According to Zhengzhou-Xi'an high speed railway projects,conducted a 25m diameter im-mersion test in typical section(Tongguan and Huayin)of collapse loess which thickness is greater than 25m.the test lasted for 52d,at the same time,collected a large number of undisturbed soil sample,conducted laboratory tests,received a series of loess mechanical parameters.The research indicates that the loess in this area with large deformation after soaking,resulting in a severe sub-sidence of loess,it belongs self-weight collapsible loess,the study provides treatment and water-proof and drainage measures data for large thickness collapse loess subgrade along the railway,as well as providing theoretical support for the construction of similar loess in other areas.%结合郑州-西安高速铁路项目,在湿陷性黄土厚度大于25 m的典型路段(潼关和华阴)地区做了直径为25 m的浸水试验,试验历时52 d,同时采集大量原状土样,进行室内试验,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,属于自重湿陷性黄土,该研究可为沿线大厚度湿陷性黄土路基的处理及防排水措施提供资料,同时也为其它地区同类黄土的施工提供了理论支持。
