摘要
Abstract
Full consideration of the static and dynamic load of 35 t axle load train generated at run time, the dy-namic characteristics study of subgrade structure which composed of different surface and bottom layer of subgrade filler and thickness was used to optimize the thickness of subgrade bed structure, based on strength con-trol method of subgrade filling. It is verified that when the bedding surface layer filling gravel gradation, thickness of top layer of subgrade bed is 0.7 m, bottom layer thickness is 2.1 m. When the surface layer of subgrade filler is A filling, the surface and bottom layer of subgrade bed thickness are 0.6 m and 2.4 m in scarce region;In a-bundant areas, they are 0.7 m and 2.1 m respectively.关键词
