Dynamic Finite Element Analysis of RCC Gravity Dam

Advanced Materials Research, 2011
Dynamic finite element analysis for a RCC gravity dam is implemented by using response spectrum method in this paper. Firstly, three-dimensional finite element model is established, and then the subspace iterative method is used in the modal analysis of the gravity dam.

Extensometers results correction in concrete dams: A case study in RCC Zhaveh Dam

Structural Monitoring and Maintenance, 2017
Since extensometers are used to determine the absolute deformation of foundation and abutments and all results are obtained in reference to the base rod, the accuracy of these results has been constantly a subject of debate. In this regard, locating and installing extensometers outside the range of effect zone is also another challenge.

Cracking Mechanism of RCC Dam Surface and Prevention Method

Advanced Materials Research, 2011
Using low placement temperature and proper water pipe cooling water, the cracks are rarely appears in the interior of the dam, but the surface of the dam is prone to cracking. During the construction, the surface of the dam may be wet due to several factors such as creep, maintenance and so on, so the effect of the heat preservation is always been over-

Hydraulic design of stepped spillways over RCC dams

2020
Based on experimental data gathered on a stepped chute, renewed criteria are proposed for the hydraulic design of stepped spillways over RCC dams. In particular, new empirical models are presented for the prediction of air entrainment and energy dissipation down the stepped chute.

Deep Anti-Sliding Stability of Wudu RCC Gravity Dam

Advanced Materials Research, 2012
The deep anti-sliding stability of dam foundation has been an important issue in the study of dam field. Rigid body limit equilibrium method and nonlinear finite element method have been adopted on the analysis of sliding stability. In the current paper, the joint element is used to simulate faults, interlayer shear zone and slight inclined fissure ...

THE DESIGN AND CONSTRUCTION OF LARGE RCC DAMS

2005
The paper traces the development of RCC (roller-compacted concrete) dams 1970s, including the extensive work done in the UK in 1978/79, to the present time RCC dams well over 200 m in height are being designed and constructed. Brief made of the two very small RCC dams in the U. rrK.
