This paper shows the use of in situ dilatometer (DMT) testing in the analysis of the stability of clay slopes. In particular, a method is presented for detecting slip surfaces in overconsolidated (OC) clay slopes based on the inspection of the profiles of the horizontal stress index (Kd) from DMT. A number of case histories are presented where the slip surfaces signaled by the DMT-Kd method were confirmed by inclinometer measurements. The method provides a fast response in locating the position of active or quiescent slip surfaces.

Abstract

This paper shows the use of in situ dilatometer (DMT) testing in the analysis of the stability of clay slopes. In particular, a method is presented for detecting slip surfaces in overconsolidated (OC) clay slopes based on the inspection of the profiles of the horizontal stress index (Kd) from DMT. A number of case histories are presented where the slip surfaces signaled by the DMT-Kd method were confirmed by inclinometer measurements. The method provides a fast response in locating the position of active or quiescent slip surfaces.
