Abstract: The Zhala hydropower station plant was under the threat of rockfalls induced from a high slope, especially in rainy seasons. This paper proposes an innovative protection structure consisting of a pervious concrete wall and ...

Abstract: Sand cushions for passive protection structures could reduce the damage that is induced by rockfall impact. Therefore, evaluation of the peak impact force generated by rockfall on the sand cushion is significant to the ...

Abstract: Grouting has been widely used in the reinforcement of jointed rock masses, and the interface between the rock and cement serves as a crucial binary interface in controlling the strength effect after grouting. In order to ...

Abstract: In rock masses, there might be structural nonstationarity in the joint morphology that influences the shear behavior of rock joints. However, research into this effect is seldom reported. In this study, shear tests on ...
