A systematic approach is proposed for civil engineers in the Middle East to minimise the impact of their infrastructure projects on climate change. Based on value engineering principles and a carbon dioxide emissions calculator, the approach was applied to three case studies: temporary retaining walls for a deep tunnel; reuse of site-won material from an open-cut tunnel; and design of piled raft foundations. The results showed the approach was effective in reducing carbon dioxide emissions and could be beneficially adopted on future earthworks projects in the Middle East.

如何减少中东基础设施项目的二氧化碳排放

为中东的土木工程师提出了一种系统方法，以尽量减少其基础设施项目对气候变化的影响。基于价值工程原理和二氧化碳排放计算器，该方法应用于三个案例研究：深隧道临时挡土墙；从露天隧道中回收的现场材料的再利用；和桩筏基础的设计。结果表明，该方法可有效减少二氧化碳排放，并可有益地用于中东未来的土方工程项目。
