Description

Technical Field

[0001] The present invention belongs to the technical field of slope detection, and in particular relates to a comprehensive electric field detection method, storage medium, equipment and system for a slope pipe flow channel. Background Art

[0002] The instability and destruction of highway slopes are often closely related to groundwater. In recent years, many highway slopes have suffered heavy rainfall in a short period of time, resulting in frequent landslides, which not only caused great economic losses, but also endangered the lives of the people. Among them, pipe flow is an important factor leading to slope instability and destruction. The pipe flow channel refers to the connecting channel formed inside the slope under the influence of gravel and large particles in the soil layer, which allows groundwater to flow out from the inside of the slope in a relatively concentrated manner. When the geological conditions of the slope change or a small collapse occurs inside the slope, the pipe flow channel may be blocked, causing groundwater to spread around the slope. This causes the pores in the surrounding soil to be filled with water, resulting in a decrease in the shear strength of the soil, a decrease in the friction resistance between soil particles, an increase in the electrical conductivity of the soil, etc., which in turn increases the possibility of slope instability and destruction. This not only seriously threatens the stability of the highway, but also endangers the lives of the people and causes serious losses to the country. Therefore, the detection of groundwater on the slope is particularly important.

[0003] In the prior art, the main methods for detecting groundwater in slopes include drilling, exploration wells, cave exploration, active source electric field method and passive source electric field method. Among them, drilling, exploration wells and cave exploration mainly judge the stable water level through boreholes, shafts, etc.; however, since drilling, exploration wells and cave exploration are usually carried out in holes, they can only reflect the initial water level and stable water level at individual locations, and cannot intuitively and systematically reflect the comprehensive changes in the overall area of ​​the slope. Therefore, drilling, exploration wells and cave exploration cannot effectively detect the distribution and flow direction of groundwater in the slope; the active source electric field method mainly judges the distribution position of underground water bodies through low-resistance areas. When the groundwater level of the slope is high, the active source electric field method can detect and reflect a large area of ​​low-resistance areas and judge the distribution position of underground water bodies. However, the active source electric field method cannot accurately judge the location of water-conducting fractures, so it cannot reflect the flow process of water flow; the passive source electric field method mainly captures water flow information through the potential difference generated by the filtering and adsorption of rocks or soil, and judges the flow direction of groundwater. However, the passive source electric field method is greatly affected by climatic conditions and topography, which ultimately makes the measured data unstable, thereby affecting the accuracy of slope detection; Therefore, there is an urgent need for a detection method for slope pipe flow channels. Summary of the invention

[0004] The first purpose of the present invention is to overcome the shortcomings of the prior art and provide a comprehensive electric field detection method for slope pipe flow channels. This method, through the combination of active source electric field method and passive source electric field method, can comprehensively judge the distribution position of slope water bodies and the migration law of groundwater, thereby accurately detecting the distribution of pipe flow channels under the slope and improving the accuracy of slope groundwater detection results.

[0005] A second object of the present invention is to provide a storage medium.

[0006] A third object of the present invention is to provide a computer device.

[0007] The fourth object of the present invention is to provide a comprehensive electric field detection system for slope pipe flow channels.

[0008] The first object of the present invention can be achieved by adopting the following technical scheme:

[0009] A comprehensive electric field detection method for a slope pipe flow channel comprises the following steps:

[0010] S1, obtaining the initial potential data of the bottom soil space of the slope area to be measured during the entire rainfall period; the initial potential data includes active source potential signal data and natural potential signal data;

[0011] S2, preprocessing the acquired active source potential signal data and natural potential signal data to obtain the preprocessed active source potential signal data and natural potential contour map;

[0012] S3, performing inversion analysis on the pre-processed active source potential signal data to obtain resistivity information corresponding to the bottom soil space of the slope area to be measured, and then drawing a resistivity profile of the bottom soil space of the slope area to be measured according to the resistivity information;

[0013] S4, analyzing the pipe flow distribution data of the slope area to be measured according to the resistivity profile and the natural potential contour map combined with the corresponding geological structure characteristics of the slope area to be measured; the pipe flow distribution data includes the plane position of the pipe flow, the pipe flow depth and the pipe flow direction path;

[0016] Preferably, the preprocessing in step S2 is denoising and filtering.

[0017] Preferably, the process of obtaining the pipe flow plane position and pipe flow depth in step S4 is as follows:

[0018] Due to the influence of surface water and mountain water flow before and after precipitation, the water content inside the slope to be measured is different. Therefore, by analyzing the change in resistivity of the resistivity profile of the slope to be measured during the entire rainfall period, the change in water content in each area inside the slope to be measured can be located. The change in water content in each area inside the slope to be measured can be used to determine whether there is a seepage channel in the slope to be measured, and then the pipe flow plane position and pipe flow depth of the slope to be measured can be inferred.

