铁路路基及各种建筑物基础一般都位于第四纪地层土,因此第四纪地层及其有关的物理地质现象如岩堆、滑坡、流石流泥、沙漠、喀斯特、盐渍土、永久冻土层、沿海淤积及地震等对铁路建筑物地基来说,关系极为重大。研究这些现象,了解拟修筑工程地区的地质条件,掌握其发生发展的规律,从而拟出正确的工程措施,便可使工程建设顺利进行,否则必将导致困难,甚至遭到严重的损失,有关这一方面的例子是不胜枚举的。解放以后,由于大规模铁路线的勘测和兴建,在我国的各种不同自然地理区域中,所遇到的
Quarrying of Quaternary strata and related physical and geological phenomena such as rock piles, landslides, liquefied mud, deserts, karsts, saline soils, permafrost Layer, coastal siltation and earthquake on the railway infrastructure, the relationship is extremely important. Studying these phenomena, understanding the geological conditions of the area to be constructed and the laws governing their occurrence and development, so as to draw up the correct engineering measures will enable the construction to proceed smoothly. Otherwise, it will surely cause difficulties and even serious losses. The examples in this regard are endless. After the liberation, due to the survey and construction of large-scale railway lines, in various natural geographical regions of our country,
