Investigation of Mechanical Behaviour of Rockfill Materials

, 2023
© 2024 Reza AsadiThe study of the mechanical behaviour of rockfill material, an essential element in diverse geotechnical applications including dams, railway subgrades, and offshore structures, continues to be a critical area of exploration due to its ...

Large-scale shear box tests to determine rockfill parameters

, 2016
A 160 (525 ft) m high asphalt concrete core rockfill dam is developed in an area of very high seismicity in Cetin, Turkey. Topographical constraints of the dam footprint impose a steep outer geometry of the dam, requiring the geotechnical properties of ...

Delayed crushing time for particles of rockfill materials

Yantu gongcheng xuebao
The delayed crushing of rockfill particles is specifically referring to the crushing of particles after loading for a certain period time, which is the basis for the rheological deformation calculation using the discrete element method (DEM).

Safety analysis of rockfill dams during overspill phenomena

, 2020
An increasing interest is rising on the study of rockfill embankment dams during overspilling. Design criteria of earth dams are being reviewed in many countries to guarantee an increasing safety level in front of an exceptional flooding. The possibility

Three-dimensional analysis of water infiltration into the Gouhou rockfill dam using saturated-unsaturated seepage theory

, 2006
The Gouhou Dam was a concrete-faced rockfill dam built in a steep canyon that collapsed in 1993 due to internal erosion during the initial reservoir filling. In this paper, the process of water infiltration into the originally unsaturated rockfill dam is

Research Progress on Failure Probability Analysis of Earth-Rockfill Dams Based on Random Field Models

Renmin Zhujiang
The physical and mechanical parameters of rock and soil inside earth-rockfill dams have strong spatial variability. Random field models can accurately model and analyze failure probability through scientific methods, which helps to better evaluate dam ...
