滑坡后对施工情况、地表变化、土质情况进行了调查和稳定验算,结果表明:因淤泥未清净,淤泥深槽区和深槽过滤带产生圆弧滑动,施工合龙段产生复式滑动,连续三次滑动在地表对应形成小、中、大三条滑弧破裂带。提出了修复时保证稳定的措施,修复后数年一直保持的稳定。

After the landslide occurred,the construction process,change in the ground surface and soil properties were investigated and calculation was made to verify the stability of the revetments.The results of the investigations and calculations indicated that,circular slides developed in the deep mud trough and the filter zone owing to the un-cleaned mud in the trough and a composite slide occurred in the closure section of the revetments.The three successive landslides resulted in three rupture zones in the ground,which were identified as small,medium and large ruptures separately.Measure to ensure the stability of the revetments during the rehabilitation of the revetments waer proposed.
