Price: Only $650 / Attendee
The enhanced performance-based design of foundation systems remains a critical challenge in geotechnical engineering. Deep foundations are essential substructure systems for mega-projects, heavy structures, tall buildings, and onshore/offshore facilities, particularly in irregular environments and challenging subsurface conditions. Despite extensive experience and research in piling, persistent simplifications, conservatism, and uncertainties continue to hinder optimal design. Among various approaches for geotechnical design, the Cone Penetration Test (CPT) and PiezoCone (CPTu) have been witnessed as versatile tools, providing rapid, continuous, and high- resolution records.
The CPT application, as a model pile, significantly enhances the reliability of design and performance by offering detailed insights into soil-pile interactions. It aims to identify challenging site conditions through SBC, installation technology, and the appropriate selection of piling patterns and embedment depths. Key design concerns will be addressed, including bearing capacity, settlement, resistance distribution, and load-displacement trends.
Besides, this workshop examines the application of CPT/CPTu for predicting axial capacity through both direct and indirect methods. Established and emerging methodologies are critically reviewed, supported by case studies demonstrating their utility across diverse pile types and subsurface conditions. Ultimately, integrating geotechnical, constructional, and structural disciplines through the
appraisal of load-displacement behavior advances to the optimal pile design
