Through the steps, the map data are obtained to generate an original terrain, wherein the original terrain comprises a starting point and an end point of a section of road; marking a route of a road from a starting point to an end point on original terrain; acquiring height data of a route on original terrain, and generating a road diagram of the road, wherein the road diagram is a height change curve graph of the original terrain in the length direction of the road; determining tunnel and bridge parts of the road according to the circuit diagram; the method for determining the paving cost of the road according to the route, the tunnel and the bridge part of the road achieves the purposes of determining the height change curve of the road according to the three-dimensional model of the original terrain, determining the bridge and the tunnel part of the road according to the height curve and determining the paving cost of the road according to different parts, thereby achieving the technical effect of improving the efficiency of determining the paving cost of the road, and further solving the technical problems that the method for evaluating the cost of the road through manual calculation in the prior art cannot be considered comprehensively and the efficiency is low.
Above-mentioned original topography can be gathered through global positioning system, for example beidou positioning system, and it is high to have the precision, convenient to use's effect. The map data is also a map generated by the global positioning system according to the collected topographic data. The start point and the end point of the road are included in the original terrain so that the height of the road is analyzed. The road can be one road section in eleven whole roads, and analysis is convenient.
The route of a road from a starting point to an end point is marked on original terrain, and a design file of the road can be obtained firstly, wherein the design file of the road is provided by a designer and comprises a plurality of alternatives of the road or a specific circuit diagram of one scheme.
Specifically, a three-dimensional model of the original terrain; marking a route of a road from a start point to an end point on original terrain includes: acquiring a road design drawing, and selecting a starting point and an end point of a road section to be determined and longitude and latitude information of the road section according to the road design drawing; and generating a route track of the road section from the starting point to the ending point on the original terrain according to the longitude and latitude information of the road section.
From the map data of the original terrain and the route on the original terrain, a height profile of the road along the length of the road can be determined. The abscissa of the height curve variation graph is the road length, i.e., the distance from the road to the starting point or the ending point. The ordinate is the altitude of the original terrain of the road at that point.
Specifically, the step of obtaining height data of the route on the original terrain and generating the road map comprises the following steps: acquiring the altitude of a route on an original terrain, and carrying out statistics to generate a route map; according to the circuit diagram, the circuit diagram is provided,
from this map, and the associated road design criteria, the maximum slope of the road can be determined, beyond which the vehicle cannot travel and the road is not qualified. The need to tunnel or bridge is determined in conjunction with the original terrain by marking the portion that exceeds the maximum slope.
When tunnel and bridge portions of a road are determined: and smoothing the circuit diagram according to the preset height difference, and eliminating a burr curve in the circuit diagram, thereby eliminating the influence of uneven terrains on a judgment result and the judgment accuracy of a high bridge and tunnel part.

The laying cost of the tunnel and bridge part road is obviously different from that of the common road section. Therefore, considering the laying costs of tunnels and bridges, the ordinary laying costs of roads that gather other parts determine the final laying costs. Compared with a way of evaluating roads by artificial calculation, the method needs to artificially determine the actual road condition firstly, then calculates the cost according to the actual road, is easy to make mistakes, has lower efficiency, and is more efficient and accurate.
Optionally, marking, in the processed road map, a target road segment whose slope exceeds a preset slope threshold includes: when the slope is positive, marking a first target road segment with a slope exceeding a first slope threshold; when the slope is negative, marking a second target road section with the slope exceeding a second slope threshold value; wherein the first slope threshold is positive and the second slope threshold is negative. It should be noted that along the road direction, the slope is determined to be positive when the terrain is high and exceeds the preset slope threshold, and the slope is determined to be negative when the terrain is low and exceeds the preset slope threshold. In other embodiments, the positive and negative values of the slope may be opposite to those described above, and may be set according to the actual implementation requirements. The setting can effectively distinguish the bridge part from the tunnel part, and is convenient for subsequent distinguishing processing.
