The latest progress of research on land subsidence abroad and its inspiration to China

Land subsidence not only has negative effects on the development of social economy but also threatens the safety of human life. For promoting the further development of the work of land subsidence prevention and control, in this paper, the authors aim to study the international advanced land subsidence work ideas, methods, technologies and management policies. This paper briefly reviewed communication achievements of the symposia and published papers in recent years, which can provide guidance for the work of land subsidence prevention and control in China. The strong points and weaknesses of land subsidence prevention work in China were analyzed by comparing with work in foreign countries in such aspects as monitoring methods, monitoring systems, measured data accuracy, mechanism, and governing policies. The work of land subsidence prevention and control in China still has a long way to go in terms of land subsidence monitoring, mechanism study and improvement of relevant laws and regulations.
