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设计设计的利益相关者。在此基础设施中包括加固的土壤固定壁结构，与传统的固定壁技术相比，由于其成本效益，在加拿大景观上无处不在。但是，当前的设计方法不适合基于现代可靠性的设计，该设计与结构工程师使用的方法相一致，用于设计桥梁的上层建筑和建筑物已有三十多年了。安大略省（MTO）运输部在最近提出的“基于岩土的可靠性设计”的研究建议中指出：“如果岩土技术设计代码是利用基于可靠性的概念的优势，那么在Ontario中可以轻松实现基础建设和设计成本的总体节省，每年可以轻松实现1000万美元。”现代增强的土壤固定壁结构属于基础类别。拟议研究的长期影响是实现适用于所有加拿大人的基于可靠性的设计概念的好处。
