Effect of Pile Driving on Ground Vibration in Clay Soil: Numerical and Experimental Study

In this study, peak particle velocity (PPV) values for driving three piles with diameters of 40 cm, 50 and 70 cm in a clayey soil through the impact piling method are investigated by an experimental study numerical simulation. An is carried out on scale 1:20 operation. Numerical simulation performed using axisymmetric model PLAXIS 2D finite element software. Properties used obtained from geotechnical tests employed The has been verified comparing acquired PPV those measured study. results show good agreement between computed data. Moreover, velocities indicate that increase diameter pile can level ground vibration. Some sensitivity analyses have modeling to determine effect properties changes PPV. Also, friction angle reduction elastic modulus will amount at distance 100 about 10.33% 25 site 3.5 cm. addition, 2.5 2 equal 8.31% 12.77%, respectively.
