Description
Technical Field
[0001] This invention belongs to the field of traffic tunnel technology, specifically relating to a method and apparatus for determining the load of a traffic tunnel based on vibration measurements. Background Technology
[0002] Traffic tunnel load is one of the important factors in determining the safe operation of traffic tunnels. Current traffic load specifications can be used to predict traffic load, but due to the assumptions and simplifications in existing specifications, there are certain differences between the results and the actual situation. Moreover, existing methods for calculating traffic tunnel load have defects such as large errors or computational complexity. For example, the method of determining traffic tunnel load through vehicle-induced vibration sources is difficult to accurately simulate the vibration characteristics of traffic tunnels and thus determine the traffic tunnel load because various factors such as the type of vehicles in the traffic tunnel will affect the vibration characteristics of the vehicle-induced vibration sources.
[0003] Therefore, accurately determining the load on a traffic tunnel is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention
[0004] The purpose of this invention is to solve the technical problem that existing technologies cannot accurately determine the load on traffic tunnels.
[0005] To achieve the above-mentioned technical objectives, on the one hand, the present invention provides a method for determining the load of a traffic tunnel based on vibration measurements, the method comprising:
[0006] The vibration measurement points and parameters are determined based on the type of traffic tunnel.
[0007] Vibration measurements were performed on the traffic tunnel based on the vibration measurement points and vibration measurement parameters, and vibration measurement data were obtained.
[0008] The load on the traffic tunnel is determined based on the measured vibration data.
[0009] Furthermore, the types of traffic tunnels include highway tunnels and subway tunnels, and the measured vibration parameter is the vibration test time.
[0010] Furthermore, the method includes:
[0011] If the traffic tunnel is a highway tunnel, then the vibration measurement points include the internal cross passage of the highway tunnel, one shoulder of the cross passage and the other shoulder of the cross passage during the nighttime off-peak period, the daytime off-peak period, the daytime peak period, and the nighttime off-peak period.
[0012] If the traffic tunnel is a subway tunnel, then the vibration measurement points include the subway station platform, concourse, and ground level during nighttime off-peak hours, daytime off-peak hours, daytime peak hours, and nighttime off-peak hours.
[0013] Furthermore, determining the load of the traffic tunnel based on the measured vibration data specifically includes:
[0014] Based on the vibration measurement data, a first vibration measurement point that meets the preset conditions is determined;
[0015] The load on the traffic tunnel is determined based on the maximum and effective values of vibration acceleration at the first vibration measurement point.
[0016] Furthermore, the preset conditions specifically include the maximum vibration acceleration value being the largest among all vibration acceleration values corresponding to all vibration measurement points, and the effective vibration acceleration value being the largest among all effective vibration acceleration values corresponding to all vibration measurement points.
[0017] Furthermore, if the traffic tunnel is a highway tunnel, then the maximum vibration acceleration is the largest among the maximum vibration acceleration values corresponding to all vibration measurement points, and the effective vibration acceleration value is the largest among the effective vibration acceleration values corresponding to all vibration measurement points, specifically determined by the following formula:
[0018]
[0019]
[0020] In the formula, max(a m1 ) represents the maximum vibration acceleration at the first measured vibration point in the highway tunnel, max(a r1 () represents the maximum effective value of the vibration acceleration corresponding to the first vibration measurement point in the highway tunnel. These represent the maximum vibration acceleration values during the nighttime low-peak period, daytime low-peak period, daytime peak period, and nighttime peak period, respectively. The values represent the effective values of vibration acceleration during the nighttime low-peak period, daytime low-peak period, daytime peak period, and nighttime peak period, respectively.
[0021] Furthermore, if the traffic tunnel is a subway tunnel, then the maximum vibration acceleration is the largest among the maximum vibration acceleration values corresponding to all vibration measurement points, and the effective vibration acceleration value is the largest among the effective vibration acceleration values corresponding to all vibration measurement points, specifically determined by the following formula:
[0022]
[0023]
[0024] In the formula, max(a m2 ) represents the maximum vibration acceleration at the first measured vibration point in the subway tunnel, max(a r2() represents the maximum effective value of the vibration acceleration corresponding to the first vibration measurement point in the subway tunnel. These represent the maximum vibration acceleration values at the subway platform level, the subway tunnel beneath the platform level, and the ground level, respectively. These represent the effective values of vibration acceleration in the subway tunnels below the platform level, the platform level, and the ground level, respectively.
