内河限制性航道护岸全生命周期能耗计算方法

为指导内河护岸工程节能及形式选择，建立了护岸工程全生命周期各个阶段的能耗计算模型，护岸工程的总能耗由结构物能耗、运输及施工能耗、维修和拆除能耗组成。以盐河CL型护岸为实例进行计算，结果表明：所建立的内河限制性航道护岸全生命周期能耗模型能够很好地评价护岸各阶段的耗能情况，且结构物能耗占比最大，拆除能耗占比也较大，护岸工程节能应做好结构物选型，延长护岸的寿命，避免护岸拆除。

The LCA Energy Consumption Calculation for Inland Restrictive River Bank Protection

In order to help saving energy and choosing formation for riverbank protection works, this paper build a model that could compete the riverbank protection energy consumption at all stages of the whole life cycle. In this model, the total energy consumption consisted of the material consumption in design phase, the ordinary consumption in transportation, construction, maintenance and demolition phase. Then, the CL revetment along the river was taken as an example to prove the model. As a result, this inland waterways restrictive revetment lifecycle energy consumption model performed excellent to evaluate the energy consumption of revetment at all stages. In particular, most energy was consumed by the structure and the demolition also caused big energy consumption. Therefore, revetment selection of energy-saving structures should be well prepared to extend the life of revetment and avoid demolition.
