Abstract:In recent years, significant progress has been made in monitoring and control of land subsidence in Shandong province. A fourgrid land subsidence monitoring system has been primarily established based on the secondclass alignment, Global Positioning System (GPS), bedrock stratification and groundwater monitoring. It is showed that land subsidence in Shandong province is mainly located in Guangrao county of Dongying city, Boxing county of Binzhou city and Chiping county of Liaocheng city. The sedimentation rate shows an accelerated trend. A series of geological environmental problems, such as subsidence of buildings, cracking of houses, and damage to underground pipelines have been caused.
