摘要
戈壁地区的路基填料以粗颗粒、低含水量为主要特点,国内外关于戈壁地区填料用于高速铁路路基的研究很少。为给兰新高速铁路第二双线的修建提供技术支持,通过试验段柴窝堡工点的现场试验,分析了填料的性质,提出了戈壁地区高速铁路路基填料碾压工艺等一整套的填筑方法以及施工中应注意的问题。
Subgrade filling of Gobi area is mainly of coarse-grained soil with low water content.There is littleresearch on the filling used for high-speed railway subgrade in Gobi area at home and abroad.In order to provide technical support for construction of the second double-track line of Lanzhou-Xinjiang High-speed Railway,through site test on Chaiwobao Construction Point in experimental section,this paper analyzes the properties of filling and puts forward a complete set of filling method including subgrade filling compaction process for high-speed railway in Gobi area and the matters that shall be paid attention to during construction.
