[0002] In the railway industry, determining the deformation state of track slabs and the undercarriage heave condition of tunnels is crucial for analyzing the distribution and causes of track defects. However, current technologies typically employ track inspection trolleys and integrated inspection trains to detect track geometry and obtain deformation data for track quality evaluation, thereby guiding line maintenance and repair operations. This approach does not involve detecting track slab deformation and tunnel undercarriage heave conditions to analyze the extent and causes of tunnel defects. In other words, existing technologies lack effective methods for detecting track slab deformation and tunnel undercarriage heave conditions. Summary of the Invention

In the detailed description of the present application below, certain specific details are described in detail. Those skilled in the art can fully understand the present application without these details.

[0044] Furthermore, those skilled in the art should understand that the accompanying drawings provided herein are for illustrative purposes only and are not necessarily drawn to scale.

[0045] Unless the context explicitly requires it, words such as "including" or "contains" throughout the application should be interpreted as including rather than exclusive or exhaustive; that is, meaning "including but not limited to".

[0046] In the description of this application, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0047] Figure 1This is a flowchart of a tunnel floor heave state identification method according to an embodiment of the present invention. Figure 1 As shown, the tunnel floor heave status identification method of this embodiment includes the following steps:

[0048] Step S110: Determine the out-of-limit sections of the target section. The target section is the track segment to be detected, and the out-of-limit sections are those sections within the target section where the elevation irregularity value exceeds the out-of-limit threshold.

[0049] In one optional implementation, step S110 may specifically include: obtaining the track type and track elevation irregularity waveform of the target section; determining the over-limit threshold corresponding to the target section based on the track type; and determining the over-limit section based on the track elevation irregularity waveform and the over-limit threshold. Optionally, the section corresponding to the portion of the track elevation irregularity waveform that exceeds the over-limit threshold can be determined as the over-limit section. A pre-configured correspondence exists between the track type and the over-limit threshold.

[0050] Step S120: Obtain the track parameters of the over-limit section. The track parameters include: elevation irregularity waveform, track alignment irregularity waveform, horizontal irregularity waveform, triangular pit irregularity waveform, track slab gap thickness, and / or center ditch shape.

[0051] Optionally, step S120 may specifically include: detecting various geometric parameters of the track, such as track height, track gauge, track slab gap thickness, and center drainage ditch image, using a track inspection trolley and / or a comprehensive inspection train, and calculating the track parameters of the over-limit section based on these geometric parameters. The track inspection trolley is a portable track geometry measurement device equipped with gauge, level, and other measuring devices, capable of continuously collecting track geometry parameters during manual pushing. The comprehensive inspection train is a large-scale comprehensive inspection equipment based on a high-speed train, capable of comprehensively inspecting parameters such as track, overhead contact line, and signaling at high speeds.

[0052] Figure 2 This is a schematic diagram of the cross-section of a single-bore, double-track tunnel according to an embodiment of the present invention. Figure 2 As shown, in a single-bore double-track tunnel, the tracks include an upward track 21 and a downward track 22, which are located above the tunnel bottom invert 23 and separated by a central drainage ditch 24. For a single-sided track (i.e., the upward track 21 or the downward track 22), its specific structure from top to bottom consists of a track slab 25, a leveling layer 26, and a tunnel bottom filling layer 27. The aforementioned track slab gap, which is the gap between the track slab 25 and the leveling layer 26, can be understood as follows: the track slab has inner and outer sides (the inner side of the track slab is the side closer to the central drainage ditch 24), and the track slab gap is also divided into an inner track slab gap and an outer track slab gap.

[0053] Track unevenness refers to the vertical unevenness of a single rail along its length. Each track slab has two rails; therefore, the unevenness waveform includes an inner unevenness waveform and an outer unevenness waveform. The unevenness waveform is mainly used to determine the degree of camber in the track slab. By comparing the inner and outer unevenness waveforms, the height difference between the inner and outer rails can also be determined. In step S110, when determining the over-limit section based on the unevenness waveform, the unevenness waveform can be the average of the inner and outer unevenness waveforms, or it can be calculated based on either the inner or outer unevenness waveform.

