本指南概述了加拿大北部多年冻土地基上工程结构在使用寿命期间的可持续性评估方法。目标是在设计阶段减轻气候变化导致的系统故障风险。其目的是适应整个加拿大北部预期的气候变化影响。本指南最初于2010年为社区决策者制定，以便在新社区基础设施的选址、设计和管理过程中考虑气候变化对永久冻土的影响。该更新版本更具通用性，适用于永久冻土地区的所有新基础设施，包括用于资源开发的基础设施。 该指南将帮助在永久冻土上修建新基础设施的工程设计。

This Guideline outlines methods to estimate the sustainability of engineered structures on permafrost foundations over their service lives in northern Canada. The objective is to mitigate climate-change- induced risk of system failure at the design stage. The intent is to accommodate climate change effects anticipated throughout the Canadian North. This Guideline was developed initially in 2010 for community decision makers so that the impacts of climate change on permafrost are considered during the siting, design, and management of new community infrastructure. This updated version is more general and is applicable to all new infrastructure in permafrost regions, including those for resource development. The guideline will assist engineering design of new infrastructure to be built on permafrost.
