| 摘 要： | 水库蓄水后，粘土铺盖及下卧软粘土层将发生沉降，甚至裂缝。作者结合非稳定渗流计算，对软土层提出排水固结沉降过程的计算方法，并估算了是否发生裂缝的可能性。还对加快和减缓沉降的措施进行了讨论。

| Abstract: | Clay blanket and the underlying soft layer will be settling, even cracking, after storage of reservoir. A calculation method for settlement of soft earth layer in course of drainage consolidation is proposed; and the possibility of cracking is estimated. Finally, the measures to accelerate and decelerate the settlement of clay blanket are discussed. |

| Keywords: | seepage induced consolidation clay blanket settlement cracks |
