Abstract:

More and more high dams with huge reservoirs have been built in China in recent years. A lot of research work on the causes of cracking in galleries of low concrete dams has been carried out at present, while studies on that of high concrete dams are less with the lack of systematic cognition. Based on that, the research on high concrete dams is conducted in this paper, using the method of finite element simulation. It is proven that self-weight action has more influence on the stress of arch crests of galleries existing in high concrete dams, especially the galleries whose overlying concrete

Monitoring data of the arch crown dam section of the Geheyan concrete gravity arch dam were qualitatively and quantitatively analyzed. The analysis results show that the measured data and year changes of the dam horizontal displacement are small, the influence of the water level and temperature on the arch crown dam section is normal, the influence of the aging on the dam horizontal displacement is little, and the aging component has become stable. Therefore, it can be shown that the arch crown dam section of the Geheyan concrete gravity dam is in elastic state, and the horizontal displacement

Abstract:

The construction of double-curvature arch dams is an attractive solution from an economic viewpoint due to the reduced volume of concrete necessary for their construction as compared to conventional gravity dams. Due to their complex geometry, many criteria have arisen for their design. However, the most widespread methods are based on recommendations of traditional technical documents without taking into account the possibilities of computer-aided design. In this paper, an innovative software tool to design FEM models of double-curvature arch dams is presented. Several capabilities are allowe

A better understanding of the dynamic behaviour of dams requires strong-motion instrumentations. In particular, it is necessary to observe the free-field motions at the dam sites and the effective motions along the abutments, and to determine the dynamic properties of dams and their response to severe earthquakes. Instrumentation schemes are developed for arch dams, gravity dams and embankment dams, considering specific observational needs and objectives. The technical specifications to be satisfied by the accelerographs and the arrays are developed. Four arrays, which have been installed in S

Dams considered as one if very important infrastructure, they are lifeline structures and have a vital role our economics and social life. A concrete gravity dam is one of wide used dam worldwide, it constructed from reinforced concrete and his typical cross section is triangular, the other type is arch section. A gravity dam can be combined with an arch dam into an arch-gravity dam for areas with massive amounts of water flow but less material available for a purely gravity dam. The inward compression of the dam by the water reduces the lateral (horizontal) force acting on the dam. Thus, the

Abstract:

A new concept for establishing the damage model for high concrete dams under earthquakes based on damage mechanics is presented in this paper. Unlike the conventional approach of considering the residual deformation by means of plastic-damage coupling, the proposed approach relates the degraded apparent elastic moduli of loading and unloading directly to the material experimental data. As such, the nonlinear analysis of the seismic response of dam-foundation systems is simplified and more reasonable, with no recourse to plastic-damage coupling.

The coefficient of anti-sliding stability of each dam segment and the safety degree of dam body were also calculated.

And the crack-induced displacement is generally incorporated into the time-dependent component, thus weakening the interpretability of the model.

External deformation monitoring of high core rock-fill dams (HCRFDs) is an important and difficult part of safety monitoring.

However, the small angle method has low accuracy and a low automation degree, and there is multicollinearity between the independent variables, which affects the parameter estimation and leads to the failure of model establishment.
