摘　　要：以郑州-西安高速铁路为例,选择典型路段(潼关和华阴)地区特殊黄土,采集大量原状土样,进行大量室内试验和现场原位试验,如压缩试验和浸水试验,获得了一系列黄土力学参数。研究发现,该地区黄土浸水后变形较大,从而导致黄土沉降较为严重,该研究可为沿线湿陷性黄土地基处理方案进一步优化提供资料,同时也为其它地区同类黄土的设计与施工提供了参考。The paper takes Zhengzhou-Xi＇an high-speed railway for example, a large number of special loess samples in typical sections （Tongguan and Huayin） have been collected, based on the laboratory test and in situ test, such as compression test and immersion test, a series dynamic parameters of loess are provided. The result shows after loess immersion that deformation is large, so the loess settlement is serious. The study provides optimization information for collapsibility loess foundation along the line, and provides design and construction reference for other similar loess.
