<strong>Seminar</strong> on “Tunnelling Technologies in Japan and Hong Kong” – 22 September 2010 

FOREWORD 

The seminar today is part of the project aims at enhancing the knowledge of Hong 

Kong engineers on state-of-the-art technology and experience in civil and geotechnical 

engineering in Japan, especially on the latest innovative technology on the construction of 

tunnels. 

Japan has been well-known for its tunnel design and construction technology. We are 

thus very fortunate that a delegation of Japanese tunnel experts have kindly accepted our 

invitation to share their experience on tunnel design and construction latest technology by 

presenting their papers in the seminar. 

The financial funding from the Government of Hong Kong Special Administrative Region 

under the Professional Services Development Assistance Scheme to support this seminar 

and the associated visit to Japan in January 2010 is gratefully acknowledged. 

On behalf of the Geotechnical Division, I would like to express my sincere thanks to all the 

Japanese experts for their contributions in preparing the technical papers and presentations. 

I would also like to thank the effort from the Organising Committee of this PSDAS seminar, 

in particular the efforts of Ir W K Pun, Ir Albert Ho and Ir Dr Eric Li.

MESSAGE FROM PRESIDENT OF 

THE JAPANESE GEOTECHNICAL SOCIETY 

On the occasion of the “<strong>Seminar</strong> on Tunnelling Technologies in Japan and Hong Kong”, 

I would like to offer my congratulations to the Hong Kong Geotechnical Society and the 

Hong Kong Institution of Engineers. 

The Japanese Geotechnical Society (JGS) was set up in 1949 with 122 members to promote 

technical advances and research activities in the field of geotechnical engineering. 

As a member society of the International Society for Soil Mechanics and Geotechnical 

Engineering, the society now has about 10,000 members and has become one of the most 

active and largest societies among over 100 societies in Japan. 

This time I feel honored that three experts from the JGS were invited to this important 

seminar. Since they actively work and continuously contribute to the field of the tunnelling 

technology in Japan, I would expect that their presentations provide helpful information 

and knowledge for participants in the seminar. Finally, I would like to express my sincere 

gratitude to all the staff who have devoted themselves to this memorable seminar. 

Professor Osamu Kusakabe 

President 

The Japanese Geotechnical Society
