摘要
Abstract
The subgrade stress and settlement modes are established through finite element analysis soft-ware ANSYS. The material parameters of subgrade are selected based on investigation, which are entered into the model with the selection of various filling height and degree of compaction. Then the maximum vertical compressive stress, the maximum vertical shear stress and the maximum horizontal shear stress of subgrade with different degree of compaction as well as the settlement of the center and edges of coal gangue subgrade are calculated. The impact of the degree of compaction on the stress and settlement of coal gangue subgrade are analyzed, and the recommended value of the degree of compaction of coal gangue subgrade is proposed.关键词
