| description | <p>Land subsidence caused by large-scale engineering
construction may damage the surrounding infrastructures and cause huge
economic losses in inner-city environments. In this study, we used PS-InSAR
technology on 68 TerraSAR-X images to acquire deformation in the Beijing
Plain between February 2010 and December 2018. Then, we calculated the
additional stress derived from building loads using the method proposed by
Boussinesq in the Central Business District (CBD). We found that the depth
of influence of additional stresses induced by building loads was 80 m and
that spatial distribution pattern of the land subsidence rate agreed well
with the additional stress. We found that the influence range of ground
subsidence caused by metro construction is 200 m at Ciqikou station by
analyzing the subsidence rate profile perpendicular to subway line No. 7 and
that the maximum land subsidence rate is 23.2 mm yr<span class="inline-formula"><sup>−1</sup></span>. Time series
analysis of PS around Ciqikou station shows that land subsidence caused by
excavation activities mainly occurs in the period of metro construction.
Ground deformation rate decreases gradually after 372 d of subway
operation. The results of both cases show that large-scale engineering
construction will lead to significant land subsidence which should be
considered in future urbanization.</p> |
