Abstract
The main purpose of this research was to determine the effect of the distance of the trains on the amount of consolidation settlement. By modeling the load equivalent to the simultaneous passage of two trains on the high-speed railway in "Plaxis-2D" software, and comparing the values ​​of total settlement resulting from continuous loading for fifty years, as well as non-continuous loading for ten days, it was observed the amount of consolidation settlement, with time Between crossings, there is a reverse ratio; Also, changes in pore water pressure and its reduction process also lasted longer in loading with longer intervals. Because the parameters for determining the consolidation settlement depend on the characteristics of soils (permeability coefficient K, modulus of elasticity E, Poisson's coefficient ν); If the overall calculation meeting for the service period of the railway line exceeds the permitted range of regulations; Provisions should be made to improve the soil characteristics of the railway track and strengthen it.
The compressibility of clay, as a railway track bed, is one of the most important issues in design. In the high-speed railway, due to the high speed and the short time of the train, which consequently changes the intensity of the load, it can be ignored and the loading can be considered statically; The passing distances of trains have a significant contribution in the clay behavior; Because in fact, this time is an opportunity for part of the deformation of the bed clay to return to its previous state.
