To treat the uneven settlement of ground by using cast in place pile underpinning is a practical and effective technique. 采用灌注桩托换技术处理地基的不均匀沉降是一种实用有效的方法。
The soft foundation dam section has two cracks in the Flying gorge key WR project main dam near Changshuitang because of uneven settlement influence. 飞来峡水利枢纽右岸长水塘附近的软基坝段因受坝基的不均匀沉降影响，产生了两条横向裂缝。
Then the concepts, which are the nonlinear accumulation of foundation settlement and the settlement discrepancy between adjacent foundations, are put forward. 进而提出了基础沉降值非线性累积与相邻基础间沉降差非线性累积的概念。
