Abstract
The ground surrounding a cavern generally shows not only continuous behaviours but also discontinuous behaviours of slip and spalling along various types of discontinuities.
Sakurai and his co-workers have proposed a method of back analysis of measured displacements by introducing the anisotropic parameters in stress-strain relationship, which enables to introduce such a discontinuous behaviour in the framework of continuum mechanics.
The authors have applied this method of back analysis to analyze the behaviours of a large underground cavern of the Cirata Hydroelectric Power Project in Indonesia.
In this paper the results obtained in this analysis are shown and discussed.
