This report compares two different dam types (Roller Compacted Concrete Dam and Concrete Face Rock-fill Dam) in order to help the decision making when choosing what dam type to build in Panama, where Vattenfall is involved in a joint venture to build a dam ...

The 182 m high concrete face rockfill dam (CFRD) is one of the main components of the Nam Ngum 2 (NN2) hydropower scheme in Lao PDR. Construction of the dam was essentially completed in March 2010 and reservoir impounding commenced subsequently. This paper ...

Nam Ngum 2 dam, a large concrete face rockfill dam (CFRD) of 182 m height, is under construction and impounding is scheduled to start at beginning of April 2010. The dam is situated in a narrow valley and founded on sedimentary rock of variable strength. Dam ...

<p>A numerical procedure for the preliminary estimation of the earthquake-induced settlement of concrete face rockfill dams is presented. The method is based on a simple constitutive model that accounts for the key features of the behavior of coarse grained ...

Many high concrete face rockfill dams (CFRD) have been built in different countries. Russian engineers have been studying the world experience of CFRD design and possibility CFRD construction in the high seismicity regions of Russia. The report considers the ...

Roller compacted concrete (RCC) dams and concrete-faced rockfill (CFR) dams have become viable alternatives to large conventional concrete and embankment dams because of their considerable potential economic benefits. These new dams create also new risks, ...

The contact behavior between concrete face slab and dam body is important to the safety of concrete-faced rockfill dams. The deficient of dam body and the separation of concrete slab from cushion layer during construction and in operation are the main concerns. ...
