常见铁路路基病害及路基加固技术分析

铁路路基是指承受列车及其轨道荷载的建筑结构,路基的质量深刻影响列车的安全运行。受地质因素、自然环境因素、列车荷载因素的影响,铁路路基容易出现老化、下沉等问题。在社会经济、交通和物流运输业的发展下,重载铁路得到了广泛应用,和一般铁路相比,重载铁路的行驶路程较远、承载的货物较重,得到了广泛应用,和一般铁路相比,这种类型的铁路更容易出现路基病害,且发生路基病害之后对社会发展影响更为深刻。为了能够更好地促进我国铁路运输事业发展,文章以重载铁路为研究对象,在阐述常见铁路路基病害的基础上,重点分析高压旋喷桩施工技术在重载铁路路基加固中的应用。

Railway subgrade refers to the construction structure which bears the load of train and its track. The quality of sub-grade has a profound impact on the safe operation of trains. Affected by geological factors, natural environment factors and train load factors, the railway roadbed is prone to aging, subsidence and other problems. With the development of social economy, transportation and logistics, heavy-haul railway has been widely used. Compared with the general railway, the heavy haul railway has a long dis-tance and heavy cargo, and has been widely used. Compared with the general railway, this type of railway is more prone to roadbed disease, and after the roadbed disease, the impact on social development is more profound. In order to better promote the develop-ment of railway transportation in China, this paper takes heavy haul railway as the research object, on the basis of expounding the common railway roadbed diseases. The application of high pressure rotary grouting pile construction technology in the reinforcement of heavy duty railway subgrade is analyzed emphatically.
