黄河下游淤筑相对地下河的可行性技术

Feasible Techniques of Lower River Bed Formation Through Irrigating Sedimentation in Lower Reaches of Yellow River

本文简介了“结合引黄供水沉沙淤筑相对地下河的研究”中有关引水、沉沙、挖淤、输沙、淤筑和施工组织管理等方面的成套可行技术，包括输、沉沙渠（池）设计计算方法，沉挖方式和方法，淤筑施工机械的选型配套，泥沙输送技术以及淤筑技术等。各项技术紧密配合，针对性强，便于实施，基本可以满足在不打乱原有引黄灌排体系条件下，进行淤筑相对地下河规划、设计和施工的需要。

The paper summarizes feasible series techniques in the formation of lower river bed through irrigating sedimentation in lower reaches of Yellow River on some issues, i. e., water drawing, sedimentation,sediment digging out,sediment delivery,dyke construction through sedimentataion and operation,organization and management,and so on. These techniques include design and calculation method on sediment delivery,sediment silt channel and chamber,mathods for sediment digging out, machine sellection and forming a complete sets, sediment delivery techniques,and dyke building through sedimentation. As these techniques are cooperated very well,convenient for application,and possible to meet the demonds for lower river bed formation design and construction without influencing the existing Yellow River irrigation system.
