[0055] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0056] The present invention provides a method for early warning of leakage of hidden dangers of dikes, which can effectively warn of dike leakage through probability judgment of natural potential data and monitoring of artificial potential data.

[0057] According to an embodiment of the present invention, an embodiment of a dike leakage warning method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0058] In this embodiment, a method for early warning of leakage of embankment hidden dangers is provided. Figure 1 FIG. 1 is a flow chart of a method for early warning of leakage of levee hidden dangers according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0059] Step S1, laying out a plurality of survey lines parallel to the dike axis, and using the survey lines to obtain natural potential data at dike monitoring points.

[0060] Specifically, due to the existence of cracks, flowing crack water will generate a filtering electric field, and dynamic monitoring of natural potential can be used to identify the evolution of leakage channels. The location of underground charge accumulation can be inverted by the natural potential probability imaging method, and the location and depth of leakage can be quickly estimated.

[0061] like Figure 2 As shown in the figure, the natural potential signal is observed through several measuring lines arranged parallel to the axis of the dike. Then the natural potential data on the measuring line is transmitted to the acquisition terminal through the point method signal transmission cable. The acquisition terminal uploads all the acquired natural potential data to the remote processing terminal through the network.

[0062] Step S2, processing the spontaneous potential data according to the probabilistic imaging method to calculate the location of the suspected leakage channel.

[0063] Specifically, the remote processing terminal compares the current natural potential data with the threshold value. If the natural potential data exceeds the threshold value, a warning is given in time through the display screen or warning light. After the warning is triggered, the remote processing terminal calculates the possible location of underground charge accumulation through a probability calculation method and infers the location of the suspected leakage channel.

[0064] Step S3, applying an artificial electric field to the suspected leakage channel, and obtaining artificial potential data at the embankment monitoring point using a measuring line.

[0065] Specifically, since the natural potential data is easily disturbed by underground stray currents, in order to accurately identify the leakage channel, after receiving the early warning information, an artificial electric field should be established one by one for the suspected leakage channel. Figure 2 As shown in FIG. 1 , after a stable artificial electric field is established, the artificial potential data on the measuring line is transmitted to the acquisition terminal through the point method signal transmission cable. Then the acquisition terminal uploads all the acquired artificial potential data to the remote processing terminal through the network.

[0066] Step S4, producing a line potential curve and a potential gradient curve according to the artificial potential data.

[0067] Specifically, the remote processing terminal synchronously calculates the potential profile and the potential gradient profile on the measuring line according to the artificial potential data, and draws the potential curve and the potential gradient curve of the measuring line.

[0068] Step S5, judging whether the suspected leakage channel is a real leakage channel according to the potential curve and the potential gradient curve.

[0069] Specifically, the line connecting the maximum value of the normalized potential curve and the zero value point of the normalized potential gradient curve on the general cross-sectional plane is the projection position of the leakage channel on the ground. Therefore, when there is a line connecting the maximum value of the normalized potential curve and the zero value point of the normalized potential gradient curve on the cross-sectional plane, the suspected leakage channel is determined to be a real leakage channel.

[0070] The present invention provides a method for early warning of leakage of hidden dangers in levees, including: laying out a plurality of survey lines parallel to the axis of the levee, and using the survey lines to obtain natural potential data at the monitoring points of the levee; processing the natural potential data according to the probability imaging method, and calculating the position of the suspected leakage channel; applying an artificial electric field to the suspected leakage channel, and using the survey lines to obtain the artificial potential data at the monitoring points of the levee; making a survey line potential curve and a potential gradient curve according to the artificial potential data; judging whether the suspected leakage channel is a real leakage channel according to the potential curve and the potential gradient curve. The underground charge accumulation position is inverted by the natural potential probability imaging method to identify the suspected leakage channel. An artificial electric field is applied to the suspected leakage channel to carry out real-time monitoring of the leakage evolution process, and the monitoring results of the artificial electric field and the natural field are compared, so as to accurately determine the leakage position and provide an effective early warning of levee leakage.

