对不同渠段膨胀岩土渠坡产生滑坡的原因进行分析，提出了不同的处理措施：膨胀岩土换填层的滑坡，采取换填层后增设排水系统进行处理；结构面作用下的滑坡，通过边坡稳定计算后，采取清除结构面以上的土体后进行回填保护措施；浅层干湿循环导致的滑坡，在边坡整体稳定的前提下，清除滑坡体后，采取换填保护措施，开挖后要尽快进行换填处理，尽量减少暴露的时间。%The reasons for landslide of canal slope of expansive rock and soil in different canal sections were analyzed,and different treat-ment measures were taken. For the landslide of replacing filling layer,it should be done to add the drainage system after replacing the filling layer. For the landslide under the action of structural plane,we should first carry on the slope stability calculation,then clear the soil bodies above structural plane,finally adopt backfill protection measures. For the landslide induced by shallow alternation between drying and wet-ting,we should take protective replacement measures as soon as possible after removing the landslide bodies in the premise of slope stability, and reduce the exposure time as much as possible.
