Advances in Shallow Seismic Investigation for Managing Ground Risk

Complementing traditional approaches to site characterisation, recent developments in near-surface seismic investigation techniques have led to better representation of ground structure and in-situ geotechnical properties, improving the likelihood of avoiding unforeseen ground conditions for infrastructure development. The civil engineering sector has sometimes had a somewhat jaundiced view of geophysics, but a properly designed, executed and communicated (and critically, early) geophysical screening strategy can help not only to optimise subsequent intrusive campaigns but to populate what can represent large information gaps (uncertainty) in the Ground Model space between points of control such as boreholes and probings and their associated localised tests. For existing and future infrastructure developments, looking ahead, the evolution of legislation relating to seismic site assessment and site vulnerability for dense urban areas such as Hong Kong necessitates an awareness of the art of the possible for geophysical investigation. We review six seismic methods where recent advances in data acquisition technology and/or processing offers an opportunity for improved early screening for infrastructure development and / or seismic site assessment, and benefits in terms of better risk evaluation and timely decision-making.

Technical Visit to the Netherlands - Study of Global Practices on Land Reclamation, Coastal Resilience and Spatial Urban Design

The HKIE Geotechnical Division is organising a technical visit to the Netherlands between 25 and 31 August 2019. The visit is aimed at enriching Hong Kong engineers’ knowledge on global practices on land reclamation, including coastal flood protection and ecosystem restoration, as well as spatial planning concepts in urban design including smart use of underground space. To meet the challenges faced by Hong Kong, it is a right timing for us to tap into other countries’ experience and expertise. The Netherlands is definitely a role model for us to learn, in particular regarding the strategy and approaches adopted in land reclamation, coastal resilience and city development.

Technical Visit to Contract No. NE/2016/05 - Development of Anderson Road Quarry Site - Pedestrian Connectivity Facilities Works Phase 2A

The works mainly include a) road improvement works at junction of Clear Water Bay Road and On Sau Road, and at New Clear Water Bay Road near Shun Lee Tsuen Road, b) construction a vehicular flyover from Lin Tak Road to Sau Mau ping road and provision of laybys at Lin Tak Road, c) construction of pedestrian connectivity facilities, including footbridges, lift towers and escalators in Kwun Tong district, d) provision of a public toilet for the proposed bus-to-bus interchange at Tseung Kwan O Tunnel Toll Plaza, and e) associated noise barriers and enclosures, slope works and landscaping works.

In this visit, participants will gather at the site and a presentation on the works and challenges of the project will be given, followed by a site visit.

Fundamentals of Rock Mechanics and Rock Engineering

This workshop covers some fundamental aspects and latest development of rock mechanics, rock engineering and engineering geology. It focuses on some common laboratory tests for the determination of the mechanical and physical parameters of rock material and rock masses. Some key issues are illustrated in the rock slope stability assessment. 1:30pm-2:20pm - Rock testing, characterization and monitoring, implementation problems and contractual issues in practice and future trends: Highlighting the ISRM suggested methods (Speaker: Resat Ulusay) 2:30pm-3:20pm - Shear strength of discontinuities – myths and tricks (Speaker: Louis Wong) 3:30pm-5:30pm - Harmonization of engineering geology and rock mechanics for rock slope stability assessment in engineering practice (Speaker: Resat Ulusay)
