Ground Response during Pile Driving

Abstract

The paper presents a synthesis of the field measurements obtained in a series of large-scale pile-driving tests. The field test was performed at the Chiayi-Taipo area of the high speed rail system currently under construction in Taiwan. The test project included a complete instrumentation of three precast concrete piles with a network of piezometers, inclinometers, level posts, and velocity sensors. The instruments were used to monitor the variations of the dynamic soil pore water pressure, lateral ground deformations, vertical surface displacements, and ground vibrations induced by the pile on the surrounding soil medium during the driving process. Based on the test results, a correlation between the pile-driving resistance and the geological condition of the test site is identified.
