The RCC Arch Dam Analysis during Overload

It does numerical analysis on the overload of RCC arch dam named wanjiakouzi, through the analysis, we try to find the damage process of the dam. It does elastic-plastic analysis by FEM. Result shows that the horizontal cracks are usually a very important symbol, it means the dam will reach its ultimate capacity.

Deformation Characteristics of Roller Compacted Concrete under Triaxial Stress State

Experiments of two graded-aggregates concrete used for RCC arch dam are conducted. The experiment includes three states: direct shear state, compressive-compressive-shear state and tensile-compressive-shear state. Comparison and analysis of the deformation characteristics of body specimens and layer specimens are carried out. Influences of different stress states on body specimens and layer specimens are also studied in this paper.

Safety Analysis of Arch Dam with Strength Reverse Method

Arch dam’s failure is a super nonlinear irreversible process. The research on process of it would give quite important information for safety evaluation. In this paper, it analyses overload of the highest RCC arch dam of the world by strength reverse method and shows the process of dam’s failure from normal operation, local deformation to overall failure

Distributed Optical Fiber in High RCC Arch Dam Project

As the highest RCC(Roller Compacted Concrete) arch dam under construction around the world, Wanjiakouzi adopted advanced distributed temperature system (DTS). This paper summarizes the network design, technical requirements as well as the protection precautions of fiber connector and monitoring port of temperature measurement system of optical fiber in high RCC arch dam in Wanjiakouzi. It can be indicated that the accuracy and reliability of DTS by comparing fiber optic temperature values with the conventional thermometer measured values. The analysis and monitoring results show that the temperature measurement system of optical fiber can truly monitor and reflect the change process of heat of hydration of RCC, gradation and the cooling water pipe to temperature.

Failure Process Analysis of Arch Dam with Explicit FEM

Arch dam’s failure is a super nonlinear irreversible process. The research on process of it would give quite important information for safety evaluation. In this paper, it analyses overload of the highest RCC arch dam of the world with explicit FEM and shows the process of dam’s failure from normal operation, local deformation to overall failure by water-level overcharge method. It gives a more direct and precise safety factor. This method is also can be used in other structures.

Safety Analysis of Arch Dam

Arch dam’s failure is a super nonlinear irreversible process. The failure process of it is quite important for safety evaluation. It analyses overload of the highest RCC arch dam of the world with explicit FEM and shows the process of dam’s failure from normal operation, local deformation to overall failure by water specific gravity overcharge method. It gives a more direct and precisely safety factor. This method is also can be used in other structures.

Failure Process Analysis on Overload of Arch Dam

Arch dam’s failure is a super nonlinear irreversible process. We can find the damage mechanism from research of it and get a more reasonable and perceive safety factor. It analyses overload of the highest RCC arch dam of the world and shows dam’s failure process by water specific gravity overcharge method and water-level overcharge method. It gets overload safety factor from study on arch dam’s failure process and also gives the reason that why different methods get different safey factor.
