Abstract

The authors have been involved with the stability problem of the karstic caves beneath Gushikawa Castle remains in Okinawa Island of Japan using different techniques available in rock mechanics and rock engineering. First, several rock classifications were used for the characterization of rock masses surrounding these karstic caves on the basis of geotechnical investigations. Then, some stability assessments of caves were carried out using empirical and analytical techniques. Numerical analyses showed that filling the cavities would increase the safety of the natural rock structures and it was decided to fill the cavities. Furthermore, a monitoring scheme was undertaken to observe the response of cavities before and after filling operations and to see the effectiveness of cavity filling on the stability of the caves.
