SYNOPSIS
Traditional geotechnical engineering is indisputably founded on sound theoretical
engineering mechanics pioneered by Terzaghi since 1900. It’s based on input of ideal
engineering soil parameters. However, the conventional site investigation methods to
obtain these soil parameters suffers inherent problems such has stress relief during
sampling or in situ testing, sample disturbances during transportation, size of the sample
tested and the handling disturbances in the laboratory. In order to overcome all these
inherent problems, an alternative state of the art method using in situ shear wave
velocity and damping measurements have been developed for geotechnical applications
and will be the main course materials to be covered in this workshop.
In this workshop, basic theory of wave mechanics, the Spectral Analysis of Surface Wave
method (SASW) and with hands on SASW software applications will be given in order to
obtain the important soil parameters of shear wave velocity and damping. A SASW data
acquisition system will be demonstrated and thereafter hands on field work to be runned
in groups will enable the participants to record and collect these parameters in the field
and will help them to have quick evaluations of the soil properties of the site. The theory
on the applications of these soil parameters on the calculation of settlement, shear
strength and bearing capacity of shallow and deep foundations will be explained with
problem solving session for the participants using their respective data collected during
their field work session.
SPEAKERS
Prof. Sung-Ho Joh(Ph.D.) is a professor in the Department of Civil, Environmental and
Plant Engineering at Chung-Ang University, Korea. He got his Ph.D. at the University of
Texas at Austin in 1996. He has been working on the surface-wave technique more than
20 years. One of his accomplishments is the WinSASW, which is the software dedicated
to SASW test. His research includes the development of variety of seismic techniques
such as Pavement Integrity Scanner (PiScanner), ERS (Enhanced Resonance Search),
OSR (Optimized Shear-Wave Resonance), HiRAS (Hybrid Integration of Resistivity and
Stiffness), Short-Array Beam Forming (SBF) techniques. His applications of the seismic
techniques have been extended to site investigation, pavement evaluation, compaction
control, railroad track (ballast and concrete), health monitoring of concrete structures.
Khairul Anuar Mohd. Nayan (M.Sc.) is a senior lecturer in the Department of Civil and
Structural Engineering, Universiti Kebangsaan Malaysia. He has worked in Public Works
Department (1982 to 1996) where he was involved in designing and construction of
bridges, foundations design and latter in research on engineering geophysics. From 1996
to date he has been involved in the research and applications of the SASW method in
subsurface and pavement profiling, settlement, shear strength and bearing capacity
calculation and evaluations of shallow and deep foundations. He has numerous published
local and international proceedings and journal papers.
