根据低碳经济中的碳排放研究成果,构建桩基工程的碳排放模型;以1000延米PHC桩为对象,列出材料与能源消耗清单,在此基础上估算新制桩基及既有桩基再利用的碳排放量,对比得出既有桩基再利用对生态环境所产生的积极影响,对类似的工程建设项目具有一定的参考价值。 Based on the research results of carbon emission in low-carbon economy, a carbon emission model for pile foundation engineering is constructed. A list of materials and energy consumption is put forward for 1,000-m PHC piles. On the basis of this, new-type pile foundation and existing pile foundation Reuse of carbon emissions, compared to the existing pile reuse of the positive impact on the ecological environment, for similar projects with a certain reference value.
