Man-Induced Land Subsidence, Reviews in Engineering Geology Volume VI [Editor Thomas L. Holzer] on *FREE* shipping on qualifying offers. Organic soil subsidence occurs mainly with drainage and development of peat for agriculture. Subsidence occurs either from densification (loss of buoyancy, shrinkage, and compaction) or from actual loss of mass (biological oxidation, burning, hydrolysis and leaching, erosion, and mining). Densification usully occurs soon after drainage is established. Subsidence in surface mining areas is caused by compaction of rehandled overburden material (spoil), dewatering of aquifers near surface mines, and (or) stress and strain readjustments. Depressions (troughs), cracks, and pits (sinkholes) can occur under either underground or surface mining procedures.

Ground failures, ranging from long tension cracks or fissures to surface faults, are caused by man-induced water-level declines in more than 14 areas in the contiguous United States. These failures are associated with land subsidence caused by compaction of underlying unconsolidated sediment. This book brings forward the concept of the geology-environmental capacity of ground buildings. It quantifies the geology-environmental capacity of ground buildings by analyzing the main factors of land subsidence and setting up the evaluation system. In this paper, the characteristics, formation conditions and influence factors of land subsidence in Daxing new town were described. Using Modflow software, land subsidence calculation model was established, and the land subsidence trends were predicted, which provides basis for the construction, planning and land subsidence control of the new. Abstract. Subsidence induced by underground extraction is a class of anthropogenic land subsidence that principally is caused by the withdrawal of subsurface fluids (groundwater, oil, .
In this section, the different types of land subsidence are discussed. They are separated into natural causes and man-induced causes. The natural causes are mainly geological causes, such as formations of caves, sinkholes, and karst topography. The man-induced causes are mainly mining or fluid withdrawal (groundwater and/or oil or gas).
