Practical aspects of applying the principles of environmental protection against vibrations in the process of preparation and implementation of railway investment

Abstract

Both in the case of reconstruction (modernization) of existing railway lines and construction of new ones - it is necessary to take into account the impact of these investments on the environment. One of such influences are vibrations caused by train passing. Vibrations transmitted to the building through the ground have an impact on: the construction of the buildings, the people staying in them and the vibration-sensitive devices if they are in the building. These receipts are not always sufficiently included in environmental documents. This issue often raises a number of doubts. The paper presents the basis for the assessment of the vibration effects mentioned above. Then the following is presented: an algorithm to take into account these influences at the stage of preparation and design and implementation of railway investments, the problem of determining the extent of zones of dynamic impact from the operation of the railway line, indications regarding the typing of representative buildings, rules for performing pre-realization tests of the impact of vibrations on representative buildings and on people in these buildings (dynamic background measurements) and the principles of post-implementation measurements, the problem of forecasting the impact of vibrations on representative buildings and on people in these buildings. It also presents some remarks about problems of protection of neighboring buildings against vibrations from construction works related to the implementation of investments.
