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 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 ...

<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 ...

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, ...

<p>The Thissavros hydropower and pumped storage project on the Nestos river in northern Greece involved construction of a 172 m high rockfill dam and an underground power house with 300 MW installed capacity. Bedrock at the site consists of gneiss with complex ...

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. ...