[0054] Track irregularities refer to the lateral unevenness along the length of the inner surface of the rail head (rail head), i.e., the lateral offset of the inner surface of the rail head from the design centerline. In this embodiment, a positive track irregularity value indicates that the track slab is deflected towards the inside of the tunnel, while a negative value indicates that the track slab is deflected towards the outside of the tunnel. Similar to elevation irregularities, track irregularities are also divided into inner track irregularities and outer track irregularities.

[0055] The horizontal unevenness of the track refers to the height difference between the top surfaces of the left and right rails on the same cross section of the track. In this embodiment, the horizontal unevenness value is the height of the inner rail minus the height of the outer rail. A negative horizontal unevenness value indicates that the track slab is tilted outward, while a positive horizontal unevenness value indicates that the track slab is tilted inward.

[0056] The triangular irregularity of a track, also known as torsional irregularity, refers to the twisting of the top surfaces of the left and right rails relative to the track plane. It is measured by the algebraic difference of the horizontal amplitudes of two cross-sections spaced a certain distance apart. The triangular irregularity characterizes the magnitude of the track slab's tendency to twist to one side. In this embodiment, a positive triangular irregularity indicates a tendency for the track slab to deflect outwards, and the larger the positive value, the faster the deflection speed. Conversely, a negative triangular irregularity indicates a tendency for the track slab to deflect inwards, and the smaller the negative value, the faster the deflection speed. Therefore, the change in the triangular irregularity waveform from positive to negative indicates that the track slab first deflects outwards and then returns to its normal position. In other words, the triangular irregularity waveform can characterize the tilt direction of the track slab and the start and end points of the twisted section.

[0057] The separation of the track slab includes the inner separation of the track slab and the outer separation of the track slab, which respectively represent the gaps between the inner and outer sides of the track slab and the leveling layer. Under normal circumstances, the thickness of the inner separation of the track slab is the same as that of the outer separation of the track slab. When the track slab deflects outward, the degree of extrusion of the outer separation of the track slab is greater than that of the inner separation of the track slab, that is, the reduction value of the outer separation of the track slab is greater than the reduction value of the inner separation of the track slab. Therefore, the thickness of the inner separation of the track slab is greater than the thickness of the outer separation of the track slab. Correspondingly, when the track slab deflects inward, the thickness of the inner separation of the track slab is less than the thickness of the outer separation of the track slab.

[0058] The central drainage ditch is rectangular under normal conditions. When the track slab deflects outward, the upper opening of the central drainage ditch expands outward, resulting in the central drainage ditch deformed into a shape with a wider upper part and a narrower lower part. When the track slab deflects inward, the central drainage ditch is deformed into a shape with a narrower upper part and a wider lower part.

[0059] Therefore, according to one or more of the above track parameters, the spatial distortion form of the track slab can be judged.

[0060] Step S130, determine the spatial distortion form of the track slab according to the track parameters. Optionally, the spatial distortion forms include the first form, the second form, the third form, the fourth form, the fifth form, and the sixth form, which respectively correspond to the track slab in the shape of "eight", "丿一", "一 " shape, "inverted eight" shape, " one" shape, "one丿" shape deformation. It should be understood that the above forms are only exemplary descriptions, and the spatial distortion form of the track slab can also be deformed into other forms. This embodiment does not limit this.

[0061] Specifically, determining the spatial distortion form of the track slab according to the track parameters may include:

[0062] In response to the track parameters indicating that the inner vertical irregularity value of at least one side of the track slab is higher than the outer vertical irregularity value, the track direction irregularity value is negative, the horizontal irregularity value is positive, the triangular depression irregularity waveform changes from positive to negative, the thickness of the inner separation of the track slab is greater than the thickness of the outer separation of the track slab, and / or the central drainage ditch is deformed into a shape with a wider upper part and a narrower lower part, it is determined that at least one side of the track slab deflects outward, that is, the spatial distortion form is the first form, the second form or the third form.

[0063] In response to the track parameters indicating that the inner vertical irregularity value of at least one side of the track slab is lower than the outer vertical irregularity value, the track direction irregularity value is positive, the horizontal irregularity value is negative, the triangular depression irregularity waveform changes from negative to positive, the thickness of the inner separation of the track slab is less than the thickness of the outer separation of the track slab, and / or the central drainage ditch is deformed into a shape with a narrower upper part and a wider lower part, it is determined that at least one side of the track slab deflects inward, that is, the spatial distortion form is the fourth form, the fifth form or the sixth form.

