随着我国经济发展速度的加快,我国的铁路开始进入高速建设阶段。通常在我国的铁路工程建设过程中,对于铁路路基的设计标准都较低,所以在施工中对质量的控制也不严格,这样铁路在运营后,由于长期在列车的碾压及荷载下,铁路线路路基病害频繁发生。特别是在我国铁路连续不断的提速过程中,在重载及高速下,原有的路基承载力设计偏小,在高速下所引起的较大应力下,也加重了线路路基病害的产生,从而对列车的运行安全性造成一定的影响。本文分析铁路线路路基病害类型及原因,并进一步对如何治理铁路线路路基病害进行了具体的阐述。
With the acceleration of the economic development in our country, our country’s railway has entered a stage of high-speed construction. Usually in China’s railway construction process, the design criteria for the railway subgrade are low, so in the construction of the quality control is not strict, so that after the railway operation, due to long-term train rolling and loading, the railway Roadbed diseases occur frequently. Especially in the continuous speed-raising process of China’s railway, under the condition of heavy load and high speed, the design of bearing capacity of existing subgrade is too small, under the high stress caused by high speed, it also aggravates the generation of roadbed disease, The operation of the train safety has a certain impact. This article analyzes the types and causes of railway roadbed disease and further elaborates on how to treat the railway roadbed disease.
