This paper discusses the possible reasons that cause the karst land collapse hazard in the urban region of Tangshan city, China. Karst land collapse is a human induced geological hazard.Among the factors that count in collapse, only the factor of ground water state can be artificially controlled. Therefore, the remedial strategy in macroscopic sense lies on the optimal management of ground water: by optimal control of ground water state in the areas that have the danger of collapse, to make the possibility of collapse hazard reduce to its minimum in overall scale. A method of optimal ground water management for a non-linear multi-layer system with ground water confined- and unconfined interchange properties is presented. An applicable water programming plan for the purpose of collapse hazard reduction in Tangshan is proposed.
