Selection of driven piles for deep foundations is a complex process. Many subjective factors enter into the decision of which pile to select, making experience an important factor in proper selection. A short review of the problems associated with driven pile selection is presented. Because of the complexity of the problem and solution, an expert system solution, PILEX, is proposed. PILEX is a computer program founded on a knowledge base taken from the literature combined with current expert input. The system interactively interviews the non-expert user, who answers questions about the soil, driving and groundwater conditions. Based on the user's replies, the system suggests piles types that could be efficiently used at this site. The system is rapid, and simple to use. Expert systems are a new technology that hold great potential to change the way geotechnical engineering problems are solved. The introduction of PILEX as a practical pile selection tool is expected decrease construction costs by providing a rapid, consistent procedure for pile selection.
