Abstract


Land subsidence as one of the environmental and geological disasters , has serious impact on the living environment of mankind , and caused huge economic losses . Factors of land subsidence human master , to help people to a profound understanding of the causes of land subsidence mechanism , to further determine the land subsidence human master indicators provide theoretical guidance and scientific basis . Based on the latest understanding of land subsidence is groundwater extraction and building load dual role of environmental geological disasters , this paper focuses on two human master factors of land subsidence - groundwater mining and construction loads cause vertical crustal deformation mechanism . Land subsidence caused by groundwater exploitation instance analysis found that the critical water level the master indicator of the control of land subsidence and maximize the development and utilization of groundwater resources , and given the relatively simple and accurate critical level determination . Ground subsidence , construction loads caused by indoor simulation test prospective exploratory study . Vertical elastic deformation under the assumption derived surface load increase caused by ground subsidence mechanism expressions . The results show that : the surface load increase can indeed cause land subsidence , but can also cause a rise in ground water level ; loads, the linear relationship between land subsidence and groundwater level , and the linear correlation coefficient the skeleton flexible interpretation of the aquifer water coefficient ; according to the cause the ground settlement mechanism of expression as well as the load effect model test shows that land subsidence caused by increased surface load can be expected and calculated surface load increases .
