Diseño de anclajes de hormigon para deflexiones horizontales y verticales en tuberías apresión

Abstract

This paper presents the designs of different anchoring systems for pressure pipes through calculation programs made on Microsoft Excel. Six different kinds of anchoring systems are analyzed: Vertical anchoring concave, vertical anchoring convex, horizontal anchoring concave, vertical anchoring convex, vertical anchoring on foot slope and vertical anchoring on head slope. The calculation programs have an automatic part where the anchoring shape is assume to be square, and a manual part where the user can input the dimensions and check if they satisfy or not with the soil allowable stresses and with the balance of the anchor block. These programs were developed based on theoretical fundaments of hydraulics, mainly on the obtaining of hydrodynamic and hydrostatic forces that are generated inside a pressure pipe; structures, on the sizing of the anchor block and the amount of steel which is necessary for the balance of the forces; and soil mechanics where the ground resistance, active and passive pressure, and the friction between materials are considerate; these theoretical basis are collected within this document. All the information provided in this thesis will serve as support and to make faster the design of anchoring systems process mentioned above.
