国际铁路联盟研究试验所(ORE)D-141专题委员会,在英国铁路德比(Derly)试验室和波兰铁路铁道科学研究院进行了不同轴重对传统式道碴轨道下沉影响的模拟试验。在英国铁路德比(Derly)所做的试验,是在轨道质量、荷载次数、以及环境等相同条件下,测试轴重加大对轨道下沉的影响。在波兰铁路铁道科学研究院所做的模拟试验,是测试钢轨类型、轨枕类型、轴重、荷载次数等参数对轨道下沉的影响。
A D-141 thematic committee of the International Union of Railways Research Laboratory (ORE) conducted a simulation test of the effect of different axle weights on the sinking of a conventional ballast track at the British Railroad Derly Laboratory and the Polish Institute of Railways and Railways. The test done at Derly, the British railroad, was to test the effect of increased axle load on orbit sinking under the same conditions of orbital mass, load frequency, and environment. The simulation test carried out at the Polish Institute of Railway and Railways is to test the influence of the rail type, the type of sleeper, the axle load and the number of loads on the rail subsidence.
