Settlement Property of Subgrade Filled with Red Mudstone for Ballastless Track of High-Speed Railway
As a special material, red mudstone shows different engineering mechanical properties in practical application compared with the general subgrade fillers. Combining with a test section of subgrade in one passenger dedicated line, this contribution studied the settlement property of red mudstone. Firstly, this contribution grasped some physical and mechanical properties of red mudstone and its improvement through laboratory experiments. Secondly, in order to obtain the settlement datas of subgrade filled with this special filler, this contribution conducted centrifugal model tests, and also measured the field settlement on the test section. To further research this topic, the two types of tests mentioned above were simulated separately by applying finite element analysis software. Based on the results of all tests, this contribution analyzed the settlement property of subgrade in different stages, and concluded that both red mudstone and its improvement can meet the demands of ballastless track subgrade.
