摘要
为准确测算13个工程类别、8个海拔区间共104个公路工程高原地区施工增加费率，采用相关分析与回归分析法对高原地区施工增加费率值与海拔高度关系进行定量分析；采用技术测定法实测特定海拔高度典型细目工程的高原地区施工增加费率；根据高原地区施工增加费率与海拔高度之间的定量关系，建立了由实测值推算相邻海拔区间高原施工增加费率的推算公式。依托实体工程以机械石方这一工程类别为例，分别对海拔高度为3001～3500m和3501～4000m的实测高原地区施工增加费率值与理论推算值、2007版规范值对比。研究结果表明：高原地区施工增加费率与海拔高度之间存在显著的二次多项式关系；高原地区施工增加费率的推算值与实测值之间的误差是合理的；建立的高原地区施工增加费率计算公式和推算公式具有一定的实用价值；高原地区特殊的施工环境对人工和机械的工效有显著影响，需进一步提高高原地区施工增加费率值。所得结论对合理确定和有效控制高原地区公路工程造价具有一定的借鉴意义。
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 stonework engineering category on the elevation height of 3 001-3 500 m and 3 501-4 000 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 plateaue 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. 5 tabs, 5 flus, 25 refs.
