The Benínar Dam, located in Southeastern Spain, is an earth-fill dam that has experienced filtration issues since its construction 1985. Despite the installation of various monitoring systems, data collected are sparse and inadequate for dam’s lifetime. present research integrates Multi-Temporal Interferometric Synthetic Aperture Radar (MT-InSAR) modeling to validate this dam, opening way enhan...

Horizontal displacement of Hoa Binh dam in operation phase is analyzed and then forecasted by using three methods: the multi-regression model (MTR), Seasonal Integrated Auto-regressive Moving Average (SARIMA) Back-propagation Neural Network (BPNN) model. The monitoring data Dam 137 periods, including horizontal displacement, time, reservoir water level air temperature, are used for experiments....

Abstract Displacement monitoring method of reservoir dam is a key research topic at present. In order to better display the overall efficiency horizontal displacement and vertical monitoring, numerical simulation analysis ecological small based on maximum entropy algorithm proposed. The virtual value calculated by algorithm, probability distribution function random variables obtained. comprehen...

Dam is set in large hydropower station. Cushion pool built behind the dam for flood discharge and energy dissipation of reservoir. Operation some time, dewatering structure safety which study, then cushion filled. Temporary dewater filled system used by previous engineer, but arranged controlled hard. Based on need filling, an example Baihetan station, necessity feasibility are study. Then a pe...

The article is devoted to the dynamic problems of studying strain state earth dams under impacts. A method developed for solving wave determine stress-strain structures, in particular, dams. Based on use finite difference method, an algorithm and calculation formulas were that have second-order accuracy time coordinates. advantage implementation complex nonlinear deformation models, taking into...

Abstract Seismic analysis of a fractured dam is generally complex problem. This paper presents an earthquake behavior investigation concrete gravity considering dam-reservoir--foundation rock interaction. The Koyna profile, located in India, adopted this study. nonlinear finite element analyses are conducted taking into account empty and full reservoir cases, to exhibit the hydrodynamic e ect w...

Global Positioning System (GPS) has been confirmed to be a feasible tool measure displacement of civil engineering structures. In this paper, we report on an analysis annual deformations pumped-storage power station dam using historical GPS observations. Data spanning more than nine years are resolved the GAMIT (GPS at MIT) software, and time-series method is employed extract linear trends cycl...