[0019] Preferably, the principle of obtaining the pipe flow direction path in step S4 is as follows:

[0020] Due to the influence of filtration-adsorption during the flow of water in the slope, the natural potential of the seepage channel area inside the slope will change significantly, and the natural potential of the seepage channel area will increase significantly. Therefore, when obvious "convex" contour lines appear in the natural potential contour map of the slope to be measured, it indicates that there is a seepage channel in the slope to be measured, thereby obtaining the water flow direction information of the slope to be measured. By analyzing the water flow direction information of the slope to be measured, the pipe flow path of the slope to be measured can be obtained.

[0021] Preferably, in step S5, the pipe flow area in the bottom soil space of the slope area to be measured is located by the pipe flow plane position, pipe flow depth and pipe flow direction path corresponding to the area.

[0043] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions 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, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0044] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0045] In the description of the present invention, it is necessary to understand that the orientations or positional relationships indicated by the terms "upper", "lower", "top", "bottom", "inside", "outside", etc. are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0046] Example:

[0047] In the description of the present invention, it should be noted that, unless otherwise clearly specified and agreed, the terms "setting", "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] A comprehensive electric field detection method for a slope pipe flow channel comprises the following steps:

[0049] S1, obtaining the initial potential data of the bottom soil space of the slope area to be measured during the entire rainfall period; the initial potential data includes active source potential signal data and natural potential signal data;

[0050] Specifically, the entire rainfall period is from two hours before the rainfall to two hours after the rainfall.

[0051] S2, preprocessing the acquired active source potential signal data and natural potential signal data to obtain the preprocessed active source potential signal data and natural potential contour map;

[0052] Specifically, the preprocessing in step S2 is to perform denoising and filtering operations on the active source potential signal data and the natural potential signal data. This setting facilitates the removal of interference items in the active source potential signal data and the natural potential signal data, thereby improving the accuracy of the comprehensive electric field detection method for the slope pipe flow channel.

[0053] S3, performing inversion analysis on the pre-processed active source potential signal data to obtain resistivity information corresponding to the bottom soil space of the slope area to be measured, and then drawing a resistivity profile of the bottom soil space of the slope area to be measured according to the resistivity information;

[0054] S4, analyzing the pipe flow distribution data of the slope area to be measured according to the resistivity profile and the natural potential contour map combined with the corresponding geological structure characteristics of the slope area to be measured; the pipe flow distribution data includes the plane position of the pipe flow, the pipe flow depth and the pipe flow direction path;

[0055] Specifically, the process of obtaining the pipe flow plane position and pipe flow depth is as follows:

[0056] Due to the influence of surface water and mountain water flow before and after precipitation, the water content inside the slope to be measured is different. Therefore, by analyzing the change in resistivity of the resistivity profile of the slope to be measured during the entire rainfall period, the change in water content in each area inside the slope to be measured can be located. The change in water content in each area inside the slope to be measured can be used to determine whether there is a seepage channel in the slope to be measured. For example, the resistivity value of the slope to be measured is high before rainfall, and the water content is poor; the resistivity value of a local area of ​​the slope to be measured will gradually decrease during rainfall, indicating that the area is gradually filled with water; after rainfall, the slope to be measured presents a large area of ​​low resistance in this area, and the water content is high. Therefore, it can be inferred that the main source of water in this area is rainwater infiltration, and then the pipe flow plane position and pipe flow depth of the slope to be measured can be inferred.

[0057] Specifically, the principle of obtaining the pipe flow direction path in step S4 is as follows:

[0058] Due to the influence of filtration-adsorption during the flow of water in the slope, the natural potential of the seepage channel area inside the slope will change significantly, and the natural potential of the seepage channel area will increase significantly. Therefore, when obvious "convex" contour lines appear in the natural potential contour map of the slope to be measured, it indicates that there is a seepage channel in the slope to be measured, thereby obtaining the water flow direction information of the slope to be measured. By analyzing the water flow direction information of the slope to be measured, the pipe flow path of the slope to be measured can be obtained.

[0059] S5. Obtain the pipe flow area in the bottom soil space of the slope area to be measured through the pipe flow distribution data.

[0060] Specifically, the plane position, depth and flow path of the pipe flow can be reflected in the resistivity profile and the natural potential contour map respectively, so obtaining the plane position, depth and flow path of the pipe flow channel can locate the area of ​​the perfusion channel in the slope.
