The AD Cam-Clay project takes its name from the .ad, which identifies Andorra as a country on the Internet and Clay of a recognized constitutive model and widely used in the science of soil mechanics. The description of the objectives is structured in three sections. Type of research to be developed and the research elements. Brief explanation of the research project and conceptual model. Tools of research to use and case study. 1st) Type of research to be developed: This project aims to enter the field of fundamental research. The project aims to develop an explanatory and predictive mathematical model. The mathematical model is based on an existing conceptual model that can be improved according to seconds the results obtained in mathematical modeling. 1b) The subject of the research: The subject of the research is a material of a geological or geomaterial nature, widely known in the Principality and geologically called "Till". In the slang of the country this geomaterial is described as "Rock in formation" or "decompose rock" due to its hardness as well as its ability to generate landslides, failures in buildings, cracks in walls, or their ability to confine groundwater. The target geomaterial is a rock and not a rock. It corresponds to a sediment deformed by the old glacier of Andorra and which has a significant amount of untreated data, under the tutelage of the Marcel Chevalier Private Foundation. Geomaterial behaves differently depending on how it has been previously deformed (with water or without), and the place in the valley where it has been deformed as well as the depth at which it has been deformed. Numerical data on the behavior of geomaterial are known from the results pressure testing. This type of test is standardized and makes it easy to compare results incl s between distant geographical areas. 2a) Summary explanation: The project aims to develop a model that explains the values of deformation, due to the so-called preconsolidation pressure, which is observed in glacial deposits by a given from the small Andorran glacier. 2b) Conceptual model: The dynamics are related to an accumulation of sediment and acorns at the bottom of the valley of Andorra, accompanied by a flow of groundwater generated by the melting of the ice. This water flow generates a pressure difference between the upper parts of the glacier and the discharge point at its front. In this context, the sediment at the bottom of the valley is submerged within an effort field tangential, developed by the friction exerted by the base of the glacier in displacement.
