重载与高速是铁路发展的方向,轴重与速度的增加都会导致路基动应力的增加,使得路基状态进一步恶化。文章对我国现有重载路基存在的问题进行了分析,并针对重载路基病害,例如翻浆冒泥、路基下沉和路肩冲刷提出相应的整治对策。
Overloading and high speed are the direction of the development of the railway. The increase of shaft weight and speed will lead to the increase of the dynamic stress of the roadbed, which will further deteriorate the roadbed status. The article analyzes the existing problems of existing heavy subgrade in our country, and puts forward corresponding remediation countermeasures for heavy subgrade diseases, such as slopping, subsidence and shoulder scouring.
