to the seepage force of the seepage water. Therefore, the height and shape of the seepage line within the dam significantly influence the stress of the dam, the shear strength of the soil, the stability of the dam slope, and the seepage stability of the soil. Determining its location is a key component of seepage and stability analysis of earth dams.

[0081] Step S230: Compare the real-time infiltration line data with the standard infiltration line data to determine whether the dam to be monitored has a risk of dam failure.

[0082] Specifically, if the real-time seepage line data is greater than the standard seepage line data, it means that the dam to be monitored has a risk of dam collapse.

[0083] If so, execute step S240: generate, by the server, a second warning message indicating that the dam has a risk of collapse.

[0084] Step S250: Send the second warning information to the monitoring terminal, and display it through the display module (such as a display) of the monitoring terminal.

[0085] In this embodiment, the water pressure data of the stratum of the dam is collected by a piezometer, thereby calculating the real-time infiltration line data, and using it to determine whether the monitored dam has the risk of dam failure.

[0086] In a third embodiment of a real-time monitoring method for geological anomalies in a dam proposed by the present invention, based on the second embodiment, the system further includes a water level gauge in communication with the server; the water level gauge is disposed in an outer river or inner reservoir of the dam; this embodiment further includes the following steps:

[0087] Step S310: Acquire the real-time water level collected by the piezometer installed on the dam to be monitored.

[0088] Step S320: The server determines whether the real-time water level exceeds the flood level.

[0089] If so, execute step S330: generate, by the server, a third warning message indicating a flood situation at the dam.

[0090] Step S340: Send the third warning information to the monitoring terminal, and display it through the display module of the monitoring terminal.

[0091] Specifically, if the real-time water level exceeds the flood level, it means that the reservoir or external river has entered the flood season and a timely warning is needed.

[0092] In a fourth embodiment of a real-time monitoring method for geological anomalies in a dam proposed by the present invention, based on the third embodiment, the system further includes a water flow sensor communicatively connected to the server; the number of the water flow sensors is multiple, and the multiple water flow sensors are evenly distributed in the outer river or inner reservoir of the dam to be monitored; the water flow sensors are used to detect water flow speed and direction; this embodiment also includes the following steps:

[0093] Step S410: Acquire the real-time water flow vector collected by the water flow direction sensor, wherein the real-time water flow vector is collected once every first preset time period.

[0094] Specifically, the first preset duration here is preferably 10 seconds.

[0095] Step S420: The server calculates a water flow vector of a single location within a second preset time period based on the real-time water flow vector, where the second preset time period includes N first preset time periods. The water flow vector of the single location within the second preset time period is calculated as follows:

[0096]

[0097] Where, is the water flow vector of a single position within the second preset time period in the past, is the real-time water flow vector corresponding to the first preset duration i within the past second preset duration, x i is the flow distance of the water flow in the X-axis direction during the i-th first preset time period within the past second preset time period, y i It is the flow distance of the water in the Y-axis direction during the i-th first preset time period within the past second preset time period.

[0098] Specifically, the second preset duration is 60 seconds. For a single-position water flow sensor, the X-axis and Y-axis are perpendicular to each other and are directional axes on the horizontal plane; the origin where the X-axis and Y-axis intersect is the horizontal position of the water flow sensor.

[0099] Step S430: Determine whether the extension lines of the water flow vectors at the single positions within the past second preset time period corresponding to the water flow sensors intersect with a circular area with a radius smaller than a preset radius.

[0100] Specifically, the preset radius here is 10 meters.

[0101] If the extension lines of the water flow vectors at a single position within the second preset time period in the past corresponding to each water flow sensor intersect in a circular area with a radius smaller than the preset radius, it means that the position points of each water flow sensor in the reservoir or outer river have a tendency to converge and flow towards the circular area. This is an abnormal situation, indicating that a dark hole is likely to appear in the circular area, causing the water in the reservoir or outer river to converge and flow towards the dark hole, and early warning and investigation are needed.

[0102] If so, execute step S440: generate, by the server, a fourth warning message indicating that a dark hole has appeared in the dam.

[0103] Specifically, the fourth warning information here includes the moment when the dark hole appears in the dam, and the location of the dark hole in the dam (the location of the dark hole is the circular area where the extension lines of the water flow vectors at a single position within the past second preset time period corresponding to each water flow sensor intersect).

[0104] Step S450: Send the third warning information to the monitoring terminal, and display it through the display module of the monitoring terminal.

[0105] Specifically, this embodiment provides a solution for how to provide early warning when a hidden hole appears in a dam.

[0106] In a fifth embodiment of a method for real-time monitoring of geological anomalies in dams proposed by the present invention, based on the fourth embodiment, the system further includes a GNSS receiver communicatively connected to the server; the GNSS receiver is disposed on the dam body to be monitored; this embodiment further includes the following steps:

[0107] Step S510: Acquire the dam horizontal displacement data and dam settlement data collected by the GNSS receiver installed on the dam to be monitored.

[0108] Step S520: The server determines whether the following conditions are met: the dam horizontal displacement data is greater than the dam horizontal displacement warning value, or the dam settlement data is greater than the dam settlement warning value.

[0109] Specifically, the warning value for horizontal displacement of the dam is 50mm, and the warning value for dam settlement is 12mm.

[0110] If so, execute step S530: generate, by the server, fifth warning information for expressing the risk of dam collapse.

[0111] Step S540: Send the fifth warning information to the monitoring terminal, and display it through the display module of the monitoring terminal.

[0112] Specifically, this embodiment provides a solution for how to provide early warning when abnormal horizontal displacement or abnormal settlement of a dam occurs.

[0113] In a sixth embodiment of a real-time monitoring method for geological anomalies in a dam proposed by the present invention, based on the fifth embodiment, the monitoring terminal further includes an input device (e.g., a keyboard); the system further includes a weather station communicatively connected to the server and disposed at the dam to be monitored; the weather station is configured to obtain real-time weather information of the dam to be monitored, wherein the real-time weather information includes temperature, wind direction, wind speed, relative humidity, precipitation, and atmospheric pressure; the system further includes a camera communicatively connected to the server; the camera is configured to capture a live video of the dam to be monitored; this embodiment further includes the following steps:
