This may be due to the settlement of foundations or to a differential temperature movement of supporting piers. 这种运动可以是由于基础沉降或由于支墩因不同温度变化而产生。
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。
