Stress-strain state of some special places in earth dam from viewpoint of hydraulic fracturing

Publikováno v: Stroitel’stvo: Nauka i Obrazovanie, Vol 14, Iss 1, Pp 45-60 (2024)

Introduction. In the current process of climate change, the phenomenon of unusual rainfall and flooding is causing widespread flooding and causing great loss of life and property. In addition, the most vulnerable structures are dams and reservoirs. A

Autor: G. V. Orekhov, Tran Manh Cuong

Publikováno v: Vestnik MGSU, Vol 19, Iss 2, Pp 281-293 (2024)

Introduction. In the current climate change conditions, the protection of irrigation structures, especially dams, is a very important task. Seepage is one of the main causes of dam failure, so it is very important to investigate the seepage regimes a

Seepage strength of the dam soil in the area of a round-shaped culvert spillway

Autor: G. V. Orekhov, Tran Manh Cuong

Publikováno v: Vestnik MGSU, Vol 18, Iss 8, Pp 1272-1282 (2023)

Introduction. There are many destructions of earth dams in the world due to the loss of seepage strength of soils of the dam body or foundation. The seepage stability of soils is directly related to the phenomenon of hydraulic fracturing (HF), so pre
