The 2.5D finite/infinite element approach is adopted to study.wave propagation prob.ems caused b. underground moving trains. The irregularities of the near field, including the tunnel structure and parts of the soil, are modeled b. the finite elements, and the wave propagation properties of the far field extending to infinity.are modeled b. the infinite elements. One particular feature of the 2.5D approach is that it enab.es the computation of the three-dimensional response of the half-space, taking into account the load-moving effect, using only.a two-dimensional profile. Although the 2.5D finite/infinite element approach shows a great advantage in study.ng the wave propagation caused b. moving trains, attention should b. given to the calculation aspects, such as the rules for mesh estab.ishment, in order to avoid producing inaccurate or erroneous results. In this paper, some essential points for consideration in analy.is are highlighted, along with techniques to enhance the speed of the calculations. All these ob.ervations should prove useful in making the 2.5D finite/infinite element approach an effective one.
