Abstract
Geotechnical construction encounters many unexpected troubles, and one of the important reasons for this is the lack of subsurface information and knowledge. This paper calls the troubles “georisk” and exhibits that more subsurface investigations have to be practised in order to reduce this risk. Case history data was interpreted as a collaborative work with several institutions, and it was demonstrated that the risk can be mitigated by allocating more budget to the investigation. Another source of risk is the lack of knowledge, and one needs to pay more attention to the history of troubles that were experienced during projects in the past.

The present study on georisk management was carried out as a collaboration among the Japanese Geotechnical Society, the Georisk Society and the Japan Geotechnical Consultants Association. The case history data was collected by the long-term efforts of the Georisk Society. The author expresses his deepest appreciation to these institutes as well as Prof. T. Watanabe who is the President of the Georisk Society.
