Abstract
Concepts and solutions for new generation of land reclamation
Land reclamation has been a major construction activity in Singapore and several other countries inAsia. However, there are challenges in adopting the traditional land reclamation methods for futureland reclamation works due to new technical difficulties and environmental constraints. Newapproaches are required to deal with new challenges and preserve marine ecosystems. In thispresentation, some new concepts and solutions that have been or could be potentially adopted fornew generation of land reclamation projects will be presented. These include methods for use ofclay slurry or soft materials for land reclamation, methods for the construction of non-dredgingseawalls, and land reclamation methods without use of fill materials. Some ideas for enhancing themarine eco-system as part of the land reclamation processes will be introduced.
Hong Kong-Zhuhai-Macao bridge link immersed tunnel and artificial island
Hong Kong-Zhuhai-Macao Bridge (HZMB) link locates at China south sea, connects Hong Kong onthe east and Zhuhai/Macao on the west. It has a total investment of HK$182 billion; it was openedto the public this year and dreams of decade comes true of shortening the surface transportationtime from 4hr+ to 0.5hr in the greater bay area with a population of over 60 million people; the linkis the longest as-build tunnel-bridge crossing. The vital work is the 6.7km long immersed tunnelthat set the record of the longest highway immersed tunnel in the world, and the two artificialislands on its both ends, each island was built in offshore condition and has a land area ofapproximately 100,000 m2. Environmental challenges of this project are high-volume cargo, habitatto endangered species, natural disaster zone, and severe sediment. Technical challenges are shortconstruction period, accurate work under 47m deep water, 22m thick cover of the tunnel that is anextremely high overload for the design of immersed tunnel structure, 30m thick layer of soft soiland the thickness varied locally, large section concrete cast and incremental launch. The projectwas taking-over on February this year and immediately received annual award from NCE, ENR andITA. This presentation aims to introduce several sustainable and innovative solutions developed inthe design and construction for resolving these unprecedented engineering challenges.
Design and Construction of Large Caisson Structures in Port
Caisson structures are very common and widely adopted in marine structures for soil retaining,berthing and mooring structures, and breakwaters. It was also used in the edge structures for theland reclamation for Finger 1 to 3 container terminals currently under construction in Singapore.Along with the increasing demand for deeper water depth to accommodate larger and largervessels, the size of caissons becomes bigger and bigger. Self-weight of the caissons also increasesfrom about 1000 tons before up to 30,000 tons nowadays. Configuration of caissons varies fromrectangular shape, circular shape to special type of L-shape, arc cell shape and etc. In terms ofconstruction, caissons are normally pre-fabricated by slip form or layer-by layer in precast yard ordocks in dry condition, and transported to the installation locations by towing in floating or bysemi-submerged barge. This presentation aims to share with the participants our experience in thedesign, precast, transportation and installation of large caissons.
Abstract
Crest level design and wave overtopping for coastal structures
Climate change and sea level rise may cause more extreme storms as well as larger waveovertopping at existing coastal structures, like breakwaters and quay walls. Guidance on waveovertopping is essential: in assessment or designing the crest level as well as in what is allowableovertopping. The best guidance is the EurOtop (2018) wave overtopping manual. Allowable waveovertopping is very much related to the wave height that causes this overtopping. In that sensehigh waves are much more damaging than small waves, even if the wave overtopping discharge issimilar. Guidance is given on overtopping discharge for sloping type structures like dikes, for rubblemound breakwaters and for vertical structures. This guidance consists of design formulae, but alsoan Artificial Neural Network is available for prediction. Finally, the new set-up of EurOtop Livechallenges researchers and practitioners to improve the manual on aspects and these will be, afterthorough review, be implemented in the next version that will be submitted every two years. In thisway it will become a living document, supported by international collaboration.
Hong Kong Airport’s Third Runway – Land Reclamation Project
Hong Kong Airport Authority (HKAA) embarks on the development of its third runway as theexisting two runways are reaching their saturation point. The total investment is projected to bearound HK$141.5 billion kicking off with ground improvement contracts on 1st August, 2016. TheMain Reclamation Contract (Contract 3206) commenced on 3rd October, 2016, awarded to ZHEC-CCCC-CDC JV, with a contract sum of HK$15.2 billion. 3206 Contract comprises the construction of13.13km of seawalls (sloping + vertical), ground improvement works like Prefabricated VerticalDrains (PVD), Deep Cement Mixing (DCM), vibro-compaction, stone columns and close to 100million cubic meters of fill material, reclaiming 650 hectares of land.This is the second non-dredge reclamation project being carried out in Hong Kong. Thispresentation aims to highlight the capability of CCCC/CHEC/CDC in the reclamation projects, withvarious plant & equipment and techniques under various constraints to overcome many challengesunder the most unusual environment.
Methods for the development of large floating artificial islands
Journey to the Deep, Large Floating Artificial Island is the future. The proposed project aims todevelop a series of key techniques of construction of large floating artificial island, and attempt toconduct some pilot projects along the coast line at Indian and Pacific Oceans. The research will beextended using the theoretical analysis, numerical simulation and physical modelling methods,including: establishing information database of general condition in the construction of largefloating artificial island in the representative areas; proposing the solution to construct the floatingisland using modular approaches. Emphasis will be given to the development of novel subseafoundation systems (details will be presented), multi-points mooring line system to support thefloating structure, floating breakwater and marine ecosystem protection measures. The findings ofthe research can give a construction guideline, and guarantee the safety, stability of green andenergy-saving large floating artificial island.
