| Analysis of rock burst event in deep tbm excavation of pahang-selangor raw water transfer tunnel /Romziah Azit, Mohd Ashraf Mohamad Ismail Tunneling under high overburden and high in-situ stress can pose a major threat to the tunnel construction due to the phenomenon of rock burst. Rock burst is a typical phenomenon caused by underground excavation due to stress release and rock explosion where the rock masses broken in large or small pieces. Thus, predicting the occurrence of this ph... | 17/12/2018 | Romziah Azit - Author Mohd Ashraf Mohamad Ismail - Author | ||
