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

Centrifugal model tests were performed to investigate the effectiveness of settlement control using geogrid-reinforced pile-supported embankments for high-speed railways on collapsible loess. First, the acceptability of using remoulded loess to simulate the behaviour of undisturbed collapsible loess in wetting test was examined in centrifuge tests. Then, the settlement of geogrid-reinforced pile-supported embankments under different conditions …
