北方软土路基在冬季冻起,在春融时期翻浆冒泥,造成线路偏跨下沉外挤,边坡排水沟坍塌等病害,威胁行车安全,文章结合工程实例提出采用柔性钻对道床下软土进行加固的方案,可在不中断行车条件下进行,对既有线具有实用性,加固效果较好。 The soft soil subgrade in the north is frozen in winter and turns into mud in the spring thawing period, causing the line to cross and sink and squeeze out, the slope gutter collapses and other diseases threaten the traffic safety. According to engineering examples, Soil reinforcement programs, can be carried out without interruption of traffic conditions, the existing line has practicality, better reinforcement effect.
