To treat the uneven settlement of ground by using cast in place pile underpinning is a practical and effective technique. 採用灌注樁托換技術處理地基的不均勻沉降是一種實用有效的方法。
The soft foundation dam section has two cracks in the Flying gorge key WR project main dam near Changshuitang because of uneven settlement influence. 飛來峽水利樞紐右岸長水塘附近的軟基壩段因受壩基的不均勻沉降影響，產生了兩條橫向裂縫。
Then the concepts, which are the nonlinear accumulation of foundation settlement and the settlement discrepancy between adjacent foundations, are put forward. 進而提出了基礎沉降值非線性累積與相鄰基礎間沉降差非線性累積的概念。
