ABSTRACT
Economic progress observed in recent years triggered the need for the expansion of transportation infrastructure as well as the growing interest in the land located in close proximity to already existing buildings. Erecting new buildings within compact housing imposes on the investors the obligation to create a particular amount of parking places. The expansion of road and motorway network requires developing the areas with complex geology, whose use was previously economically unjustified. The above mentioned aspects cause the need for technologies that make it possible to take maximum advantage of small free city spaces or to found engineering structures almost in any possible geo-hydrological conditions. Most of the available soil improvement techniques are accompanied with noise and vibrations. When the amplitudes of vibrations go beyond the levels defined as safe in the code of practice, or when the vibrations become exceedingly perceptible by the humans, it is however possible to correct the technology of the works’ execution. This work presents selected aspects of the active designing, using the investigation of the impact of vibrations that occur during the soil improvement and piling works, on adjacent engineering structures.
