Abstract

A European Commission (EC) funded Sustainable Construction of Underground Infrastructure (SCOUT) project introduces a breakthrough for the construction of “cut-and-cover” tunnel using a horizontal diaphragm walling equipment with the implementation of the Observational Method for the construction of the underground structure. Design optimisation options such as the use of different structural forms, new construction material and even the design approaches were explored in an attempt to provide a sustainable design for the underground structure. This paper will briefly describe the project background, design optimisation approach and present back analyses undertaken of retaining wall case histories to develop a methodology to derive design parameters appropriate for the implementation of the Observation Method under the framework of Eurocodes.

Case Histories Back Analyses for the Application of the Observational Method under Eurocodes for the Scout Project

Arlington, Virginia

A European Commission (EC) funded Sustainable Construction of Underground Infrastructure (SCOUT) project introduces a breakthrough for the construction of “cut-and-cover” tunnel using a horizontal diaphragm walling equipment with the implementation of the Observational Method for the construction of the underground structure. Design optimisation options such as the use of different structural forms, new construction material and even the design approaches were explored in an attempt to provide a sustainable design for the underground structure. This paper will briefly describe the project background, design optimisation approach and present back analyses undertaken of retaining wall case histories to develop a methodology to derive design parameters appropriate for the implementation of the Observation Method under the framework of Eurocodes.
