Abstract
The article discusses the features of monitoring the dynamic impact, processes of vibration driving and vibro-extraction of sheet piles in conditions of a large thickness of weak, water-saturated soils. Many years of development experience has shown that, with respect to reliability, it is not enough to carry out analysis with calculations only in the preparation of loadings. The generated vibration field has a negative impact on the structures located near. The analysis of the existing normative documents on the assessment of the dynamic impact on the construction site is given. It is noted that modern monitoring techniques make it possible to assess the impact of the surface Rayleigh wave, however, the development of additional deformations of buildings is caused by deep, body waves that affect the weak underlying soils of the base. Based on the results of numerical modeling and analysis of experimental studies of other authors, an alternative scheme for installing vibration sensors is proposed for assessing the dynamic impact during immersion and extraction of sheet piles.
