| Abstract: | Dazhun-Shenchi railway is a newly-built ten-thousand tons heavy haul electrified railway across large collapsible loess areas, where serious loess collapsibility is found. The paper, based on the characteristics of the loess foundation and the collapse settlement calculation and analysis, selects the suitable reinforcement method of the collapsible loess founda-tion, carries out detailed analysis and calculation, and puts forward the quality inspection requirements to ensure the stabil-ity and reliability of this heavy haul railway roadbed engineering. |
