The Analysis on Distribution Characteristics and Influence Factors of Ground Collapse in Nanjing City
摘要
Abstract
With the accelerated urbanization process,ground collapse problem,one of the major geological disasters in Nanjing City,becoming increasingly prominent,is a serious threat to urban construction and development,therefore the development of distribution characteristics of ground collapse and its countermeasures is of great practical significance.We divide the ground collapse of Nanjing into three major types such as karst collapse,goaf collapse,and project collapse.The main collapse type is the karst collapse and goaf collapse in the past century.In recent years,with the expansion of urban infrastructure construction,the rate and destructive of project collapse is increasing.The ground collapse is mainly due to excessively pumping groundwater,mining or heavy rains,artificial loading,artificial vibration.Only if Nanjing government strictly limits to develop of groundwater and mineral resources,and ascertain the condition of the geological environment.It can effectively control ground collapse.关键词
