Abstract | The present work is a compilation of a large number of projects in the field of soil vibrations where the vertical vibration velocity is viewed as a function of distance and charge weight. The compilation contains very heterogeneous measurement data since the results are based on various measuring techniques and instruments, and may also depend on individual interpretations of vibration values. Supplementary measurements have been made and one single relationship V=K/(R/VQ)[alpha] has been fit to all values. An examination of damage in buildings as a function of the magnitude of the vibrations has been carried out and compared with similar non-Swedish investigations. This shows that damage can occur at very low vibration values but that the probability of this occurring is small. At 50 mm/s the probability is thus 40% that cosmetic damage may occur but the likelihood is only 3 - 4% for larger damage. It will be observed that the investigations were based on changes between records of pre- and post-event inspections of properties. In post-event inspections the pre-event inspection record is used as a reference; a post-event inspection indicates, therefore, never a smaller number of cracks. For this reason it is very likely that there will be a number of additional entries in the post-event inspection record without an actual increase in the number of instances of damage. New instances of damage caused by ageing of the building have not been considered either. |
