Effective earth volume calculation method for poor foundation road

Abstract

The invention discloses an effective earth volume calculation method for a poor foundation road, and the method comprises the steps of collecting a road position and survey data, obtaining terrain elevation data, building a road original terrain curved surface and a road design model, and generating an initial roadbed cross section diagram; obtaining elevation data of a construction area after road construction; replacing the original terrain curved surface elevation data with the constructed elevation data; establishing a topographic curved surface to be trimmed; replacing an original terraincurved surface in the road design model, generating a repaired and measured roadbed cross section diagram, generating a roadbed cross section comparison diagram according to the same pile number, calculating an effective excavation and filling earthwork area between an original terrain ground line and a repaired and measured terrain ground line, and calculating an earthwork desilting area and a rubble landfill area according to marks of unfavorable geology; according to the cross section area and the length of the adjacent cross sections, calculating the effective soil excavation and fillingquantity and the unfavorable geology desilting and landfilling engineering quantity. According to the method, the scientificity and reasonability of road earth volume calculation are improved, and aneffective and reliable basis is provided for budget and settlement.

Description

technical field [0001] The invention relates to the technical field of road engineering, in particular to a method for calculating effective earthwork volume of roads with bad foundations. Background technique [0002] There are many ways to calculate or determine the earthwork volume of roads, but most of the factors considered in the calculation process of earthwork volume are relatively single, which leads to large errors in the calculation results and is difficult to popularize and use. For example, two commonly used ways to determine the earthwork volume in road engineering are: 1) the earthwork volume determined according to the survey data and technical parameter settings during the design process of road engineering; 2) the actual earthwork volume generated during the construction process. The designed earthwork volume is affected by multiple factors such as survey data, technical parameters, design software and designer experience, resulting in a large error between...

Problems solved by technology

The designed earthwork volume is affected by multiple factors such as survey data, technical parameters, design software and designer experience, resulting in a large error between the earthwork volume and the actual situation

However, the actual earthwork volume will be unbelievable due to overfilling and overexcavation during the construction process.

Moreover, the above two earthwork determination methods are cumbersome to operate, low in efficiency, and poor in accuracy, which seriously affects the budget and settlement of road projects
