Every Canadian is a stakeholder in the safe and cost-effective design of civil engineering infrastructure. Included in this infrastructure are reinforced soil retaining wall structures which are ubiquitous on the Canadian landscape due to their cost-effectiveness compared to traditional retaining wall technologies. However, current design methods are not suited for modern reliability-based design consistent with the approach that has been used by structural engineers to design bridge superstructures and buildings for more than three decades. The Ministry of Transportation of Ontario (MTO) stated in a recent call for research proposals for "Geotechnical-based Reliability Design" that: "If geotechnical design codes were to take advantage of reliability-based concepts, an overall savings in foundation construction and design costs of roughly $10 million per year could easily be achieved [in Ontario]." Modern reinforced soil retaining wall structures fall within the foundation category. The long-term impact of the proposed research will be to realize the benefit of reliability-based design concepts applied to this class of structure for all Canadians.

每个加拿大人都是土木工程基础设施安全和成本效益设计的利益攸关方。包括在这个基础设施是加筋土挡土墙结构，这是无处不在的加拿大景观，由于其成本效益相比，传统的挡土墙技术。然而，目前的设计方法不适合现代的基于可靠性的设计方法，已被结构工程师用来设计桥梁上部结构和建筑物超过三十年。安大略交通部（MTO）在最近的一次“基于岩土工程的可靠性设计”研究提案征集中指出：“如果岩土工程设计规范利用基于可靠性的概念，[在安大略]每年可轻松实现大约1000万美元的基础建设和设计成本的总体节省。“现代加筋土挡土墙结构属于基础类别。拟议研究的长期影响将是实现基于可靠性的设计概念适用于这类结构的所有加拿大人的好处。
