- Abstract:
- In order to accurately calculate the construction increase rate of 104 highway engineering in plateau areas composed from 13 project categories and 8 altitude ranges, correlation analysis method and regression analysis method were used to quantitatively analyze the relationship between construction increase rate and altitude. Construction increase rate of the typical engineering items at a certain altitude were measured by technical method on construction field. The calculating formulas of construction increase rates of plateau areas for the adjacent altitude were built by the measured value according to the quantitative relationship between construction increase rate and altitude. The contrast was made among the standard value in 2007 edition, the measured value, the theoretical calculation value for construction increase rate which were based on mechanical stone work engineering category on the elevation height of 3001-3500 m and 3501-4000 m. The results show that there is a significant quadratic polynomial relationship between construction increase rate of plateau areas and altitude. The error between the calculation value and the measured value for construction increase rate of plateau areas is reasonable. The built computational formulas and the calculating formulas have certain practical value. The efficiency of the labors and equipments is significantly affected by construction environment in plateau areas and construction rates should be increased. The conclusion has certain references for reasonably determining and effectively controlling highway engineering cost.
