Witryna2 kwi 2024 · Two model tests are presented to investigate the performance of berm and elastic dam for debris flow [2,3]. Three papers adopted the advanced meshless method to simulate model tests and real debris flow [4,5,6]. ... The essential part of barrier design is the determination of impact force. However, an impact force is mostly … WitrynaCiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): On the aspect of impact force, present design of filter dams and check dams often refers to the empirical models. However, after reviewing literature, we found that there is a great variety between models. It will be an uneconomical way if we overestimate the …
Deriving Debris‐Flow Dynamics From Real‐Time Impact‐Force …
Witryna1 paź 2024 · The dynamic impact force of debris flow on dams with a curved upstream face curved was investigated using laboratory experiments and a theoretical approach. Equations describing the impact force and maximum run-up height were derived. The experiments and theoretical considerations reveal that the impact force and … Witryna1 gru 2024 · The check dam was regarded as an elastic part, and it was modeled as being 1.5 m high, 1 m wide, and 0.5 m thick. The Eulerian elements were applied to the debris flow, erodible sediment and void area (Fig. 1 a), and the Lagrangian elements were applied to the bedrock components and check dam (Fig. 1 b).Gravitational … port pilot newspaper southport nc

Witryna1 cze 2008 · When the dam is impacted by debris flow, the force on the dam is produced by the momentum variation of the debris flow. The debris flow was … Witryna17 maj 2024 · Debris flow impact force is an important factor for controlling structural damage, and it is the key factor for engineering design and risk assessment. Variation laws of debris flow impact force play an important role in preventing check dam impact damage and providing technology, data and support for check dam construction. … Witryna11 wrz 2015 · [9] Huang HP, Yang KC and Lai SW 2007 Impact force of debris flow on filter dam Geophysical Research Abstracts 9 03218.
