Document Type: Proceeding Paper

Part of: Computing in Civil and Building Engineering


The Bridge Branch of the Colorado Department of Transportation (CDOT) has organized the framework of a formal decision process for retaining wall selection. The process facilitates implementation of new technologies by encouraging Bridge Branch designers and consultants to consider a range of options when selecting retaining wall alternatives. Following the CDOT framework, this paper describes the computerized implementation of a knowledge-based system for eliminating infeasible walls based on constructability evaluation and a comparison of alternative methods for scoring and ranking feasible wall types.
