Abstract:This report focuses on improvement of design methodologies related to the ground-structure interaction in tunneling. The design methods range from simple analytical and empirical methods to sophisticated finite element techniques as well as an evaluation of tunneling practices in Austria and Germany. The purpose of this report is to provide the tunneling profession with improved practical tools in the technical or design area. These design tools provide more accurate representations of the ground-structure interaction in tunneling. The Executive Summary is the first of six publications to be published on the Improved Design of Tunnel Support. Volumes 1 through 5 will be published in March, 1980. This Executive Summary summarizes improvements in the methodology available to tunnel designers with the objective of reducing the cost of tunnel construction in the United States. This report summarizes each of the five volumes--Volume 1: Simplified Analysis for Ground-Structure Interaction; Volume 2: Aspects of Yielding in Ground-Structure Interaction; Volume 3: Finite Element Analysis of the Peachtree Center Station in Atlanta; Volume 4: Tunneling Practices in Austria and Germany; and Volume 5: Empirical Methods for Rock Tunneling--Review and Recommendations.
