This study overviews the development history, current
situation, impact, and hazards of land subsidence and ground fissure
disasters in the Beijing Plain (BP) and focuses on the disaster distribution
and features of disaster-causing mechanisms. Currently, the BP is still in a
rapid developmental stage of land subsidence. The development and
distribution of land subsidence are affected by various factors including
the thickness of Quaternary compressible clay, groundwater overexploitation,
and the rapid development of urban construction. The causes of ground
fissures in the BP are complex and diverse, with evidence of structure
fissures, non-structure fissures, and mixed genesis fissures. Investigations
of the Gaoliying ground fissure have shown that this fissure has evidence of
fracture activity, with vertical deformation that is more significant than
horizontal deformation. Furthermore, this ground fissure has characteristics
of inter-annual periodicity and annual jumping. The land subsidence and
ground fissures are all under structural control and impact each other, and
more severe hazards may be induced under the superimposition of these two
types of disasters. Effective measures and suggestions for disaster
prevention and control are recommended on the basis of this study. |
