2006 Graduate Catalog and 2005 Annual R & D Report
Sirindhorn International Institute of Technology (SIIT)
programs will be arranged to study the behavior of
pre-cracked reinforced concrete members. Here, we
classify the target members into 2 cases; that is, RC
members governed by concrete compression failure
(deep beams, beams with transverse bars) and RC
members governed by concrete tension failure (lightly
reinforced beams, beams with no transverse bars).
The aim is to formulate a universal theory that
explains both the compression and tension behavior
of pre-cracked RC elements and members.

M.Eng. in Geotechnical Engineering Program, Asian Institute of Technology (AIT), Thailand

Areas of Specialization: Numerical methods in geotechnical engineering; Mass transfer through porous media
and its application to geoenvironmental problems; Underground space development and tunneling.
Research Interests:
Application of Coupled Processes to
Geo-environmental Engineering
Many geo-environmental problems, including nuclear
waste repository and sanitary landfill problems,
involve three physical processes: mechanical, thermal
and hydrological. Though one of these three physical
processes plays a more dominant effect on the
response of the system, the effect of the remaining
processes may not be neglected, and a coupling of
one or more processes is required for engineering
analysis. The primary objective of this research is to
model various geo-engineering problems using a
coupled approach.
Soft Computing: Artificial Neural Networks, GIS,
ANP
Geological engineering is often considered as an
imprecise area of civil engineering. Artificial neural
network can be a useful tool to deal with geotechnical
'black-box' problems. Major focus is on the application
of Geographic Information Systems (GIS) to the field
of geo-environmental engineering. Applications of
ANP and BPNN within the GIS framework are under
consideration.
Tunneling and Underground Excavation
In rock tunneling, research interests are mainly in the
area of stress distribution around underground
openings, numerical analysis, geotechnical monitoring
and tunnel safety. In soft ground tunneling, major
concerns are ground deformation around openings
and settlement due to subsurface excavation.

Assistant Professor
B.Eng. in Civil Engineering, Chulalongkorn University, Thailand
M.Eng. in Transportation, Asian Institute of Technology (AIT), Thailand
Ph.D. in Transportation, Tohoku University, Japan
Areas of Specialization: Life Cycle Assessment (LCA) of transportation and infrastructure; Transport and
environment; Input-Output modeling, and applied economic modeling for transport; and Multicriteria decision
making.
Research Interests:
Multicriteria Decision Making in Civil Engineering
The current research interest focuses on applications
of multi criteria decision making techniques to solve
civil engineering problems. Possible topics include
engineering design, prioritization and evaluation of
public measures, classification problems, etc. Some
research topics require knowledge and cooperation
from multi-disciplinary fields. Examples of research
being conducted include highway corridor planning,
prioritization of highway accident reduction measures,
landslide/seismic hazard zoning, seismic resistance
and maintenance prioritization of existing buildings.
Techniques such as the Analytic Network Process
(ANP) and Fuzzy Decision Making Methods are used
to solve the multicriteria decision making problems.
Highway Design Optimization
Highway design is a complex process that involves
many constraints and objectives to be achieved. The
conventional design method is manual. Therefore the
number of alternatives is limited by the choices of the
designer. It is also time and cost consuming to
generate many alternatives by manual design. The
research aims to apply some heuristic techniques
such as Genetic Algorithm (GA) and Ant Colony
Optimization (ACO) to solve the highway design
optimization problem within the Geographic
Information System (GIS) environment.
