Study of Gravelly Soil Core Material Using a Large-Scale Triaxial Wetting Test
Applied Sciences, 2023 Wetting deformation has a significant impact on dam safety, and is one of the leading causes of the long-term deformation of dams. For dams to operate safely, it is crucial to precisely estimate the extent of wetting deformation using a reasonable calculation model.

Experimental study on strength and deformation characteristics of gravelly soil core materials
岩土工程学报, 2020 For the earth core rockfill dam, the coordination of the strength and deformation of the dam is a key issue that restricts the dam construction. The deformation of the gravelly soil core materials is large, which leads to the transfer of the load to the ...

Influence of coarse-grained content in the gravelly soil on steady seepage of high earth-rock dam
Shuili Shuiyun Gongcheng Xuebao, 2021 Gravelly soil has been mostly used as the core material of the high earth-rock dam. When the coarse-grained content of a gravelly soil (referring to the mass fraction, the same below) may exceed 50%, the coefficient of permeability of a gravelly soil is ...
