For buildings and factories located near railway or subway lines, the vibrations caused by the moving trains, especially at high speeds, may be annoying to the residents or detrimental to the high-precision production lines. However, there is a lack of simple and efficient tools for dealing with the kind of environmental vibrations, concerning simulation of the radiation of infinite boundaries; irregularities in soils, buildings and wave barriers; and dynamic properties of the moving vehicles. This book is intended to fill such a gap.Compared with the boundary element method (BEM) for solving the half-space problems, the finite/infinite element method (FIEM) presented in this book has the following advantages:• It requires less effort in formulation and computation.• It can be directly incorporated in an existing FEM analysis program.• It is capable of simulating the irregularities in buildings, soils and tunnels.• It can be used to evaluate the efficiency of various wave barriers for vibration reduction.The methodology presented in the book can be adopted to analyze the vibrations caused by road traffic as well.

Two numerical applications are performed to predict the load capacity of single piles in normally consolidated clays. It is observed that the model with no slippage at the interface predicts almost twice as much load capacity as the model with interface. In regards with the end bearing capacities, Coyle & Castello's method is found to be most conservative followed by the finite element method, the Janbu's method, the Meyerhof's method, and finally the Vesic's method. In respect to skin friction resistance, the finite element is found to be the most conservative method, followed by the Beta, the Lambda, and the Alpha method. In the dynamic analysis, the amplitudes of ground vibrations are investigated based on the variation of: (1) the soil type, (2) the pile embedment length and (3) the released hammer energy. In the first analysis, five types of soils - loose and dense sands and, soft, medium stiff, and stiff clays - are modeled. The highest vibration amplitude is calculated for the loose sand with a peak particle velocity (PPV) of 10.0 mm/s followed by the dense sand with a PPV of around 4.0 mm/s. Among the clay types, the vibrations are higher for the stiffer clay in the near field, which is 9 m (half a pile length) or less away from the pile. In the second analysis, three different embedment lengths - full, half, and quarter pile length - are modeled. It is found that the quarter embedded piles produce greater vibration amplitudes as compared to the half and fully embedded piles. Larger amplitudes of vibrations are encountered on the ground surface for shorter pile embedment lengths. In the third analysis, three different impact forces consisting of 2,000 kN (F), 6,000 kN (3F) and 10,000 kN (5F) are applied on the pile head. It is concluded that increase in hammer energy causes increase in the peak particle velocities.

"This volume contains 101 papers presented at the 8th International Conference on the Application of Stress Wave Theory to Piles, held in Lisbon, Portugal in 2008." "It is divided in 14 chapters according to the conference themes: Wave mechanics applied to pile engineering; Relationship between static resistance to driving and long-term static soil resistance; Case histories involving measurementand analysis of stress waves; Dynamic monitoring of driven piles; Dynamic soil-pile interaction models - numerical and physical modeling; High-strain dynamic test; Low-strain dynamic test; Rapid-load test; Monitoring and analysis of vibratory driven piles; Correlation of dynamic and static load tests; Quality assurance of deep foundations using dynamic methods; Incorporation of dynamic testing into design codes and testing standards; Ground vibrations induced by pile motions; Dynamic measurements in ground field testing." "This conference aims to contribute to a better and more efficient professional interaction between specialized contractors, designers and academicians. By joining the contribution of all of them it was possible to elucidate the today's state-of-the-art in science, technology and practice in the application of stress wave theory to piles."--BOOK JACKET.

Detailing the proceedings of the Wave 2002 workshop at Okayama University in Japan, this collection of eighteen peer-reviewed papers concerns the issue of the ground vibration and noise caused by construction activities, explosions in the ground, or high-speed trains. Providing key information for engineers, researchers, scientists, practitioners, teachers and students working in the field of structural dynamics or soil dynamics, this text also includes a useful address list in the appendix to enable readers to gather further information if required.
