Probabilistic analysis and design of reinforced soil walls and modelling of soil-reinforcement interaction using transparent granular soil

每个加拿大人都是土木工程基础设施安全和具有成本效益设计的利益相关者。该基础设施包括加筋土挡土墙结构，由于其与传统挡土墙技术相比具有成本效益，因此在加拿大景观中无处不在。然而，目前的设计方法不适合现代基于可靠性的设计，这种设计方法与结构工程师设计桥梁上部结构和建筑物的方法一致，已有30多年的历史。安大略省交通部（MTO）在最近的“基于岩土技术的可靠性设计”研究提案中表示：“如果岩土技术设计规范能够利用基于可靠性的概念，那么（在安大略省）每年可以轻松节省大约1000万美元的基础建设和设计成本。”现代加筋土挡土墙结构属于基础范畴。拟议研究的长期影响将是为所有加拿大人实现应用于这类结构的基于可靠性的设计概念的好处。

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.
