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 in the Gobi area is mainly characterized by coarse particles and low water content. Few studies have been done on the application of high-speed railway subgrade at home and abroad. In order to provide technical support for the construction of the second lane of Lan-Xin high-speed railway, the properties of the packing were analyzed through the field tests at the experimental site of Chaiwopu, and a complete set of filling technology for subgrade filling of high-speed railway in the Gobi region Construction methods and construction should pay attention to the problem.
