分析了唐山市城市岩溶地面塌陷灾害产生的原因，探讨了岩溶塌陷宏观减灾对策，通过优化开采地下水资源的管理方案来调整塌陷危险区中的地下水流场，使之形成最不利于发生塌陷的地下水状态，以达到在宏观上产生岩溶塌陷灾害可能性最小的目标。针对具有承压－无压水特征的非线性多含水层系统提出了水资源管理的分体模型方法和双重迭代求解技术。以岩溶塌陷宏观减灾为目的，提出了优化控制地下水流场的水资源管理方案，为唐山市城市规划提供了科学依据
This paper analyzes the causes of urban karst collapse in Tangshan City and discusses the macro-mitigation measures for karst collapse and adjusts the groundwater flow field in the collapse danger zone by optimizing the management plan of groundwater resources so that the most unfavorable groundwater collapse occurs State, in order to achieve the goal of generating the karst collapse in macro-hazard the least. Aiming at nonlinear multi-aquifer system with pressure-pressure-free water features, a split-model method and dual iterative solution of water resources management are proposed. With the purpose of macro-hazard reduction of karst collapse, a water resource management plan for optimizing groundwater flow control is proposed, which provides a scientific basis for urban planning of Tangshan
