Determinación de la capacidad portante de arcillas duras y lutitas en la zona costera de Ballenita en base a pruebas de carga dinámica.

Abstract

In Ecuador, drilled shafts are used for deep foundations for all types of structures either in bridges or buildings, which are very important structures that must support loads suitably. For this, the use of "Pile Dynamic nalysis" (PDA) tests with the corresponding "Case Pile Wave Analysis Program" analysis (CAPWAP) has been implemented, being increasingly used in our country. This test is the most appropriate way in the field to evaluate the ultimate capacity of the pile and its integrity. In the following titling work, the data of the project under construction of the Ballenita seawall viewpoint, located in the province of Santa Elena, was used, which was implemented using drilled piles. The study of soils at 10 meters depth shows a material that has the characteristics of a hard clay or a decomposed shale, so it was convenient to do dynamic load tests on three piles to verify that the load capacity of the pile is greater than the demand of the viewpoint. Subsequently, last capacity calculations were performed using the Aurora and Reese method (1976) and the drained and untrained methods of the (FHWA, 2010) manual, in order to compare which of these methods simulates the conditions of the PDA tests, taking into account that The literature for the calculation of this type of material is limited.
