Delivery of Design, Environmental Statement, Engineering, Construction Management of the UK's New High Speed Railway for the 21st Century

摘要

High Speed Two (HS2) is a new $67billion (56 billion pounds) high speed railway which will form a "spine" of a reshaped rail network providing an engine for growth and connecting eight out of the top ten regions within Great Britain. There are about 64km of twin bore and 8km of twin cell cut-and-cover tunnels. Principles of Systems Engineering (International Council on Systems Engineering (INCOSE)) have been incorporated to drive processes and approaches to underground structure design & construction. In addition, HS2 Ltd established an efficiency challenge programme specifically tasked with generating savings for the project through updating and refining existing standards/ guidance documents in geotechnical engineering and underground construction. This paper describes aspects of the design, engineering & construction management and environmental aspects to ensure high quality and cost effective underground structures for this innovative high speed railway including HS2s approach to tunnel porous portal designs for the various HS2 underground structures.
