| مستخلص: | Xuzhou urban region has been seriously threatened by the geological hazards, such as karst collapse. Several collapses that had widely occurred were distributed in the ancient Yellow River Fault zone. Obviously, they were zonal and being controlled by the river fault zone. The karst was developing well in the fault zone and it connected the Cambrian and the Ordovician aquifer which made karst groundwater was very rich. The long-term pumping groundwater made the level up and down around the bedrock surface and the sandy soil covered directly on the karst aquifer which deposited with the form of paleochannels had changed. That is the main reason for the occurrence of karst collapse. [ABSTRACT FROM AUTHOR] |
