Abstract

In this paper, stress analyses in concrete sleeper has investigated by using results of the tests which have been done in main line of railway track. In these tests, special concrete sleeper (B70) installed in railway track. Five load cells fixed inside of the sleeper during constructing of that. After replacing this special sleeper with ordinary sleeper, and tamping in railway track, a train with certain axle load passed through that point of track. Forces on sleeper are analyzed (output of measurement). The results show that B70 concrete sleepers are designed well for tamped and no tamped cases. In the both cases, the stresses in sleeper cross sections are in allowed range. Also, the results show that the track without DTS operation (after replacing of the sleeper) decreases share of sleeper bearing and increases forces on adjacent sleepers. These forces together with dynamic effect of rail-sleeper interaction will accelerate sleeper's deterioration. This means that after replacing failured sleepers, the sufficient length of track must be operated by DTS and Tamping machines.
