Experimental analysis on settlement controlling of geogrid-reinforced pile-raft-supported embankments in high-speed railway

Centrifugal model tests were performed to investigate the effectiveness of settlement control using geogrid-reinforced pile-raft-supported embankments for high-speed railways on collapsible loess. Firstly, the acceptability of using remolded loess to simulate the behavior of undisturbed collapsible loess in wetting test was examined in centrifugal tests. The settlement of geogrid-reinforced pile-raft-supported embankments under different …
