Application of Pile Driving Analyzer (PDA) and CAPWAP Analysis to Bearing Capacity of Piles

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...

A Case Study of Soil Improvement Against Liquefaction By Using Jet grout Technique

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...

Evaluating the Bearing Capacity of Micropile Groups in Different Soils Using Numerical Methods

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 ...

EVALUATION OF EFFECTIVE PARAMETERS ON VIBRATIONS INDUCED BY PILE DRIVING WITH FINITE ELEMENT METHOD

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 ...

Numerical Study on Effect of Barriers on Vibrations Induced by Construction Activities

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...

Three-Dimensional Analysis of Permanent Covering Behavior of Gelevard Dam Injection Gallery and Optimal Design of Tunnel Coverage

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 ...
