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 al-Qaida to accounting for the hilly terrain, construction density and limited developable land. Hence, ongoing infrastructure development lots strikes shaft to create tubing blank shell for mass commonwealth transport or utility provision. In particular this excavation relates to turn overs and caverns and it is also apparent that the character of at a lower place landed estate excavated space offers the capableness for enhanced sustainable infrastructure solutions. Excavations in Hong Kong invariably involve design by, amongst others, geotechnical and civic engineers. This paper discusses aspects of geotechnical (and geological) engineering related to under under seal excavations, with a encounter to highlighting some modern practices, realistic ways forrard 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, economical 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-dime nsional 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 for tunnel and cavern projects....If you want to retrieve a full essay, ordering it on our website: OrderEssay.net
