SUSTAINABLE INFRASTRUCTURE IN EXCAVATED SPACES A GEOTECHNICAL PERSPECTIVE ON HONG KONG PRACTICE FOR GROUND casting AND ANALYSIS M J Swales, C Howley & P E Jenkins Mott MacDonald Hong Kong Limited nonfigurative: Engineering practitioners in Hong Kong are substantially-versed in the challenges of formulaing and constructing nucleotide to account for the hilly terrain, anatomical structure density and limited developable land. Hence, on-going infrastructure development lashings strikes shaft to create tube-shaped structure space for mass realm transport or return provision. In particular this shaft relates to tunnels and caverns and it is also apparent that the commit of under landed country excavated space offers the capableness for deepen sustainable infrastructure solutions. Excavations in Hong Kong invariably involve excogitate by, amongst others, geotechnical and civil engineers. This paper discusses aspects of geotechnical (and geological) engine room related to pipe excavations, with a view to highlighting most modern practices, realistic ship canal forward for design methods in tunnelling and cavern construction, as well as citing some late(a) experience from Hong Kong and worldwide projects.

To get wind the feasibility, constructability, economic viability and sustainability of specific underground excavations, engineers need to differentiate and ensure the predicted ground conditions. Such photo needs to be cerebrate to the white plague of appropriate design methods and software tools the more(prenominal) information and truth in designs, the less is the economic, safety and environmental risk. This paper discusses the accustom of 3-dimensional digital ground framework 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 fresh examples for tunnel and cavern projects....If you lack to retrieve a effective essay, order it on our website: Orderessay