Determining the target road section as a tunnel part, a bridge part or a normal part according to the value of the slope of the target road section and the length of the target road section comprises: under the condition that the length of the first target road section reaches a first preset length, determining the first target road section as a tunnel part, and showing that the original terrain is not only high relative to road pavement, but also has a long distance of high height and is suitable for the tunnel part; under the condition that the length of the first target road section does not reach a first preset length, determining the first target road section as a first normal part, wherein the first normal part needs to excavate earthwork with a certain height to realize a road paving part, and the fact that the original terrain is higher than the road paving part but the distance is not long can be achieved through an open excavation mode, so that the road paving cost is saved, and the road open excavation cost is far less than the tunnel paving cost; under the condition that the length of the second target road section reaches a second preset length, determining the second target road section as a bridge part, and showing that the original terrain is not only low in height relative to road pavement, but also long in distance of the low height, and is suitable for erecting the bridge part; and under the condition that the length of the second target road section does not reach a second preset length, determining the second target road section as a second normal part, wherein the second normal part needs to be backfilled with earthwork with a certain height to realize a road paving part, and the fact that the original terrain is lower than the road paving part, but the distance is not long enough to realize backfilling of earthwork can be shown, so that the road paving cost is saved, and the cost for backfilling earthwork is far less than the bridge erection cost.
Optionally, determining the paving cost of the road according to the route of the road and the tunnel and bridge part comprises: determining the excavated earth volume of the tunnel according to the length of the tunnel part of the road and the tunnel end surface of the tunnel design scheme; determining the common excavation earth volume of the road according to the first normal part and other parts of the road which are normally paved; determining the excavation length of the bridge according to the bridge part of the road; determining the backfill earthwork amount of the road according to the second normal part; and determining the paving cost of the road according to the tunnel excavation earth volume, the common excavation earth volume, the bridge excavation length and the backfill earth volume.
The corresponding cost of different road sections is different, and the geological conditions of the original terrain can be specifically referred to, the road laying cost of the rock geology is lower than that of the sandy soil geology, but the excavation cost of the rock geology is higher than that of the sandy soil geology.
Optionally, determining the common excavated volume of earth of the road according to the first normal portion and the other portions of the road where the road is normally laid comprises: generating a road model on the original terrain according to the first normal part and other parts of the road normally laid; determining the common excavation earth volume of the first normal part and other parts of the road normally paved in a data modeling mode; determining the amount of backfill of the road according to the second normal segment comprises: generating a road model on the original terrain according to the second normal part; and determining the backfill earth amount of the second normal part by means of data modeling.
When determining the excavated earth volume or the backfill earth volume, the data modeling can be carried out through key data such as height, depth, length and the like, and the approximate earth volume can be estimated, so that the laying cost corresponding to different road sections can be determined. In the road section where the earth is to be backfilled or the excavated earth is to be captured, not only the amount of the earth to be backfilled or the excavated earth but also the cost for laying the road need to be considered.
Optionally, determining the paving cost of the road according to the tunnel excavation earthwork amount, the common excavation earthwork amount, the bridge excavation length and the backfill earthwork amount comprises: according to first unit costs corresponding to tunnel excavation earth volume, common excavation earth volume, bridge excavation length and backfill earth volume, respectively determining laying costs corresponding to tunnel excavation earth volume, common excavation earth volume, bridge excavation length and backfill earth volume; and determining the total paving cost of the road according to the paving costs respectively corresponding to the tunnel excavation earth volume, the common excavation earth volume, the bridge excavation length and the backfill earth volume.
The excavated earthwork can be applied to a road section needing earthwork backfilling so as to save cost, and the total excavated earthwork amount can be determined according to the excavated earthwork amount of the tunnel and the ordinary excavated earthwork amount; and under the condition that the total excavated earthwork is smaller than the backfill earthwork, the excavated earthwork is insufficient to meet all road sections with backfill requirements, but all excavated earthwork can be used up, so that the processing cost of excavated earthwork can be saved, calculating the tunnel excavated earthwork, the common excavated earthwork and the laying cost of partial backfill earthwork by using a second unit cost, and determining the tunnel excavated earthwork, the common excavated earthwork and the laying cost of partial backfill earthwork, wherein the second unit cost is smaller than the corresponding first unit cost. The amount of the partial backfill earthwork is equal to the total excavation earthwork, and the source of the backfill earthwork does not need to be considered, so that the cost can be saved to a certain extent.
Under the condition that the total excavated earth volume is larger than the backfill earth volume, the requirement of the backfill earth section is indicated to be insufficient for supporting the total excavated earth volume, the rest excavated earth volume needs to be processed, but the earth sources of the backfill earth volume are completely different, the backfill earth volume is calculated according to a third unit cost, namely the cost without the earth sources, and the backfill earth volume, the laying cost of the partial tunnel excavated earth volume and the common excavated earth volume are determined, wherein the third unit cost is smaller than the corresponding first unit cost. The excavation earth volume of the partial tunnel and the ordinary excavation earth volume are equivalent to the backfill earth volume, the excavation earth processing is not needed to be considered, and the cost can be saved to a certain degree.
