Xiaolangdi Dam in China

Xiaolangdi inclined core rockfill dam is the highest earth core rockfill dam constructed in China, with the dam height of 160m. The project is located at the main stream of Yellow River and it has multiple functions. As its unique position in regulating Yellow River, specific high sediment flow, complex geological conditions, rigor requirements of reservoir operation and the huge engineering scale, it is considered as the most complicated and challenging project in the world. The construction of the project has applied a series of new technologies, which include: the construction of concrete diaphragm wall in deep foundation (81.9m), prevent sediment block at intakes of high sediment flow, large span underground structure excavation, stabilization of the intake and outlet of the left bank large scale tunnels and caverns, etc. Incorporation of new technologies and materials culminated in completion ahead of schedule, excellent quality and cost saving. After being put into operation, Xiaolangdi project has played an important role of restoring the ecological function of the river channel. Up to now, the project has been in stable and normal operation, resulting in remarkable social, ecological and economic benefits.

The project is owned by Xiaolangdi Dam Project Construction and Management Bureau.