[0071] In an optional implementation, step S1 includes:

[0072] Step S11, arranging a plurality of measuring electrodes in parallel at equal intervals at monitoring points of the embankment, and connecting them via transmission cables to form a plurality of measuring lines.

[0073] Step S12, burying the reference electrode in a normal field area far away from the permeation area to be measured and with a stable electric field.

[0074] Step S13, collecting spontaneous potential data at the monitoring point at preset time intervals.

[0075] Specifically, Figure 2 As shown in the figure, multiple measuring electrodes are arranged in parallel at equal intervals on the levee (water-facing surface, back-water surface, and levee top), connected by electrical signal transmission cables to form a path, forming several natural potential observation lines. During measurement, the reference electrode is buried in a normal field area away from the seepage area to be measured and with a stable electric field. The acquisition terminal collects the natural potential data at the monitoring point at a preset time interval. The natural potential data is the potential difference between the measuring electrode and the reference electrode. According to the potential difference between adjacent measuring electrodes, the corresponding potential gradient along the levee direction can be calculated, and the electric field strength can be obtained.

[0076] In an embodiment of the present invention, both the measuring electrode and the reference electrode are non-polarized electrodes to avoid errors in the natural potential measurement caused by electric field polarization. In order to ensure the quality of long-term observation data, the non-polarized electrodes should be equipped with corresponding protective devices. The protective device is a cover body, which is stably buckled on the top of the corresponding non-polarized electrode, and the cover body is made of materials such as polyurethane. The preset time interval is a unique fixed time interval. The acquisition terminal synchronously collects the natural potential data of each electrode position at a fixed time, which can reduce the interference potential generated by industrial stray currents.

[0077] In an optional implementation, step S2 includes:

[0078] Step S21, determining whether the spontaneous potential data exceeds a threshold.

[0079] Step S22, when the spontaneous potential data exceeds a threshold value, a probability imaging function of a line charge model is derived according to the stripe-shaped distribution characteristics of the charge in the leakage zone channel.

[0080] Step S23, comparing the calculation results of the probability imaging functions of different survey lines, analyzing and determining the possible location and depth of the levee leakage channel.

[0081] Specifically, the remote processing terminal compares the current natural potential data with the threshold. If the natural potential data exceeds the threshold, a warning is given in time through the display screen or warning light. After the warning is triggered, the remote processing terminal calculates the possible location of underground charge accumulation through a probability calculation method and infers the location of the suspected leakage channel. The principle of the probability imaging method is as follows:

[0082] A rectangular coordinate system is established, with the X and Y axes in the horizontal plane, the Z axis pointing underground, and the X axis along the embankment axis. The electric field along the X direction on the ground can be expressed as:

[0083]

[0084] Where Γq is the strength of the qth charge, (x q ,y q ,z q ) are the coordinates of the charge.

[0085] Introducing 3D electric field scanning function As follows (SDS function):

[0086]

[0087] The charge probability imaging function (COP function) is defined as follows:

[0088]

[0089] SDS Function It can be regarded as a q ,y q ,z q ), the electric field formed by positive charges with an intensity of 1, and the COP function is a normalized cross-correlation integral, whose absolute value is not greater than 1. Its value distribution is only related to the electric field function, that is, the distribution of underground charges.

[0090] According to the formation mechanism of the filtering electric field, the concentrated leakage channel is abstracted into such an electrical model:

[0091] More negative charges gather at the leakage entrance to form a negative charge body; a certain amount of negative charges gather along the seepage channel, which can be approximately regarded as a linear charge; more positive charges gather at the outlet of the seepage channel to form a positive charge body (for example Figure 3 ).

[0092] According to the strip-shaped distribution characteristics of the charge in the seepage zone channel, the probabilistic imaging method of the line charge model is derived. The electric field along the x direction generated by the line charge Γq on the ground can be expressed as:

[0093]

[0094] Introduce the corresponding scanning function:

[0095]

[0096] The probability imaging function can be derived:

[0097]

[0098] in,

[0099] Therefore, η(x q ,y q ,z q ) is used to describe the distribution of underground charges. Obviously, η(x q ,y q ,z q ) is affected by the concentration of positive charge, while negative values ​​are affected by the concentration of negative charge. q ,y q ,z q ) contour plot, the extreme values ​​can be interpreted as where the charge is most likely to occur.

