Abstract: During shield tunneling, the soil arching effect in front of the excavation face can effectively reduce the impact of excavation on the surrounding environment. This effect was studied with different depth/diameter ratios ...

Abstract: Sand solidification technology is widely applied in engineering. This paper presents experimental methods to analyze the effect of adding urea to a culture medium for sand solidification. The results show that adding urea ...

Abstract: AbstractThe phononic-like crystal (PLC) metaconcrete material with vibration reduction performance, proposed by the authors based on local resonance metamaterials, provides a new technology for solving low-frequency vibration ...
