沉降区 depression area
depressed area
- 隆起区多属高水平应力区,沉降区多属低水平应力区。
The horizontal stress is high in the uplift and low in the subsidence areas. - 这些沉降区多数都是以城市为中心,互相连成一片,下沉速度有逐渐加快的趋势。
Most of the descending areas are centered in cities, connecting each other, and the descending rate shows an accelerating tendency. - 当这种不均匀变形程度足以使土体连续性破坏时,则地裂缝便在沉降区应力集中的部位发生。
When the deformation caused by the inhomogeneous subsidence accumulates to the critical state of the soil, ground fissures will occur in the stress concentration positions.