[0100] Example data and corresponding spontaneous potential probability imaging results are shown in Figure 4(a)-Figure 4(b) , assuming that the positive and negative charges are located at (10, -10) and (-10, -10) respectively, the potential curve observed on the surface is shown in Figure 4(a), and the natural potential probability imaging result is shown in Figure 4(b).

[0101] In an optional implementation, step S3 includes:

[0102] Step S31, arranging a power supply electrode at a suspected leakage channel position, burying a power supply infinity electrode at a symmetrical side of the reference electrode, and supplying power to the power supply electrode and the power supply infinity electrode.

[0103] Step S32, sprinkle salt solution into the water body on the upstream side of the suspected leakage channel area.

[0104] Step S33: collecting artificial potential data at the monitoring point through the measuring line at a preset time interval.

[0105] Specifically, the power supply electrode should be arranged at a known seepage point. When the seepage location is unknown, it should be arranged at the foot of the slope on the back water surface of the dam. In order to ensure the effect of establishing the artificial electric field, the buried depth of the power supply electrode should not be less than the estimated depth of the seepage channel. When the electrode burial depth does not meet the requirements, drilling should be carried out and the electrode should be arranged in the drill hole. The power supply infinity electrode should be buried in an area far away from the symmetrical side of the reference electrode, and the closest distance to the measurement area should generally be no less than 3 times the length of the potential observation line.

[0106] Sprinkle salt solution into the water body on the upstream side of the suspected leakage channel area to enhance the electrical difference characteristics of the leakage channel. The depth of the salt solution should not be less than the estimated depth of the seepage channel. The power supply current should be stable direct current or ultra-low frequency alternating current (≤2Hz) or random signal current.

[0107] Generally, stable direct current is used for power supply and observation. If the stray current interference is large and the observed potential signal is not obvious, ultra-low frequency alternating current (≤2Hz) or pseudo-random signal current with stronger anti-interference ability can be used instead, and the power supply current can be increased.

[0108] By applying an artificial electric field to the suspected leakage channel to carry out real-time monitoring of the leakage evolution process, and by adding salt solution, the electrical difference characteristics caused by the leakage are enhanced, which can achieve long-term dynamic monitoring and effective early warning of hidden dangers of dam leakage.

[0109] In an optional implementation, step S5 includes:

[0110] Step S51, drawing a cross-sectional plane diagram according to the potential curves and potential gradient curves of different measuring lines.

[0111] Step S52: If there is a line connecting the maximum value of the normalized potential curve and the zero value point of the normalized potential gradient curve on the cross-sectional plane diagram, it is determined that the suspected leakage channel is a real leakage channel.

[0112] Specifically, after a stable artificial current field is established, the data acquisition terminal should be used to collect data, and the potential profile and potential gradient profile on the measuring line should be calculated synchronously, and the potential curve and potential gradient curve of the measuring line should be drawn. The observed data should be normalized according to the power supply current, and the potential curves and potential gradient curves of different measuring lines should be drawn into a profile plan. Generally, the line connecting the maximum value of the normalized potential curve and the zero value point of the normalized potential gradient curve on the profile plan is the projection position of the leakage channel on the ground. Therefore, when there is a line connecting the maximum value of the normalized potential curve and the zero value point of the normalized potential gradient curve on the profile plan, the suspected leakage channel is determined to be a real leakage channel. See example potential observation data. Figure 5 .

[0113] In an optional embodiment, the method further comprises the following steps:

[0114] Step S61, comparing the calculation results at different times and analyzing the evolution process of the leakage channel.

[0115] Step S62: When there is a trend of worsening, immediately report and initiate the emergency plan.

[0116] Specifically, by comparing the calculation results at different times and analyzing the evolution process of the leakage channel, long-term dynamic monitoring and effective early warning of dam leakage hazards can be achieved.