[0064] Among them, the aforementioned at least one track slab refers to the track slab of the upward track, or the track slab of the downward track, or the track slab of both the upward track and the downward track.

[0065] Step S140: Determine the tunnel floor heave state of the over-limit section based on the spatial distortion morphology. The tunnel floor heave state includes the range of the tunnel floor heave and the location where the tunnel floor heave acts. Therefore, determining the tunnel floor heave state of the over-limit section based on the spatial distortion morphology includes: determining the range of the tunnel floor heave in the over-limit section based on the spatial distortion morphology, and determining the location where the tunnel floor heave acts in the over-limit section based on the spatial distortion morphology. It can be understood that the longitudinal range of the tunnel floor heave is consistent with the over-limit section; the range of the tunnel floor heave determined here is the lateral range, that is, determining whether the tunnel floor heave acts on both sides of the track, or only on one side of the up-traffic and down-traffic tracks.

[0066] In one optional implementation, the tunnel floor heave state of the over-limit section is determined based on the spatial distortion pattern, including: determining that floor heave occurs on both sides of the tunnel in response to the spatial distortion pattern being a first or fourth pattern; and determining that floor heave occurs only on the uneven side of the tunnel in response to the spatial distortion pattern being a second, third, fifth, or sixth pattern. Here, "both sides of the tunnel" refers to the up-traffic track and the down-traffic track.

[0067] In one optional implementation, determining the location of the tunnel floor heave in the over-limit section based on the spatial distortion pattern of the track slab includes: determining the location of the tunnel floor heave as the tunnel floor in response to the spatial distortion pattern being a first, second, or third pattern; and determining the location of the tunnel floor heave as the tunnel floor leveling layer in response to the spatial distortion pattern being a fourth, fifth, or sixth pattern.

[0068] This embodiment identifies the sections in the target section where the height and unevenness values ​​exceed the over-limit threshold. It then acquires track parameters such as the height and unevenness waveforms, track-direction unevenness waveforms, horizontal unevenness waveforms, triangular pit unevenness waveforms, track slab gap thickness, and / or the shape of the central drainage ditch in these over-limit sections. Based on these track parameters, it determines the spatial distortion pattern of the track slab and the tunnel floor bulging state of the over-limit sections. Therefore, this embodiment can determine the deformation state of the track slab and the tunnel floor bulging state by analyzing track detection data, thereby providing technical support for identifying the scope of tunnel defects, analyzing the causes of tunnel defects, and proposing solutions to tunnel defects.

[0069] Figure 3 This is a schematic diagram of a tunnel floor bulge state identification process according to an embodiment of the present invention. Figure 3As shown, in this embodiment, the high and low irregular waveforms of the target section are obtained, the over-limit threshold is determined according to the line type of the target section, the over-limit section is determined according to the high and low irregular waveforms and the over-limit threshold, the track parameters of the over-limit section are obtained, the spatial distortion pattern of the track slab is identified based on the track parameters, and the range of the tunnel floor heave and the location of the tunnel floor heave can be determined based on each spatial distortion pattern.

[0070] Figure 4 This is a schematic diagram of an uneven track waveform under the action of a bottom drum, according to an embodiment of the present invention. Specifically, Figure 4 The diagram shows the external elevation irregularities, internal elevation irregularities, external track-direction irregularities, internal track-direction irregularities, horizontal irregularities, and triangular pit irregularities of the track. Figure 4 In the scenario shown, the elevation irregularity value on the outer side is lower than that on the inner side at the same longitudinal position. The elevation irregularity value on the outer side is basically consistent with that on the inner side, both being negative values. The horizontal irregularity value is positive, and the triangular crater irregularity waveform changes from positive to negative. It can be understood that the track irregularity waveform includes the irregularity waveform of the ascending track and the irregularity waveform of the descending track. If both satisfy... Figure 4 As shown, the spatial distortion pattern of the track slab is determined to be the first pattern. If only the irregular waveform of the upward track satisfies... Figure 4 As shown, if the irregularities of the downtrack are below their corresponding thresholds, the spatial distortion pattern is determined to be the second pattern. If only the irregularity waveform of the downtrack meets the criteria... Figure 4 As shown, the irregularities of the upward trajectory are all below the corresponding thresholds, thus determining the spatial distortion pattern as the third pattern.

