VIBRATORY PILE DRIVING AND SOIL PROPERTIES
VIBRATIONSRAMMUNG UND BODENBESCHAFFENHEIT
This paper provides a comparison between vibratory pile driving and conventional impact driving as well as information on difficulties arising in vibratory driving. The historical development is thus: machine foundations, load plate with vibratory excitor, the influence of the frequency. By means of vibration, cohesionless soils can be converted into a pseudo-fluid condition; thus the friction and drainage resistance in the soil is reduced. The paper covers electrical vibrating rods with adjustable or non-adjustable out-of-balance, some with graded frequency regulation; vibrating mechanisms, rotative moment, excitation force, number of revolutions per minute, the influence of the soil on the effect of vibratory driving. Also covered is the influence of the speed of rotation for any particular type of soil, the important role of empirical dimensioning in cohesionless soils; aggregate sizes and compaction, and for cohesive soils, the cohesion (clay content and consistency water content). Practical reference values for vibratory driving are given, test results, general fundamentals for use in practice, problems and outlook. (TRRL) (TRRL)
