The invention discloses an optimization calculation method for mountainous area road earthwork volume. The method comprises the following steps: acquiring road elevation data, establishing a road initial terrain curved surface, generating an initial roadbed cross section diagram, acquiring construction area elevation data after road construction, replacing the elevation data of the initial terraincurved surface, and establishing a constructed terrain curved surface; replacing the initial topographic curved surface with a constructed topographic curved surface to generate a constructed roadbedcross section diagram; forming a roadbed cross section comparison diagram according to the same pile number, performing earthwork amount calculation according to different pile intervals, fitting according to the relation between the pile intervals and excavation and fill errors and a linear function, and obtaining the maximum linear pile interval, meeting the maximum error requirement, of the excavation and fill amount; calculating the cross section area of the road earthwork and the excavation area of the excavation and fill retaining wall; and calculating the excavated earth volume according to the area and the distance, and adding the excavated volume of the excavated and filled retaining wall to obtain the excavated and filled earth volume of the mountainous road. The method improvesthe scientificity and accuracy of calculation.
Description
technical field [0001] The invention relates to the technical field of road engineering, in particular to an optimal calculation method for earthwork volume of roads in mountainous areas. Background technique [0002] Due to the large ups and downs of the roads in mountainous areas, a large amount of excavation and filling will be generated during road construction, especially for high slope sections, the amount of excavation and filling will be even greater. The earthwork volume of mountainous roads is an important part of the investment and settlement of road engineering construction. Accurately calculating the earthwork volume of mountainous roads is of great significance to the budget in the early stage of the project and the settlement in the later stage. However, the calculation method of excavation and filling volume, the reasonable calculation range of excavation and filling volume, and the calculation accuracy have a great influence on the accuracy of the calculatio...
