A CRITICAL STATE APPROACH TO STABILITY OF CLAY SHALE FOR DESIGN STRUCTURES OF THE SENTUL HILL, WEST JAVA, INDONESIA
The article presents the results of detailed geotechnical and laboratory investigations which served as the basis for the model of a sliding, unstable slope in the area of designed structures at the Sentul Hill, West Java, Indonesia. On the basis of geotechnical profiles the stability analyses were carried out. As for the input data of stability analyses the results of unconfined compression and triaxial tests along with the modified Michalowski (1995) failure criterion were used. The critical failure was also accurately determined by means of inclination measurements and mineralogy of clay shale.