[0025] On the other hand, the present invention also provides a device for determining the load of a traffic tunnel based on vibration measurements, the device comprising:

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0037] like Figure 1 The diagram illustrates a flow chart of the method for determining the load of a traffic tunnel based on vibration measurements, as provided in the embodiments of this specification. While this specification provides the method operation steps or device structure shown in the embodiments or accompanying drawings, based on conventional methods or without creative effort, the method or device may include more or fewer operation steps or module units after partial merging. In steps or structures where there is no logically necessary causal relationship, the execution order of these steps or the module structure of the device are not limited to the execution order or module structure shown in the embodiments or accompanying drawings of this specification. When the method or module structure is applied in actual devices, servers, or terminal products, it can be executed sequentially or in parallel according to the method or module structure shown in the embodiments or accompanying drawings (e.g., in a parallel processor or multi-threaded processing environment, or even in a distributed processing or server cluster implementation environment).
[0038] The method for determining traffic tunnel loads based on vibration measurements provided in this embodiment can be applied to terminal devices such as client and server devices. Figure 1 As shown, the method specifically includes the following steps:
[0039] Step S101: Determine the vibration measurement points and vibration measurement parameters according to the type of traffic tunnel.
[0040] Specifically, the types of traffic tunnels include highway tunnels and subway tunnels. The vibration measurement parameters are the vibration test time. If the traffic tunnel is a highway tunnel, the vibration measurement points include the internal cross passages, the west shoulder of the cross passages, and the east shoulder of the cross passages during the nighttime off-peak period, the daytime off-peak period, the daytime peak period, and the nighttime off-peak period. If the traffic tunnel is a subway tunnel, the vibration measurement points include the subway station platform level, concourse level, and ground level during the nighttime off-peak period, the daytime off-peak period, the daytime peak period, and the nighttime off-peak period.
[0041] Specifically, to ensure the safety of the testing personnel, vibration measurement points for highway tunnels are arranged at the tunnel's internal cross passage, one shoulder of the cross passage, and the other shoulder of the cross passage. The measurement points in the internal cross passage are arranged from one boundary of the cross passage to the other boundary, such as... Figure 3 The diagram shows the layout of measuring points inside the cross passage of a highway tunnel. The distance between measuring point H1 and measuring point H2 on one side boundary of the cross passage is denoted as s0. The measuring points on the shoulder of the cross passage are arranged starting from the boundary of the cross passage as shown below. Figure 4 The diagram shows the layout of measuring points on one side of a cross passage inside a highway tunnel. Measuring points J1 and JN on one shoulder of the cross passage are placed at measuring points s1 and s2, respectively, at a distance of H1 from the cross passage boundary. Measuring points on the other shoulder of the cross passage are arranged starting from the other side boundary as shown below. Figure 5 The diagram shows the arrangement of measuring points on the other side of the cross passage inside a highway tunnel. By arranging measuring points inside the cross passage, on one shoulder of the cross passage, and on the other shoulder of the cross passage, the characteristics of vehicle-induced vibration sources in highway tunnels in different areas, as well as the characteristics of vehicle-induced vibrations in highway tunnels during off-peak hours at night, off-peak hours during the day, peak hours during the day, and peak hours at night, were determined.
[0042] The subway station consists of three levels from bottom to top: platform level, concourse level, and ground level. 2N, N, and N measuring points were deployed at the platform level, concourse level, and ground level, respectively, to collect vibration data in both vertical and horizontal directions. The measuring points at the platform level were positioned on both sides of the platform, outside the yellow line near the approaching train. The measuring points at the concourse and ground levels were aligned as much as possible with the centers of the two measuring points at the platform level. Through field measurements at these measuring points, the characteristics of vehicle-induced vibration sources in the subway tunnel under different depth conditions, as well as the vibration distribution characteristics along the height of vehicle-induced vibrations in the subway tunnel, were determined.
[0043] Step S102: Perform vibration measurements on the traffic tunnel based on the vibration measurement points and vibration measurement parameters, and obtain vibration measurement data.
[0044] Specifically, after determining the vibration measurement points and vibration measurement time, data sampling is performed using continuous sampling mode at a sampling rate of f. s The number of samples is n, and the channel sensitivity of both the 991B and 941B pickups is set to 0.3. The filter cutoff frequency is f. j The resampling frequency f c Half of it.
