摘　　要：介绍了汉沽污水库现场试验工程采用环保疏浚联合土工管袋的方式,对底泥进行清淤和脱水减容的工程实例,主要内容包括环保疏浚设计、脱水减容场地准备、土工管袋选型、土工管袋充填、絮凝剂投加等。通过对本工程的设计和全过程跟踪实践,摸索出环保疏浚联合土工管袋用于湖库底泥脱水减容的设计参数和操作流程,为今后规模化应用奠定了基础。The engineering case of using environment-friendly dredging with geotextile tubes for dredging, dewatering and volume reduction of sediments in Hangu Sewage Reservoir is introduced. It mainly includes design of environment-friendly dredging, preparation of dewatering and volume reduction site, selection of the geotextile tubes, filling of geotextile tubes, dosing of the flocculant and so on. Through the design and whole process practice of this engineering, the design parameters and process of environment-friendly dredging with geotextile tubes for dewatering and volume reduction of sediments in lake and reservoir are found to lay the foundation for its large-scale application in the future.
