风积沙路基填筑料的物理改良研究

On the Physical Improvement of Aeolian Sand Roadbed

近年来,随着铁路建设的跨越式发展,部分铁路已深入到沙漠地区。但是,由于自然条件的限制,沙漠地区的路基填料的各项指标往往不能满足施工的需要,这就需要设计人员和建设者们在不利的环境下,寻找一种可以有效利用的新途径风积沙填筑路基。结合包西铁路的施工实践,对风积沙路基的物理改良施工进行了研究。

In recent years, as the railway construction develops dramatically, some railways reaches the desert areas. However, due to the limits of natural conditions, the index of roadbed filler in these areas cant always meet the construction requirements, which demands designers and constructors to look for an effective way for the aeolian sand filling roadbed under such adverse environment. Combined with the construction practice in Baotou-Xi＇ an railway, this paper studies on the physical improvement of aeolian sand roadbed.
