The design of high performance anchored retaining walls within the Eurocode framework

摘要

The design of high performance anchored retaining walls is a complex process that must embrace the elements of efficient design, analysis, execution and validation. The performance of such structures is governed by complex soil-structure interaction phenomena and to derive a satisfactory composite structure the design of the individual elements must be optimised. In this paper the term 'high performance' is defined as a structure where each element's performance is optimised to give a safe and economic solution. The suite of European Standards (the Eurocodes and Euronorms) seek to provide a comprehensive design, execution and testing framework for all civil engineering structures, however a daunting array of documents must be consulted when designing specific structures such as anchored retaining walls. It is therefore helpful to summarise the pertinent elements affecting the design, execution and validation of high performance anchored retaining walls in one document and this paper seeks to do this. The suggest framework for designing high performance anchored retaining walls has been developed from the authors' experience working as practioners within industry and as participants on a number of standards committees including CEN TC288 Execution of Special Geotechnical Work, TC288/WG14 Execution of Special Geotechnical Works - Ground Anchors, TC250/SC7/EG1 Ground Anchors, BSI/B526 Geotechnics, TC341 Anchor Testing and B/526/-/3 - Anchors; BSI's UK Ground Anchors Panel. The paper illustrates the elements of design, execution and testing of high performance anchored retaining walls using the Eurocode suite of standards with the use of a practical example.
