随着中国科技的发达与进步,像高速铁路这种具有速度快、能耗低、运价低廉、污染少且占地少,运营安全的交通工具在全国范围内已经广泛被大家所认可,所以铁路的修建也在全国广泛的开展。由于我国地大物博,各个地方的土质差异性大,能直接用于铁路路基基床的填料相对是比较贫乏的,所以铁路路基基床填料改良试验成了势在必行。 With the advancement and progress of science and technology in China, such transport facilities as high-speed railway with high speed, low energy consumption, low freight rate, less pollution, less land occupation and safe operation have been widely recognized by all over the country. Therefore, The construction of the railway is also carried out extensively throughout the country. Because of the vast territory in our country, the soil quality in different places is quite different. The filler that can be used directly in the subgrade bed of railway subgrade is relatively poor. Therefore, it is imperative to improve the subgrade bed filling test of railway subgrade.
