Discussion on the Frost Heave Characteristics of Coarse Particle Fillers for High Speed Railway Subgrade

高速铁路的施工和路基变形控制是影响轨道平整度和轨区骑行安全的主要因素。粗颗粒填充主要应用于高速铁路路基施工技术,高速铁路路基粗颗粒填料冻胀特性对高速铁路路基有着重要作用。因此,高速铁路路基粗颗粒填料冻胀是工程师高度重视的问题。论文通过对高速铁路路基粗颗粒填料冻胀特性室内试验分析,指出了高速铁路路基粗颗粒填料冻胀特性的监测结果,并从高速铁路路基粗颗粒填料冻胀性能和效果进行了研究。

The construction of high-speed railway and the deformation control of subgrade are the main factors that affect the smoothness of track and the safety of cycling in rail area. Coarse particle filling is mainly used in the construction technology of high-speed railway subgrade. The frost heave characteristics of coarse particle filling in high-speed railway subgrade play an important role in high-speed railway subgrade. Therefore,engineers attach great importance to frost heave of high speed railway subgrade coarse grain packing. Based on the laboratory test analysis of frost heave characteristics of coarse particle packing in high-speed railway subgrade, this paper points out the monitoring results of frost heave characteristics of coarse particle packing in high-speed railway subgrade, and studies the frost heave performance and effect of thick particle packing in high-speed railway subgrade.
