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.
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。
2
And the relativity of ground particulate emission factor and the concentration of resuspended particulate in total suspended particulate (TSP) was studied.
同时进行了地面起尘因子与城市空气总悬浮颗粒物(TSP)中扬尘浓度的相关性研究。
3
Then, the concentration under different wind diffusion condition are analysized by using ground pollution mode so that the ratio of contribution to the total pollution limit is obtained.
