THIS RESEARCH PROJECT CONTINUES PART OF IRRD RESEARCH PROJECT 500192. ITS AIM IS TO DEFINE A METHODOLOGY FOR STUDYING EMBANKMENTS ON PEAT. IN THE PAST, SEVERAL EXPERIMENTAL EMBANKMENTS HAVE BEEN BUILT ON THIS TYPE OF SOIL (CAEN, IWUY, BOURGOIN, ETC). PARALLEL BIBLIOGRAPHIC STUDIES GAVE A BETTER KNOWLEDGE OF PEAT (CHEMICAL COMPOSITION, STRUCTURE, DEGREE OF DECOMPOSITION). IN 1978 IT IS ENVISAGED TO STUDY THE BEHAVIOUR OF AN EMBANKMENT ON PEAT (MOISTURE CONTENT: 500 TO 1000%) IN LOURDES AND TO CONTINUE THE INVESTIGATIONS ON THE INFLUENCE OF THE STRUCTURE AND INGREDIENTS OF PEAT ON ITS BEHAVIOUR WITH A VIEW TO GAINING A BETTER KNOWLEDGE OF CONSOLIDATION AND CREEP IN THIS TYPE OF SOIL. |
