The deformation of arch dam during impoundment is critical to evaluate the safety dam, which influenced by many factors that have different action mechanisms. After monitoring data at stages were comprehensively analyzed, a finite element simulation analysis model can consider real temperature, stress and was set up with help method based on whole process effectively separate single caused wate...

the number of constructed dams has been largely increased due to high demands of water supplies, and earth dams are the most common types since they are more compatible to the environment. nevertheless, the stability of these important structures during earthquakes has to be carefully evaluated and guaranteed. in the past, earth dams usually designed with pure clay core, but in recent decades t...

the behavior of earth dams has particular complexities against dynamic forces and its assessment requiresdetailed and scientific analysis. the farrokhi earth dam is a heterogeneous type with vertical clay core, built 150 km away from birjand and 41 km away from qaen on the farrokhi river. there are concernsregarding the stability of this dam in the event of a future severe earthquake especially...

In this paper, the dam of Baihetan Hydropower Station was taken as an example to establish a refined three-dimensional finite element model (FEM) dam-dam foundation based on comprehensive analysis safety monitoring data during whole life cycle and simulation for process dam, so accurately understand working behavior impounding process, do feedback influence mechanism overall deformation arch in...

Global Navigation Satellite Systems (GNSS) receivers are nowadays commonly used in monitoring applications, e.g., in estimating crustal and infrastructure displacements. This is basically due to the recent improvements in GNSS instruments and methodologies that allow high-precision positioning, 24 h availability and semiautomatic data processing. In this paper, GNSS-estimated displacements on a...

In order to monitor dam safety condition better, a Dynamic Bayesian Networks (DBN) model is developed to overcome the shortcomings of the ordinary monitoring methods in this paper. Ordinary methods include comprehensive assessment methods and numerical simulation methods. Comprehensive assessment methods have shortcomings such as weight determination, scale difference, variables correlation, et...
