ON THE INTERNAL STRESSES IN GRAVITY DAM UNDER SEDIMENTARY PRESSURE

Internal erosion under spillway rested on an embankment dam

In this paper we investigate the mechanism of internal erosion caused in the right abutment of the Shahghasem dam’s spillway. Shahghasem dam is an earthen dam located in Yasouj, in southwest of Iran. A significant hole and pipe have been observed in the corner of the right abutment from upstream view. The foundation is Marlstone, which has low cohesion and susceptible for internal erosion and p...

Edge detection in gravity field of the Gheshm sedimentary basin

Edge detection and edge enhancement techniques play an essential role in interpreting potential field data. This paper describes the application of various edge detection techniques to gravity data in order to delineate the edges of subsurface structures. The edge detection methods comprise analytic signal, total horizontal derivative (THDR), theta angle, tilt angle, hyperbolic of tilt angle (H...

The Effect of Cut-off Wall on Seepage and Uplift Pressure under Earth Dam (Case Study: Shamil Dam in Iran)

Design of earth dams and their problems are important during construction and after it,because of their potential hazards and failure for downstream population. The dam foundation seepage control the the importance from the perspective of a major engineering project and explain the economic performance of each project is allocated. among activities that can be used to prevent piping phenomena a...

Effect of Material Gradient on Stresses of FGM Rotating Thick-Walled Cylindrical Pressure Vessel with Longitudinal Variation of Properties under Non-uniform Internal and External Pressure

The present paper provides a semi-analytical solution to obtain the displacements and stresses in a functionally graded material (FGM) rotating thick cylindrical shell with clamped ends under non-uniform pressure. Material properties of cylinder are assumed to change along the axial direction according to a power law form. It is also assumed that the Poisson’s ratio is constant. Given the exist...
