The dam body and foundation seepage is one of the important points in design parameters. This index is related to the permeability. Therefore permeability is one of the basic parameter in design grout curtain, prevent water escape from foundation and avoid ...

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 ...

The basis of the design of earth and rockfill dams is focused on ensuring the stability of the structure under a set of conditions expected to occur during its life. Combined mechanical and hydraulic conditions must be considered since pore pressures develop ...

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>No earthquake has caused failure or severe damage to any rockfill dams with bodies of well-compacted rock materials. It is important to estimate the damage grade quantitatively in order to evaluate a seismic performance of a dam against a large earthquake. ...

This paper discusses some of the problems encountered with water ingress on the 72km of tunnels on this project. Grouting is always a significant portion of dam projects and with the quantities of water expected in the tunnels, was also going to be an important ...

<p>The Guidelines for the Construction of Earth-Fill Dams detail the specifications for the construction of earth-fill dams, and outline the precautions and methods which should be employed in order to obtain the soundest possible structure. These guidelines ...

<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 ...
