P1- Application of Pile Driving Analyzer (PDA) and CAPWAP Analysis to Bearing Capacity of Pile
Abstract: This paper presents briefly the application of dynamic pile testing to bearing capacity determination of a pile embedded in loose to compact sand and silt layers. The possibility of liquefaction of the loose layers as a result of cyclic loads such as earthquake, and therefore, reduction in shaft res...
Abstract: In liquefaction, the strength of the soil decreases, and, the ability of a soil deposit to support structure foundations for buildings and bridges is reduced. One of the major factors of lifeline damage in earthquakes is ground failures caused by the liquefaction of loose, saturated cohesionless so...
Abstract This paper evaluates the bearing capacity and failure mechanism of micropile groups in sand and clay. Micropiles are small-diameter piles (typically less than 300mm) that are generally used for structural support, underpinning, and in-situ earth reinforcement. The goal of this study was to compare the performance of ...
nowadays, using deep foundations is needed more than ever due to the increasing population and lack of suitable soils pile driving is the oldest and one of the most reliable methods of pile installations unfortunately environmental problems and vibrations induced by pile driving have limited the use the pile driving in urban ...
Abstract Construction activities like pile driving, dynamic compaction, or blasting can be the sources of adverse effects on adjacent structures and sensitive installations. It is often suggested that vibrations can be interrupted using wave barriers. The properties of barriers affect their efficiency. In this research, the p...
Abstract: Gelevard dam is one of the under-construction dams in Iran. Gallery tunnels have been executed to implement the possibility of an appropriate grout curtain, complete sealing of support, and dam foundation. The current paper has studied and analyzed the left bottom gallery (LG3) with a length of 380 ...
Abstract: Impact hammers and vibratory drivers are used for piles and sheet pile installation. Dynamic loads force piles to vibrate and penetrate into the ground which results in soil displacements and vibrations around a pile. The soil movements may produce settlements in sandy ...
Abstract: This paper describes a new one-dimensional finite element model for pile driving in soft rock. The approach of Smith (1960) is used to simulate the pile driver system. The pile is assumed to be elastic, linear, and vertical. It is also discretized into a number of simpl...
