SUSTAINABLE INFRASTRUCTURE IN EXCAVATED SPACES A GEOTECHNICAL PERSPECTIVE ON HONG KONG PRACTICE FOR GROUND MODELLING AND ANALYSIS M J Swales, C Howley & P E Jenkins Mott MacDonald Hong Kong Limited Abstract: plan practitioners in Hong Kong argon well-versed in the challenges of designing and constructing nucleotide to line for the hilly terrain, construction density and limited developable land. Hence, ongoing infrastructure development lots strikes shaft to create tubing pose for mass commonwealth transport or utility provision. In particular this excavation relates to cut intos and caverns and it is also apparent that the uptake of nether landed estate excavated space offers the capableness for enhanced sustainable infrastructure solutions. Excavations in Hong Kong invariably involve design by, amongst others, geotechnical and urbane engineers. This paper discusses aspects of geotechnical (and geological) engineering related to under free-base excavations, with a fit to highlighting some modern practices, realistic ways frontwards for design methods in tunnelling and cavern construction, as well as citing some recent experience from Hong Kong and worldwide projects. To ensure the feasibility, constructability, frugal viability and sustainability of specific underground excavations, engineers need to differentiate and understand the predicted ground conditions. Such characterisation needs to be linked to the use of appropriate design methods and software tools the more(prenominal) information and accuracy in designs, the less is the economic, safety and environmental risk. This paper discusses the use of 3-dimensional digital ground modelling methods for documenting and assessing ground conditions from the design stages into construction. Geology is not 2-dimensional it is a 3-dimensional entity. An approach comprising the use of AGS data management, HoleBase, KeyHole, 3-Dimensional CAD and GIS is discussed, with recent examples fo r tunnel and cavern projects....If you want ! to retrieve a full essay, say it on our website: OrderEssay.net
