Ir. Dr. Chan Swee Huat is a registered Professional Engineer with the Board of Engineers, Malaysia since 2005. He graduated with a 1st Class Honors Degree in Civil & Structural Engineering from the Universiti Kebangsaan Malaysia in 1997. He obtained his Ph.D degree from the National University of Singapore in 2003. He worked as a Geotechnical Engineer in SSP Geotechnics Sdn. Bhd. for about 5 years before he joined Dr C.T. Toh Consultant as a Resident Engineer for about 2 years. He is currently a lecturer in the University of Nottingham Malaysia Campus, responsible for teaching the geotechnical engineering and critical state soil mechanics. He also serves as an advisor to Geo-Excel Consultants Sdn. Bhd., a geotechnical engineering consulting firm. For the past 13 years, he has involved himself in analysis, design and construction of various geotechnical works and aspects including shallow & deep foundations, deep excavations & earth retaining structures, slope stability analyses & stabilization, landfill liner systems, seepage analyses, assessments of tunneling methods, soil improvement techniques (highway, railway, airport, etc.), geotechnical failure investigations, 3-D finite element analyses, etc.

Current Research
Dr. Chan's current research focuses on development and improvement in the design and construction aspects of some common geotechnical engineering works in the construction industry. Most of the research outputs are intended for practical civil engineers to improve their knowledge and competency in carrying out design and construction works. The followings are some research areas which he is currently looking at:

(a) Bearing and Settlement Behaviours of Piled-rafts in Soft Clay
The piled-raft is a foundation system consisting of three elements, i.e. piles, raft and soil. The full detailed analysis of a piled-raft is not trivial due to its three-dimensional nature and the complicated interactions among piles, soil and raft. The conventional design of piled-rafts often conservatively ignores the contribution from the raft, and assumes that the pile carry all the imposed loads. As a result, the conventional piled-raft designs are often conservative. The objectives of research are to
(i) Study and understand the soil-structure interactions, bearing and settlement behaviours of piled-rafts in soft clay using 3-D finite element analyses, so that more economical piled-raft solutions can be obtained by including the contributions from the rafts; and
(ii) Develop simplified techniques and/or design charts to permit a rapid preliminary assessment and design of piled-raft for project planning and cost estimation purposes.
Currently, a PhD student is working on this research topic.
(b) Improving Settlements and Bearing Capacities of Shallow Foundations
Shallow foundations transfer building or structure loads to the ground near the surface, generally not more than 3.0m. Shallow foundations include pad footings (can be circular, square or rectangular in shape), strip footings and raft foundations. Shallow foundations are generally designed to satisfy bearing capacity and settlement criteria. If the founding soil at shallow depths is weak, shallow foundations become inadequate, then pile foundations, which are often much more expensive, will have to be used. This research proposes to use an embedded key wall, which to be placed along the perimeter of the shallow foundation, to improve settlements and bearing capacities of the shallow foundation. Finite element analyses show very positive results in the preliminary study. The research is still in progress.

3-D Finite Element Modelling and Full Scale Measurements of Pullout Capacities on Single-Plate and Multiple-Plate Discrete Deadman Anchors
A deadman anchor is a buried object in ground (behind an earth retaining wall) used as an anchor to hold back the earth retaining wall from excessive lateral movements. A deadman anchor can be continuous (e.g. steel sheet piles, strip beams, etc.) or discrete/individual (e.g. driven piles, concrete blocks, etc.). The numerical analyses of continuous deadmaan anchors can be simplified to plane-strain two-dimensional (2-D) models, and the pullout capacities of continuous deadman anchors can be predicted reasonably well. However, discrete deadman anchors are three-dimensional (3-D) in nature, and can only be simulated realistically using 3-D models, such as 3-D finite element method. This research aims to perform 3-D finite element modelling and full-scale measurements of the pullout capacities of single-plate and multiple-plate discrete deadman anchors.
