“裂土”一词,在我国铁路工程界已被广泛引用和在规范中定名。但笔者认为,不同地区的裂土,在不同程度上确实存在有裂隙性,膨胀性以及因先期国结而引起的其他性质。但是随着地区的不同,裂土的这几种性质所表现的程度也有着明显的差别。也就是说,在某些地区,裂土的性质主要表现为裂隙性,其工程影响也受到裂隙(及其组合)的强烈控制;而 The term “cracked earth” has been widely quoted and named in the specification in the railway engineering sector in China. However, the author believes that cracks in different regions do exist to varying degrees in terms of fissures, swellability, and other properties that are caused by previous national conditions. However, with the different regions, there are obvious differences in the extent of these properties of ripping. In other words, in some areas, the nature of rifts is mainly fissured, and its engineering impact is also strongly controlled by fissures (and their combinations);
