内河护岸工程的能耗定量评价

为指导护岸工程节能及形式选择,从护岸工程建设期全生命周期角度将总能耗定义为由生产阶段的材料能耗、运输阶段及施工阶段能耗组成,给出了各部分能耗分析的数学统计模型,并针对常州市区段航道改线项目中的4种主要护岸类型分别进行了对比分析。结果表明:护岸的形式对工程的能耗影响较大,以重力式混凝土灌砌块石护岸每延米耗能情况做为基准,衡重式护岸是其84.2%,悬臂式护岸是其107.3%,悬臂式驳岸+(绿化)护坡的形式仅为其67.0%。

Quantitative assessment of the energy consumption for inland river bank protection

For guiding river bank protection energy-saving and type selection considering the whole life cycle of bank protection project, total energy consumptions are composed of the material energy consumption in production stage, transport stage and construction stage. The mathematical statistical models for energy consumption analyses of each part are given in this paper, comparative analysis on four different kinds of bank protection in Changzhou urban waterway realignment project is conducted as well. The result shows that project energy consumption is significantly affected by the form of bank protection. By comparing with the energy consumption of concrete gravity grouting bank protection per meter, the consumption of balance weight type bank protection is 84.2% of that with 107.3% of that for cantilever type and 67.0% of that for cantilever revetment with greening revetment.
