There is a great need to develop rail networks over long distances and within cities as more sustainable transport options. However, noise and vibration are seen as a negative environmental consequence. Compared with airborne noise, the related problem of ground vibration is much more complex. The properties of the ground vary significantly from one location to another. There is no common assessment criterion or measurement quantity and no equivalent to the noise maps. Ground-borne vibration is transmitted into buildings and perceived either as feelable whole-body vibration or as low frequency noise; it can also affect sensitive equipment but it is generally at a level that is too low to cause structural or cosmetic damage to buildings. A review is given of evaluation criteria for both feelable vibration and ground-borne noise, empirical and numerical prediction methods, the main vehicle and track parameters that can affect the vibration levels and a range of possible mitigation methods.

“…In recent decades, research on the dynamic interaction of vehicle-rail bridges has increased and primarily focuses on the following aspects: (1) e dynamic response of trains in dangerous areas, such as road bridge transitions, curved bridges, and culvert transition zones [12][13][14][15][16][17][18][19]. (2) e dynamic performance of a train that passes through a bridge under external adverse influences, such as earthquake, wind and bridge skewness, or noise of composite bridge results [20][21][22][23][24][25][26][27].…”

Field tests and numerical simulations are combined in this paper. Cross-sectional dimension measurements, dynamic performance tests, and forced vibration tests were performed on the NO·40 beam bridge of the Xin-Tai Railway. By comparing the test results with the specifications, the current service status of the bridge was evaluated, and the basis for subsequent correction and verification models was provided. A dynamic coupled finite element model of the passenger-freight-cable-track-bridge was established considering the degree of bridge damage (0%∼50%) and the track irregularity, and the model simulation results for the Xin-Tai Railway NO·40 bridge were measured. The results are compared to verify the correctness of the model. The results show that the damage to the bridge will affect the vertical displacement response and the safety stability of the train. The vertical displacement response of the bridge midspan is twice that of the bridge performance. When the damage level of the bridge is 30%, the passenger and freight trains exceed the safety warning limit, which should cause concern.

“…Regarding the estimation of the vibrations of the target structure, measures were taken to reduce the target structural vibrations and noise 28,29 induced by traffic loads. Ulgen et al 30 studied the foundation design and vibration isolation of a high-precision instrument subjected to ground-borne vibrations. Thompson et al 31 discussed reducing railway-induced ground-borne vibration by using open trenches and soft-filled barriers.…”

This study established the transfer laws of vibration waves in a linear system under simple harmonic loading. Then, a method based on multipoint delivery in the frequency domain was proposed to predict the vibrations of historical timber buildings induced by traffic loads, in which the transfer function between two delivery points of different single frequencies is obtained. Finally, the vibration responses of the Feiyun pavilion induced by traffic loads were predicted and compared with experimental field test results. The results indicate that the predicted vibration responses and experimental field tests at the measurement point in the Feiyun pavilion correspond well in the concerned frequency bands and that the proposed prediction method can be used to predict the structural vibration responses under the influence of complex traffic loads.
