Large dams, especially concrete dams, have been designed against earthquakes since the construction of Hoover dam in the 1930s. The design criteria and methods of analysis used in those times are outdated today and the actual seismic safety of these structures is not known in view of today’s requirements. Earthquake action was usually taken into account pseudostatically, through an inertia forc...

The present paper examines the use of optical fiber as a distributed temperature sensor to detect leaks in earth dams. This real-time data acquisition technique complements current auscultation systems and improves monitoring these critical infrastructures. aim this is provide practical illustration novel promising and, particularly, precautions consider correctly deploy elements. For last purp...

earth dam is a structure as homogeneous or non-homogeneous forms for raising water level or water supply. earth dam consist of different parts that one of the main parts is clay core. choosing an optimal non permeable core which causes reduction of seepage through dam body and also being stable is necessary. the objective of this research is to optimize the geometry of earth dam clay core such ...

This paper presents the results of experimental studies on deformation and strength anisotropy gravel-pebble soils used in soil dams. During stabilometric tests, varying shear angles were obtained for stone at different orientations particles working chamber, whether horizontal or vertical. As hydrostatic pressure chamber increased to 0.8 MPa, a reduction by 8-12 degrees depending direction lay...
