Introduction

Geotechnical engineering is the subdiscipline of civil engineering involving natural materials found close to the ground surface. The subjects include basic material mechanics of the soil and rock, design of foundations, retaining structures and slope, tunneling, and other dynamic behaviors. The research of geotechnical engineering also covers engineering geology, geophysics, hydrology and other related fields.

The geotechnical engineering division of NTU can be traced back to the early stage of CE graduate program established in 1960, with some graduate students conducting their researches in soil engineering. The division was formally established in August 1985. Since then, the discipline has extended to include broader research areas such as rock mechanics and engineering geology. Faculty members in the division are with post-graduate degrees from renowned Universities, well experienced, and with distinguished researches in related fields. The division also provides abundant facilities such as laboratories for soil mechanics, rock mechanics, foundation engineering, and engineering geology

Vision

Considering the fragile geological conditions, frequent typhoons and earthquakes of the natural environment in Taiwan, the fundamental researches in soil mechanics, foundation engineering, soil dynamics rock mechanics and engineering geology, will be strengthened. In responding to the topics with local concerns, researches will focus on earthquake engineering, slope stability, environmental geotechnique, foundation engineering, tunnel and underground spaces development and GIS applications, and to move further toward internationally concerned topics.
Research topics will be modified according to short-term and long-term needs. The division is dedicated to motivate itself to become the leader in the following research fields:

(1) Foundations and underground spaces engineering

(2) Environmental geotechnology and sustainable development

(3) Integrated research on geotechnical hazards

The division also provides social services actively to the important issues such as geotechnical hazards mitigation, early warning, and land use planning.

Students of the division are encouraged to explore and pursue issues encountered in practice, which helps to build up confidence, and to become leaders in the profession.
