摘要
南昆铁路K595+760^+812段路基坍滑,路肩向外挤出,严重影响行车安全。在分析坍滑原因的基础上,阐述了现场整治措施:首先采用临时措施控制坍滑继续发展,然后采取设置支挡结构、截断上游渗水的处理措施根治路堤坍滑。整治工程取得良好效果,保证了南昆铁路的行车安全。
There happened subgrade slump in the Section K595 ＋760 - ＋ 812 of Nanning-Kunming Railway,leading to the shoulder squeezed outward and affecting the running safety seriously. This paper, based on the analysis of slump causes, decribed the measures for field control, including temporary measures used firstly to control the continuous development of slump, then retaining structure set and water seepage in the upper reaches cut off to bring it under permanent control. These measures had good result and guaranteed the safety on the Railway.
