Reliability of pile axial capacity in glacial tills

点击翻译按钮获取中文摘要

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.
