THE STUDY OF THE MAIN CONTROL FACTORS CAUSING GROUND SUBSIDENCE IN ZIBO AREA

In recent years, the ground subsidence disaster of Zibo area is becoming increasingly serious, and is a hazard to engineering construction and personnel safety of life and property. The article focus on the main control factors and mechanisms which cause ground subsidence in Zibo area; it is based on the theory of structural geology, hydrogeology, engineering mechanics and so on. It is concluded that because of the high strength pumping groundwater in mining or living, the water tables are plummeting, so the soil of the surface loses the supporting force of groundwater, causing the ground above to cave in. The research result has the theoretical and practical significance to prevent and control ground subsidence of Zibo area.