[0045] Vibration measurements were conducted on a two-way six-lane highway tunnel and a two-way eight-lane highway tunnel, and the measuring points were arranged according to the measuring point layout plan.
[0046] Step S103: Determine the load of the traffic tunnel based on the measured vibration data.
[0047] In this embodiment of the application, determining the load of the traffic tunnel based on the measured vibration data specifically includes:
[0048] Based on the vibration measurement data, a first vibration measurement point that meets the preset conditions is determined;
[0049] The load on the traffic tunnel is determined based on the maximum and effective values of vibration acceleration at the first vibration measurement point. Specifically, the preset conditions include the maximum vibration acceleration being the largest among all the maximum vibration acceleration values corresponding to all vibration measurement points, and the effective vibration acceleration being the largest among all the effective vibration acceleration values corresponding to all vibration measurement points.
[0050] Specifically, if the maximum value and the effective value appear at the same measuring point, the acceleration time history of that measuring point is selected as the load excitation; if the maximum value and the effective value do not appear at the same measuring point, the measuring point with the largest effective acceleration value is first determined, and the acceleration time history of that measuring point is selected as the load excitation, and that measuring point is taken as the first vibration measurement point; in this way, the load excitation during the nighttime off-peak period is determined by comprehensively considering the maximum value and the effective value of the acceleration time history. By comparing the load excitation of the four different working conditions of the nighttime off-peak period, the daytime off-peak period, the daytime peak period, and the nighttime peak period, the first vibration measurement point that meets the preset conditions is determined. These preset conditions are also the most unfavorable working conditions. Using the load determined by the most unfavorable working conditions can ensure that the load is representative. In this application, the load of the traffic tunnel is the acceleration time history.
[0051] If the traffic tunnel is a highway tunnel, then the maximum vibration acceleration is the largest among the maximum vibration acceleration values corresponding to all vibration measurement points, and the effective vibration acceleration value is the largest among the effective vibration acceleration values corresponding to all vibration measurement points. Specifically, it is determined using the following formula:
[0052]
[0053]
[0054] In the formula, max(a m1 ) represents the maximum vibration acceleration at the first measured vibration point in the highway tunnel, max(a r1 () represents the maximum effective value of the vibration acceleration corresponding to the first vibration measurement point in the highway tunnel. These represent the maximum vibration acceleration values during the nighttime low-peak period, daytime low-peak period, daytime peak period, and nighttime peak period, respectively. The values represent the effective values of vibration acceleration during the nighttime low-peak period, daytime low-peak period, daytime peak period, and nighttime peak period, respectively.
[0055] If the traffic tunnel is a subway tunnel, then the maximum vibration acceleration is the largest among the maximum vibration acceleration values corresponding to all vibration measurement points, and the effective vibration acceleration value is the largest among the effective vibration acceleration values corresponding to all vibration measurement points. Specifically, it is determined using the following formula:
[0056]
[0057]
[0058] In the formula, max(a m2 ) represents the maximum vibration acceleration at the first measured vibration point in the subway tunnel, max(a r2 () represents the maximum effective value of the vibration acceleration corresponding to the first vibration measurement point in the subway tunnel. These represent the maximum vibration acceleration values at the subway platform level, the subway tunnel beneath the platform level, and the ground level, respectively. These represent the effective values of vibration acceleration in the subway tunnels below the platform level, the platform level, and the ground level, respectively.
[0059] In determining the load on a traffic tunnel, this application uses the maximum vibration acceleration (a) as a visual indicator to assess the magnitude of vibration. max for:
[0060] a max =max{a n}
[0061] In the formula, a n It is a discrete vibration acceleration sequence.
[0062] However, there may be instantaneous excitation from external disturbances, leading to a sudden increase. This paper also uses the effective value of acceleration to supplement the shortcomings of using the maximum vibration acceleration to judge the magnitude of the vibration response. The effective value of acceleration a in a traffic tunnel is... rms for:
[0063]
[0064] In the formula, N is the discrete vibration acceleration sequence a n The length.
[0065] For discrete vibration acceleration sequence a n Power spectral analysis (PSD) was performed, and the ω corresponding to the maximum spectral value was selected as the main frequency of the vibration spectrum.
[0066] After determining the main frequencies mentioned above, the time history of the vibration response can be obtained when performing finite element analysis using the above load, i.e., acceleration time history. The vibration response can also obtain a main frequency through power spectrum analysis. The load excitation and vibration response can be compared from the perspectives of time history and frequency.
