Karst collapse is a common geological disaster, and groundwater level is the main influencing factor of karst collapse in Linyi City. This article uses the established groundwater flow model to propose a method for controlling karst collapse: to make the karst water level not lower than the control level. Based on this method, three different groundwater extraction schemes were designed in the study area, and calculation analysis was performed in conjunction with water level control points. The results show that in the future, the amount of karst water exploitation in the urban area of Linyi City will be reduced by 11.65×104m3/d compared with the current situation, The reduced groundwater volume will be solved by the surface water project of the Andi reservoir in Linyi City, which can control the danger of karst collapse.
