摘要
通过对道床受力变形机理的分析，考虑道床的流变力学特性对道床阻力的正确测试具有重要的意义．在大量的模型和实际轨道道床阻力的试验基础上，给出了道床流变力学特性对道床阻力测试结果的影响规律，指出了常用测试方法的欠缺之处，并就实际轨道的道床阻力的正确测试方法进行了研究．
By analyzing the mechanism of ballast deformation, the author considered it is important to consider the influence of rheology characteristic when testing the ballast resistance. On the basis of the large amount of model calculations and the practical testing of ballast resistance, the influence of ballast rheology characteristic on the testing of ballast resistance results were given. The deficiency of existing resistance testing method were pointed out, and the proper testing method of ballast resistance are discussed also.
