摘要
针对堆石坝土石方调配过程中易产生的料场水土流失、污染、多余占地等环境问题,结合绿色施工,引入料场水土防治费用模型,将水土防治费用与调配费用一起纳入绿色调配费用。从提高直接上坝率、减少中转与弃渣、物尽其用的角度出发,构建绿色调配费用最低的多目标绿色土石方调配模型。工程应用表明,本模型优化方案可提高开挖料的直接上坝量,减少弃渣和开采,减少料场占地面积,降低了土石方调配对生态环境的破坏和影响,实现了土石方调配的绿色性,可为绿色土石方调配方案决策提供参考。
As a key link of rock-fill dam construction ,it is easy for earth rock allocation to produce the ecological environment prob‐lem .In the light of problems in environment field soil erosion ,pollution ,excess covering such material blending process ,cost model of material field to prevent soil and water is brought into the green deployment costs combined with the green construction including the soil and water control cost and allocation cost .From the viewpoints of improving the rate of direct on the dam ,reducing transit and waste slag ,turning material resources to good account ,multi-goal of green earth rock allocation models with the lowest cost of green deployment is concluded .The engineering application shows that ,this model can improve the directly dam volume of the exca‐vated material and reduce spoil and mining ,and the covered area of material field ,and reduce earthwork mixing the destruction of the ecological environment and influence ,realize the green of earth rock allocation ,which can serve as a reference for green earth rock al‐location scheme decision .
