This proposed research is to conduct a statistical analysis of field load test data of pile foundation in glacial tills and establish a reliability-based design method. Pile foundations are frequently used to support new structures or upgrade existing infrastructure throughout Canada. Due to many uncertainties involved, a simplified design is normally implemented in practice. In addition, as glacial deposits throughout the GTA exhibit highly variable material properties, the evaluation and interpretation of their properties is a subjective process and can easily lead to inconsistent designs. This research will address this issue by collecting pile load test data in glacial tills to conduct a statistical analysis of pile axial capacity in glacial tills in Ontario. The ultimate goal of this research is to establish a reliability-based design method for piles to help support cost-effective infrastructure developments in Ontario. This project will crucially involve the training of highly qualified personnel to solve real engineering problems.

本研究目的在于统计分析冰碛物中桩基的现场载荷试验数据，建立基于可靠度的设计方法。桩基础经常用于支撑加拿大各地的新结构或升级现有基础设施。由于涉及许多不确定性，在实践中通常采用简化设计。此外，由于整个大多伦多地区的冰川沉积物具有高度可变的材料特性，对其特性的评估和解释是一个主观的过程，很容易导致设计不一致。本研究将通过收集冰碛物中的桩载荷试验数据来解决这个问题，以对安大略冰碛物中的桩轴向承载力进行统计分析。本研究的最终目的是建立一种基于可靠度的桩基设计方法，以帮助支护经济有效 安大略的基础设施建设。这个项目将至关重要地涉及高素质人才的培训，以解决真实的工程问题。
