For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0087] like Figure 1 As shown, a method for online monitoring of road pavement settlement according to a preferred embodiment of the present application includes:

[0088] S101: Obtaining road surface parameters according to preset feedback time nodes and generating a road surface monitoring model;

[0089] S102: establishing a plurality of monitoring sub-areas according to the road surface monitoring model, and generating the settlement amount of each monitoring sub-area according to a preset static load model and a dynamic load model;

[0090] S103: Generate a settlement evaluation value for each monitoring sub-area according to a preset correlation model, and determine whether to generate an early warning instruction.

[0091] Specifically, the road surface parameters include:

[0092] Pavement shape, pavement texture and pavement color.

[0093] Specifically, the road surface information, including the shape, texture, and color of the road surface, is obtained by scanning the road surface with a laser scanner, and then entered into the chromatographic analysis platform and converted into a digital image for chromatographic analysis. Relevant information about the road surface settlement condition is obtained by extracting specific color, shape, and other parameters from the image. The chromatographic analysis results are used as input data to establish a road surface model and multiple monitoring sub-areas.

[0094] Specifically, when generating the settlement amount of each monitoring sub-area, it includes:

[0095] Establish a monitoring sub-area sequence A, A = (a1, a2...an), where ai is the i-th monitoring sub-area; n is the number of monitoring sub-areas;

[0096] Set multiple static monitoring areas according to the static load model;

[0097]

[0098] f1 = α / β; f2 = α / θ;

[0099] Wherein, K is a static monitoring area division parameter; R is auxiliary data; cos f1 and sin f2 are road surface slope values; n is the number of monitoring sub-areas;

[0100] Generate static settlement parameters for each static monitoring area;

[0101] Set multiple dynamic monitoring areas according to the dynamic load model;

[0102]

[0103] f1 = α / β; f2 = α / θ;

[0104] Generate dynamic settlement parameters for each dynamic monitoring area;

[0105] Obtain all static settlement parameters and all dynamic settlement parameters, perform weighted processing, and generate the settlement amount of each monitoring sub-area according to the processing result;

[0106] Establish a settlement amount sequence B at the current feedback time node, B = (b1, b2... bn), where bi is the settlement amount of the i-th monitoring sub-area at the current feedback time node.

[0107] Specifically, according to vehicle load, nearby buildings, soil properties, environmental humidity and road surface structure characteristics. Through the superposition factor data, perform enhanced calculation processing to generate the weight values of static settlement parameters and dynamic settlement parameters. Through weighted processing, reduce the monitoring error, improve the monitoring accuracy of the highway road surface settlement state and the calculation accuracy of the settlement amount of each monitoring sub-area.

[0108] In the preferred embodiment of the present application, when generating the settlement evaluation value of each monitoring sub-area according to the preset correlation model, it includes:

[0109] Set ai as the target monitoring sub-area in sequence according to the monitoring sub-area sequence A;

[0110] Generate the correlation degree evaluation value between the target monitoring sub-area and each monitoring sub-area according to the preset correlation model;

[0111] Establish a correlation degree evaluation value sequence D, D = (d1, d2... dn), where di is the correlation degree evaluation value between the i-th monitoring sub-area and the target monitoring sub-area;

[0112] Preset the first correlation degree evaluation value threshold D1;

[0113] If di < D1, set the i-th monitoring sub-area as the first-level associated sub-area of the target monitoring sub-area;

[0114] Obtain the settlement amounts of all first-level associated sub-areas;

[0115] Generate the settlement evaluation value h of the target monitoring sub-area at the current feedback time node;

[0116] When generating the settlement evaluation value h, it includes:

[0117] h=G*[e1*Q1*b+e2*Q2*(v-Δv)+e2*Q2*(b-Δb)];

[0118] Among them, e1 is the preset first weight coefficient; e2 is the preset second weight coefficient; e3 is the preset third weight coefficient; Q1 is the preset first fixed coefficient; Q2 is the preset second fixed coefficient; Q3 is the preset third fixed coefficient; b is the settlement amount of the target monitoring sub-area at the current feedback time node; v is the settlement rate of the target monitoring sub-area at the current feedback time node; Δb is the average settlement amount of all first-level associated sub-areas of the target monitoring sub-area; Δv is the average settlement rate of all first-level associated sub-areas of the target monitoring sub-area; G is the compensation coefficient set based on historical settlement parameters.

[0119] Generate the settlement evaluation value of each monitoring sub-area at the current feedback time node in turn.

[0120] Specifically, similarity processing is performed based on the load parameters of each monitoring sub-area between the current feedback time node and the previous feedback time node, the pavement parameters between different monitoring sub-areas, the soil structure and other parameters. The higher the similarity, the higher the correlation evaluation value between the two monitoring sub-areas.

[0121] Specifically, the greater the difference between the settlement parameters of the target monitoring sub-area and the settlement parameters of the corresponding first-level associated sub-area, the higher the possibility that an abnormality exists in the target monitoring sub-area.

[0122] Specifically, each evaluation index is normalized according to the preset first fixed coefficient, the second fixed coefficient and the third fixed coefficient, so that each evaluation index is within the same value range.

[0123] Specifically, when determining whether to generate an early warning instruction, it includes:

[0124] Establish a sedimentation evaluation value sequence H at the current feedback time node, H = (h1, h2…hn), where hi is the sedimentation evaluation value of the i-th monitoring sub-area at the current feedback time node;

[0125] Preset the settlement evaluation value threshold H1;

[0126] If hi>H1, the i-th monitoring sub-area generates a warning instruction at the current feedback time node;

[0127] If hi

[0128] Specifically, the larger the settlement evaluation value, the greater the possibility that the settlement state of the corresponding monitoring sub-area is abnormal. When the settlement evaluation value exceeds the settlement evaluation value threshold, it means that there is a settlement risk in the corresponding monitoring sub-area, and timely maintenance is required to avoid driving problems and ensure the safety of the road surface.

[0129] It can be understood that in the above embodiment, by establishing multiple monitoring sub-areas, the settlement state of the highway pavement is comprehensively monitored, and by constructing a correlation model, the settlement state of each monitoring sub-area is compared and analyzed, and the settlement amount is dynamically corrected in combination with historical parameters, thereby improving the prediction accuracy of the settlement risk of each monitoring sub-area and ensuring the safety of the road surface.
