STUDY OF SMALL DAMS

ETUDE DES DIGUES DE FAIBLE HAUTEUR

THE OBJECT OF THIS RESEARCH IS TO DEFINE A STUDY PROCESS FOR SMALL DAMS WITH A VIEW TO DRAFTING RECOMMENDATIONS CONCERNING THIS TYPE OF STRUCTURE. THE SURVEY ON DAMS CARRIED OUT BY THE LABORATOIRES DES PONTS ET CHAUSSEES OF THE PARIS REGION LED TO THE DEFINITION OF TYPICAL STRUCTURES DEPENDING ON THE SUBGRADE GEOMETRY. MEASUREMENTS WHICH WILL BE STUDIED FOR DIFFERENT CONDITIONS OF FLOW AND MADE ON TWO EXISTING STRUCTURES GAVE INFORMATION ON FLOWS IN THE DAM STRUCTURE. IN 1979 IT IS PROPOSED (1) TO STUDY THE STABILITY OF THE STRUCTURAL TYPES ALREADY DEFINED BY VARYING THE HYDRAULIC AND MECHANICAL CHARACTERISTICS OF THE SOIL; (2) TO CONTINUE OBSERVATIONS ON REAL STRUCTURES ESPECIALLY IN THE CONTEXT OF THE FILLING OF A 15 M HIGH DAM.
