摘　　要：2009年,淮河三河闸下游引河左岸K0＋590-0＋710段浆砌块石护坡表面出现裂缝,局部鼓胀,堤顶道路沉陷,管理单位采取了应急处置措施,进行地质钻探和边坡稳定性分析,并认为主要由膨胀土引起。采取了改良土体性质、阻滑、排水等综合治理措施,2011-2015年,通过对该段护坡的跟踪检查、观测,该段护坡顶、坡高程保持完工时的数值,排水系统运行正常,未出现新的失稳迹象,取得了预期效果。In 2009, the cracks and deformation on grouted rubble revetment levee of downstream Sanhe gate in Hahe River caused the road subsidence on top of the dam. Emergency response measures had carried out. After investigation and study on geological and the slope stability, the result showed that the damage mainly caused by expansive soil. Therefore, a comprehensive treatment measure was implemented, including improved soil quality,slipping resistance, and drainage system. This section was inspected in 2015, slope deformation did not occur again,which further proved the countermeasures were effective and functional.
