| Abstract: | Zhengzhou-Xi'an passenger dedicated railway line is 350 kilometers per hour ballastless track; its allowable subgrade settlement should be less than 15 mm after completion of the subgrade. In order to meet the requirements, the relevant tests are carried out; and the collapsible loess subgrade treatment principles are determined. And the subgrade are treated successfully by using cement-soil compacted piles, long and short piles and embedding continuous pile-board structure. The achievement will be reference to the upcoming construction of Xi'an-Baoji passenger dedicated line, Baoji-Lanzhou passenger dedicated line, Xi'an-Chengdu passenger dedicated line. |
