Determination of K0 in Aged Clays Using Marchetti´s Flat Dilatometer
Original language description
This study deals with the determination of the earth’s pressure coefficient at rest “K0” by field measurement using Marchetti´s flat dilatometer (DMT) in aged clays. Generally, it is a complicated task to determine K0 coefficient in a natural soil let alone in aged clays. In these cases, all available techniques for determining of K0 are affected by non-negligible imperfections and uncertainties which leads to unrealistic results. However, this fact is often ignored. For example, the original Marchetti´s formula for computing of K0,DMT is widely used for all types of soils, despite author´s warnings about the limited usability for soils affected by aging effects. This study shows an effective approach how to determine K0 coefficient. It is a combination of the determining of K0 by using back numerical analysis (BNA) and field measurements by DMT which leads to a more realistic result. The proceeding describes a case study on aged clays of the Carpathian Foredeep in the Czech Republic. The main finding is that the original Marchetti´s formula gives noticeably distorted results. On the other hand, the so-called Kouretzis´ equation seems to be applicable for old clays.
