2019 Keynote Address




Keynote Speaker (1)


Dr. Hiroshi Uechi

Faculty of Commerce

Osaka Gakuin University
Introduction
Hiroshi Uechi, Ph.D.  He obtained his doctoral degree in nuclear physics (theoretical nuclear physics) from Indiana University, USA, under the guidance of Professor Brian D. Serot who founded the nuclear field theory, quantum hadrodynamics (QHD) with Professor John D. Walecka. Currently, he is a professor at Osaka Gakuin University and has been working on nuclear many-body theory and nuclear astrophysics.
He has been investigating self-consistent QHD hadronic approximations in terms of Landau’s Fermi-liquid theory and density functional theory (DFT) while applying QHD nonlinear and chiral effective models to neutron star calculations. He is working on nonlinear mean-field and chiral mean-field method for nuclear matter, self-consistent approximation method beyond mean-field approximations.

He has more than 25 years' experience in the field of Geotechnical Engineering, especially Foundations, Ground Improvement and Geotechnical Forensics Engineering and have wrote more than 100 technical papers and Journals related to his field of expertise. He is also a Professional Engineer who have numerous experience as a Design Engineer, Design Checker and Geotechnical Technical Advisor to various government and private agencies and also involved in many Civil Forensic works including Structural and Infrastructures in Malaysia. He also provides an expertise support for Standards and Industrial Research Institute of Malaysia (SIRIM) and Public Work Department (JKR), in the design specification work for specialized work such as Soil Anchor and Load Testing.


Keynote Title: Taking Risk in Geotechnical Engineering Design: Do We Learn from Failure?

Abstract

Soils are human in nature. Uncertainties, history, colours and background dominates the behaviour of the soil. Understanding its behaviour is a complicated task. Prediction on its behaviour is the best solution offer so far without any assurance on its performance. Terzaghi(1936) once said , “soils are made from natures and not by man, and the product of natures are always complex”. Many uncertainties involves in predicting the behaviour of soils. From extracting, handling and testing which bound to accumulate errors and disturbance to the sample, will cause a deviations from its actual behaviours. Question will arise from a designer as representative samples taken from site may not resembles at all since statistically only a small portion is being taken from a large area. Geotechnical Engineering fields are related with daily life. Slopes, foundations, excavations, flood barrier, anchoring to name a few are geotechnical construction that needs high safety design for the comfort of the public. Engineer must struggle to design in such a way as to avoid failure, which could result in loss of property, damage to the environment of the user of that technology, and possibly injury or even loss of life. However, failures in Geotechnical construction seems to be a common scenario nowadays. Some catastrophic events involving loss of lives periodically remind people that the notion of zero risk and of completely guaranteed safety does not exist. From common structural settlement to a mass slope failures, many Geotechnical Designers have come forward with various state of the art in rectification works at the design stage to obtain better and safer constructions to the public. The design and constructions has been improvised in lieu to the lesson learn from the previous failure. New developments in design are often the direct consequence of lessons learnt from previous failures, which are caused when the designers went too far beyond the state-of the art or the contractors did not implement the design intent in the construction. This combination with increase in knowledge and development of new materials actually led to the occurrence of more failures, principally as a result of enhanced demand for many types of novel structures for which there were no historical precedents. There is no question that the trial-and-error process of designing and constructing, over the centuries, resulted in the loss of properties and life. It is not that failure is desirable, or that anyone hopes for or aims for it. But failures, sometimes appalling, are inevitable, and given this fact, engineers say it pays to make good lesson learned to prevent any possible future mistakes. This keynote address will focus on the risk of geotechnical hazard which lead to the necessity of understanding its behaviour which cause the failure for future improvement of the construction.
