Mechanical Properties and Damming Behaviors of Gravelly Solidified Soil for Earth-Rock Dam Core Wall
KSCE Journal of Civil Engineering, 2021 To decrease the arch effect of core wall effectively has become an important requirement for high earth-rock dams. To address this issue, a soil solidifier was used to improve the properties of gravelly soil. This study investigated the durability and mechanical performances of gravelly soils mixed with different proportions of solidifier through the ...

Study on geomembrane seepage property of earth-rock dams
IOP Conference Series: Earth and Environmental Science, 2019 AbstractAs an anti-seepage material, geomembrane is widely used in earth-rock dams engineering. However, the seepage calculation of geomembrane earth-rock dams has not been studied theoretically. According to the permeation mechanism of geomembrane, it can be divided into two categories: one is the permeability of itself; the other is the defect ...
