“…The article [3] substantiates the influence of the initial tunnel design on the level of soil vibration during the operation of the underground line in the future. This is important because the construction of the tunnel leads to soil disturbance, which indicates a high level of soil deformation near the tunnel.…”

The article is devoted to a topical issue - the development of a method of densification of the base of the underground interstation tunnel to prevent further intensive subsidence of tunnel structures. Based on computer-mathematical modeling, the work establishes experimental dependence between the angle of inclination of jet grouting piles and the amount of subsidence of the distribution plate on which the tunnel structures rest upon. Inspection of the technical condition and analysis of defects in a comprehensive comparison with subsidence graphs allowed us to identify the main typical deformations during subsidence of a shallow tunnel built from blocks of a solid-section frame, namely their characteristic features, geometric parameters and placement points.

“…c = 135 m/s × 50% = 68 m/s. Often, the frequency of interest for the perception of the ground-borne vibration lies within the range 𝑓 ̅ = [1-80] Hzsee [230][231][232]. However, since frequencies close to this limit might also contribute to the response, the limit is extended to 𝑓 ̅ = [0.5-150] Hz (range similar to the used in [54,59]), corresponding to a wavelength range of λ = [0.45-135]m.

Continuous wave barriers are mitigation measures to reduce vibrations induced by railway traffic which have been well studied in technical literature. Nevertheless, there are not many studies about discontinuous concrete wave barriers. By this reason, in this paper continuous and discontinuous concrete wave barriers are studied and compared. With this objective, two theoretical cases with discontinuous barriers have been analysed and the results have been compared with those from both continuous barriers and without barriers cases. The study has been carried out with a dynamic numerical 3D FEM model formulated in the space/time domain, which has previously been validated by authors on the Lisbon-Oporto (Portugal) railway line. The numerical results show the discontinuous barriers with a small separation between axles (less than twice the thickness of the continuous barrier) are an efficient measure in the reduction of vibrations, reaching values of insertion loss of up to 13 dB. So, these could be a very interesting alternative to continuous barriers, in order to conjugate a somewhat lower level of reduction of vibration at a considerable lower cost.
