This paper has done continuous on-site experimental researches on temperature field and temperature effects that are under the influence of hydration heat of concrete during the molding process of dumb-bell CFST arch bridge. Analysis on time-history law of temperature field and temperature effects is made. Results reveal that temperature variation of hydration heat of the concrete within the st...

The aim of this paper is to describe how ground-based radar interferometry can provide displacement measurements of earth dam surfaces and of vibration frequencies of its main concrete infrastructures. In many cases, dams were built many decades ago and, at that time, were not equipped with in situ sensors embedded in the structure when they were built. Earth dams have scattering properties sim...

In this paper, case study on outlet cracking is first conducted for the Goupitan and Xiaowan arch dams. A nonlinear FEM method is then implemented to study effects of the outlets on integral stability of the Xiluodu arch dam under two loading conditions, i.e., normal loading and overloading conditions. On the basis of the case study and the numerical modelling, the outlet cracking mechanism, ri...

In this article, an analytical model is presented for the simulation of the thermal behavior of dams that are subjected to the environmental thermal action during service. The method of solution adopted as well as the evaluation of the different parameters is described in detail. Also, the theoretical results that are predicted by the model are compared with experimental results obtained throug...

The shape of an arch dam has of paramount importance in its ultimate behavior and eventually settles all design criteria. Variable curvature arch dams evolved to be economical in shape optimization studies. In Finite Element Analysis, the arch dam geometry is to be modeled very accurately. But the arch dam geometry may be varying in the three dimensions and with irregular boundaries depending o...

The social, economic, and environmental consequences of the failure an arch dam make it essential to evaluate its dynamic response mitigate risk a disaster. Since slenderness flexibility these dams tend increase fluid-structure interaction during earthquake, this work compares hypothetical in Marañón river, northern Perú, for both full empty-reservoir conditions. Three formulations were used es...
