Piping akibat erosi internal dapat menyebabkan kegagalan struktur pada bendungan urugan. Pembentukan piping yang dimulai bagian hilir kaki dipengaruhi oleh gradien kritis material (Ic) dan hidrolik keluaran (Ie). Nilai perbandingan kedua parameter tersebut apabila melampaui batas tertentu memicu terbentuknya piping. Selain itu, untuk mengurangi risiko maka debit rembesan diizinkan adalah tidak ...

Abstract Internal erosion is susceptible to occur in conditions where there are cracks or pre-formed cavities at the interface between dam foundation and embankment. The initiation of internal related critical gradient ( I c ) hydraulic xy a certain position. addition repair materials improvement will change total head, especially on foundation, so value also simultaneously from upstream downst...

Dams and ponds as engineering structures pose various risks during design, construction operation. Deformation in dams, slope stability problems or excessive pore pressure can cause serious damage that cannot be prevented. It is critical to position these areas correctly evaluate the potential quantitatively. In rockfill work needs done planning project phase, especially on infiltration safety....

Purpose. The purpose of study is a predictive assessment stress-strain state the "DTEK Ladyzhynska TPP" ash dump and changes in hydrodynamic hydrogeochemical modes within its location area conditions designed reconstruction. methodology. Comprehensive around site defining hydrogeomechanical stability enclosing dams performed based on results numerical modeling groundwater flow transport, using ...

The study of the rainfall infiltration mechanism unsaturated soil has always been a hot issue in field geotechnical engineering. It is worth studying which parameters should be introduced to characterize characteristics calculation and analysis infiltration. In this paper, Fredlund–Xing model was quoted SEEP/W module Geostudio software, transient numerical under same duration T different intens...

Abstract Today, statistics show that most of the accidents leading to dam failures occur in case embankment dams and, therefore, authors have chosen analyse state safety operation Buftea Dam Romania. The need for such analysis is sustained by fact has an important role flood protection on Colentina River, which flows through a number localities vicinity capital city Romania, Bucharest (Buftea a...

In this paper, a mesh-free approach called smooth particle hydrodynamics (SPH) is proposed to analyze the seepage problem in porous media. In this method, computational domain is discredited by some nodes, and there is no need for background mesh; therefore, it is a truly meshless method. The method was applied to analyze seepage flow through a concrete dam foundation. Using the SPH method, the...

Landslides bring destruction to buildings, and nearby located structures mostly occur in rural areas. Such hazard commonly takes place mountainous areas Central Asia. Kazakhstan region has highly vulnerable rainfall-induced landslides South-Eastern parts due presence of many mountains. The purpose the research is demonstrate effect slope geometry on stabilityunder heavy rainfall Almaty, Kazakhs...

Many coal mines are being abandoned for economic and environmental reasons in China. The repurposing of open-pit into pumped storage hydropower (PSH) can help with the renewable energy, improve mine environments, provide added value. Construction PSH plant will change water level pit, which is envisaged as lower reservoir, thus influencing slope stability. In this study, Fushun West Open-Pit wa...
