This study attempts to use a dam breach model reproduce the well-monitored outflow hydrograph obtained during breaching process of Tangjiashan barrier lake, which was formed by landslide triggered Wenchuan earthquake on May 12, 2008 in China. The key parameters that affect results, such as soil erosion and lateral enlargement, are reviewed using field measurements followed extensive sensitivity studies. present paper advocates hyperbolic for rate circular slip surface approach contribute...
Abstract Check dams are widely constructed on China's Loess Plateau, which had a total number of 58,776 by the end 2019. Great achievements in check dam construction have been gained regarding economic and environmental impacts. This study reviews remarkable benefits land reclamation improvement sediment reduction entering Yellow River. However, flood incidents frequently reported for past decades, has attracted more attention context climate change extreme rainfall events recently. Advances...
This study has reviewed the emergency action and drainage process of Xiaogangjian, Xiaogangjian-lower, Yibadao cascade landslide dams that were formed during 2008 Wenchuan earthquake in China's southwest Sichuan Province. In order to minimize hazards caused by dam breach flood, mitigation works carried out. Using underwater explosion mechanical excavation, heights Xiaogangjian lowered 8 5 m, respectively. On June 12, Dam was overtopped, followed failures two downstream dams, resulting a...
Gradation has an important influence on the mechanical properties of earth and stone materials after compaction, a reasonable gradation is key to ensure compaction quality. In this paper, set detection system based digital image processing was proposed, which suitable for in construction sites. The obtained images were taken from multiple directions transport vehicle, used thresholding method segment images, detected particle contours through edge algorithm Canny realize recognition size,...
For sluices built on soil foundations, seepage safety of the foundation is one most concerns during operation sluices. Monitoring data could reflect real behavior in foundation, but which shortcoming that generally only local states can be measured. The field whole analyzed by numerical simulation. permeability coefficients materials significantly affect simulation results; however, it difficult to accurately determine values coefficients. In this paper, an approach based response surface...
Abstract To quantitatively measure the erodibility of soil, including incipient shear stress and scouring rate, a new measurement method was proposed. The system contains cylindrical erosion test apparatus (CETA) calculation shearing stress. CETA developed to relation between rate water velocity, which mainly composed power system, circulation data acquisition system. Using proposed method, by flow clarified. On basis single-size soil samples from Tangjiashan Yigong landslide dams were...
Abstract Landslide in reservoirs imposes challenges to reservoir operation and dam safety management practices. The understanding of the landside mechanism during is crucial landslide‐related risk migration. During from 2018 2021, a massive landslide occurred with over 10 7 m 3 total volume on bank NE reservoir. surface movement characteristics before after occurrence landslides region scale were detected interpreted by Sentinel‐2 time series images. Experimental studies conducted...
In the design process of earth-rock dam, slope stability problem was always focused on. The shear strength rockfill in dam had strong nonlinear characteristics. characteristic directly affected factor safety (FOS) and determination critical slip surface. parameter related to minimum principal stress σ 3 closely. And value close relationship with deformation characteristics filling material etc. Strength reduction method has been widely used solving FOS stability, this advantage on searching...
Effective temperature control measures are crucial for achieving regulation and preventing cracking in the dam body during construction of large-volume concrete gravity dams. Due to low ambient temperatures winter, it is especially important focus on cold regions. This paper employs a numerical simulation method that takes into account simulate predict overall stress fields Guanmenzuizi Reservoir Dam, validates these simulations with field monitoring results. study finds significantly...
