我们比较了温室气体（GHG）的排放量从日志桩（LP），从砂压实桩（SCP）和水泥深层搅拌（CDM）的措施，对土壤液化，假设森林和废物管理的情况下，影响温室气体（CO2，CH4和N2O）平衡的木材。我们发现LP和SCP方法在化石燃料和石灰石消耗的GHG排放方面几乎没有区别。然而，清洁发展机制方法的温室气体排放量比LP方法的排放量高7倍。在木材的温室气体平衡中，当地下木材中碳的CH4排放百分比低于3.3%时，永久储存在原木中比使用废弃原木作为燃料代替煤或重油实现了更大的温室气体排放减少。为了通过用有限方案取代SCP或CDM来减少温室气体排放量，必须进行可持续森林管理，包括重新造林和防止地下原木的CH4排放。通过重新造林、原木永久储存、原木无CH4排放、使用采伐剩余物代替煤炭，LP可以通过替代CDM实现每100 m2改善面积减少121吨CO2的温室气体排放。
We compared the greenhouse gas (GHG) emissions from a log pile (LP) to those from a sand compaction pile (SCP) and from cement deep mixing (CDM) as measures against soil liquefaction, assuming that forest and waste management scenarios influence the GHG (CO2, CH4, and N2O) balance of wood. We found little difference between the LP and SCP methods with respect to GHG emissions from fossil fuel and limestone consumption. However, GHG emissions from the CDM method were seven times higher than emissions from the LP method. In the GHG balance of wood, when the percentage of CH4emissions from carbon in underground wood was lower than 3.3%, permanent storage in the log achieved greater reductions in GHG emissions than using the waste log as fuel in place of coal or heavy oil. In order to obtain reductions in GHG emissions by replacing SCPs or CDM with LPs, sustainable forest management with reforestation and prevention of CH4emissions from the underground log are essential. Using reforestation, permanent storage of the log, no CH4emission from the log, and using logging residues instead of coal, the LP can achieve reductions in GHG emissions of 121 tonnes of CO2per 100 m2of improvement area by replacing CDM.
