Mechanism and Prevention of Urban Land Subsidence

Article Preview

This paper introduces the hazards of urban land subsidence which caused by excessive extraction of groundwater, the construction of high-rise buildings and excavation, then analyses their mechanisms. It is considered that the essence of land subsidence is due to the soil compaction caused by effective stress augment and the soil loss caused by excavation. Through further analysis of current works, we suggest that regional differences in geological conditions, building loads, repeated action of groundwater withdrawal and recharge, and meso-mechanism of soil particles should be considered when establishing land subsidence model.