[0071] If the spatial distortion pattern is the first type, i.e., the track slab deforms in a figure-eight shape, it is determined that floor heave occurs on both sides of the tunnel, and the floor heave acts on the tunnel floor. If the spatial distortion pattern is the second type, i.e., the track slab deforms in a figure-eight shape, it is determined that floor heave occurs on the left side of the tunnel, and the floor heave acts on the tunnel floor. If the spatial distortion pattern is the third type, i.e., the track slab deforms in a figure-eight shape... The deformation indicates that a bottom heave occurred on the right side of the tunnel, and that the bottom heave is acting on the tunnel floor.

[0072] Figure 5 This is a schematic diagram of a tunnel cross-section under the action of a floor drum, according to an embodiment of the present invention. Figure 5 As shown, because the tunnel bottom arch is an inverted arch structure, when the bottom heave acts on the tunnel bottom (i.e., the surrounding rock below the tunnel bottom arch), the upward heave force will preferentially act on the position closer to the inside of the track, causing the track slab to deflect outwards. Depending on the range of the bottom heave's action, it forms a figure-eight shape, a horizontal line shape, or a vertical line shape. "Shapes of the shape." Figure 5Taking the case where floor heave occurs on both sides of the tunnel, that is, the spatial distortion form is the first form (as shown by the dotted line in the figure) as an example for illustration, it should be understood that if floor heave occurs only on the left side of the tunnel in the figure, the corresponding spatial distortion form is the second form, and if floor heave occurs only on the right side of the tunnel, the corresponding spatial distortion form is the third form.

[0073] Figure 6 It is a schematic diagram of the track irregularity waveform under the action of another type of floor heave in an embodiment of the present invention. Specifically, Figure 6 It shows the outer vertical irregularity waveform, inner vertical irregularity waveform, outer alignment irregularity waveform, inner alignment irregularity waveform, horizontal irregularity waveform and twist irregularity waveform of the track. In Figure 6 the shown case, the outer vertical irregularity value at the same longitudinal position is higher than the inner vertical irregularity value, the outer alignment irregularity value and the inner alignment irregularity value are both positive, the horizontal irregularity value is negative, and the twist irregularity waveform shows a change from negative to positive. And, due to the deflection direction of the outer side of the track slab being inconsistent with the deflection direction of the leveling layer below, the outer alignment irregularity value is greater than the inner alignment irregularity value. Similar to the foregoing method, according to the irregularity waveforms of the up and down tracks and Figure 6 it is possible to determine whether the spatial distortion form of the track slab is the fourth form, the fifth form or the sixth form.

[0074] If the spatial distortion form is the fourth form, that is, the track slab is deformed in an "inverted V" shape, it is determined that floor heave occurs on both sides of the tunnel, and the floor heave acts on the leveling layer. If the spatial distortion form is the fifth form, that is, the track slab is deformed in a " one" shape, it is determined that floor heave occurs on the left side of the tunnel, and the floor heave acts on the leveling layer. If the spatial distortion form is the sixth form, that is, the track slab is deformed in a "slanting one" shape, it is determined that floor heave occurs on the right side of the tunnel, and the floor heave acts on the leveling layer.

[0075] Figure 7 It is a schematic diagram of another cross-section of the tunnel under the action of floor heave in an embodiment of the present invention. As Figure 7 shown, when the floor heave action position is the leveling layer, the center of the leveling layer bulges upward. Since the track slab is located on one side of the leveling layer close to the central ditch, when the center of the leveling layer bulges, it will cause the track slab to deflect inward, and according to the different ranges of the floor heave action, deformations in an "inverted V" shape, a "slanting one" shape or a " one" shape are formed. Figure 7 Taking the case where floor heave occurs on both sides of the tunnel, that is, the spatial distortion form is the fourth form (as shown by the dotted line in the figure) as an example for illustration, it should be understood that if floor heave occurs only on the left side of the tunnel in the figure, the corresponding spatial distortion form is the fifth form, and if floor heave occurs only on the right side of the tunnel, the corresponding spatial distortion form is the sixth form.

