| 摘 要： | 坍岸路基是铁路工程中常见的不良地质之一。铁路在沿河沿江、靠近水库地段，由于水位的涨跌，都容易形成坍岸路基。通过襄渝线新覃家坝至三汇镇区间DK607+240～+320坍岸路基的特征、形成机理和稳定性的分析，采用桩基托梁和桩板墙复合结构对该区坍岸路基进行治理，治理效果明显。

| Abstract: | The changes of the bank-caving subgrade is one of the common unfavorable geology in railway engineering. As the water level, the railway sections along the river and close to the reservoir sites is easy to form a bank-caving subgrade. Though the analysis on the characteristic, formation mechanism and stability of the bank-caving subgrade between new Qinjiaba and Sanhui town （ DK607 ＋ 240 - DK607 ＋ 320 ） of Xiangfan Chongqing Railway, the pile foundation underpinning and the sheet-pile wall composite structure are used to treat the bank-caving subgrade, and the treatment result is outstanding. |
