  • The concrete face rockfill dam is a kind of common water retaining structures. A new structural pattern of rockfill dam, named as anchoring face rockfill dam, is proposed by the prestress cable anchoring the upstream concrete face and downstream concrete framwork. The prestress anchorage cable in the rockfill dam could works together with rockfill and concrete face and framework to keep the stability. The construction method for the anchoring face rockfill dam is expressed. The deformation characteristics and stability of anchoring face rockfill dam are analyzed by the numerical method with Duncan-Chang E-B model. The deformation characteristics and stability of the rockfill dam with and without prestressed anchorage cable are compared and analyzed. According to the deformation characteristics during construction and storage period analyzing results, the anchoring face rockfill dam can increase the dam slope rate. The stability of dam slope is analyzed by using the strength reduction method. It is shown that the width of the bottom of dam for the anchoring face rockfill dam can reduce, and the filling quantity decrease to obtain the economic benefit.