[0076] In one optional implementation, the tunnel floor heave state identification method further includes: displaying waveforms of various track irregularities, and / or displaying a floor heave image simulated based on track parameters. This embodiment displays such images on a display screen. Figure 4 , Figure 5 , Figure 6 , Figure 7 The test results can assist relevant technicians in monitoring various indicators and the condition of the tunnel floor through visualization, thereby providing technical support for identifying the scope of tunnel defects, analyzing the causes of tunnel defects, and proposing solutions to tunnel defects.

[0077] Figure 8 This is a schematic diagram of the irregular waveform of the downlink track obtained from measurements according to an embodiment of the present invention. The corresponding irregularity values ​​of the uplink track are below their respective thresholds and are not shown here. Figure 8 As shown, within the 200m-280m section of the downhill track, there are two sections of uneven waveforms exceeding the over-limit threshold, thus confirming the existence of two over-limit sections within this area. The positive and negative distribution trends of the track alignment changes on the inner and outer rails are the same, both being positive within the over-limit sections, indicating that the track slab is tilting inwards. Simultaneously, both the horizontal uneven waveform and the triangular irregular waveform show significant fluctuations at the start and end points of the over-limit sections, with the overall trend consistent with... Figure 6 The situation is shown in the figure. Therefore, it can be determined that the spatial distortion pattern of the track slab is the sixth pattern, and further determined that the bottom heave of the tunnel only occurs on the right side of the over-limit section, and the location of the tunnel bottom heave is the leveling layer.

[0078] This embodiment identifies the sections in the target section where the height and unevenness values ​​exceed the over-limit threshold. It then acquires track parameters such as the height and unevenness waveforms, track-direction unevenness waveforms, horizontal unevenness waveforms, triangular pit unevenness waveforms, track slab gap thickness, and / or the shape of the central drainage ditch in these over-limit sections. Based on these track parameters, it determines the spatial distortion pattern of the track slab and the tunnel floor bulging state of the over-limit sections. Therefore, this embodiment can determine the deformation state of the track slab and the tunnel floor bulging state by analyzing track detection data, thereby providing technical support for identifying the scope of tunnel defects, analyzing the causes of tunnel defects, and proposing solutions to tunnel defects.

[0079] Figure 9 This is a schematic diagram of a tunnel floor drum status identification device according to an embodiment of the present invention. Figure 9 As shown, the tunnel floor drum state identification device 9 in this embodiment includes a first determination module 91, a parameter acquisition module 92, a second determination module 93, and a third determination module 94.

[0080] The first determining module 91 is used to determine the over-limit section of the target section. The over-limit section is the section in the target section where the height unevenness value exceeds the over-limit threshold.

[0081] The parameter acquisition module 92 is used to acquire track parameters for the over-limit section. These track parameters include: elevation irregularities, track alignment irregularities, horizontal irregularities, triangular pit irregularities, track slab gap thickness, and / or the shape of the center drainage ditch. Optionally, the parameter acquisition module 92 is also used to acquire the track type of the target section.

[0082] The second determining module 93 is used to determine the spatial twist shape of the track slab based on the track parameters.

[0083] The third determining module 94 is used to determine the tunnel floor heave state of the over-limit section based on the spatial distortion morphology.

[0084] This embodiment identifies the sections in the target section where the height and unevenness values ​​exceed the over-limit threshold. It then acquires track parameters such as the height and unevenness waveforms, track-direction unevenness waveforms, horizontal unevenness waveforms, triangular pit unevenness waveforms, track slab gap thickness, and / or the shape of the central drainage ditch in these over-limit sections. Based on these track parameters, it determines the spatial distortion pattern of the track slab and the tunnel floor bulging state of the over-limit sections. Therefore, this embodiment can determine the deformation state of the track slab and the tunnel floor bulging state by analyzing track detection data, thereby providing technical support for identifying the scope of tunnel defects, analyzing the causes of tunnel defects, and proposing solutions to tunnel defects.

[0085] Figure 10 This is a schematic diagram of an electronic device according to an embodiment of the present invention. (For example...) Figure 10 As shown, Figure 10 The illustrated electronic device is a general-purpose data processing device, comprising a general-purpose computer hardware architecture, including at least a processor 101 and a memory 102.

Thus, the processor 101 executes the instructions stored in the memory 102, thereby performing the method flow of the embodiments of the present invention as described above to process data and control other devices. The bus 103 connects the aforementioned components together and connects them to a computer-interactive display 104 for display and interaction.
