| Rock overstressing in deep tunnel excavation of pahang-selangor/Romziah Azit, Mohd Ashraf Mohamad lsmail, Sharifah Farah Fariza Syed Zainal Tunneling under high overburden and in-situ stress may cause tunnel instability because of rock overstressing. Evaluating overstressing in deep hard rocks is crucial to minimize excavation risks. The excavation of the Pahang-Selangor Raw Water Transfer Tunnel is evaluated in this study. A potential overstressing problem is expected at a tunnel dept... | 3/9/2020 | 6/9/2009 | Romziah Azit Mohd Ashraf Mohamad lsmail Sharifah Farah Fariza Syed Zainal | |
| Numerical analysis of TBM tunnel lining behavior using shotcrete constitutive model /Prof Madya Dr. Mohd Ashraf Mohd Ismail Shotcrete is a ftlndamental support element for tunnels and underground constructions. Shortly after application, shotcrete linings undergo a high load while the ordinary concrete is not fully hardened yet. Therefore, the time-dependent behaviour of the shotcrete material must consider. Traditional approaches assume a linear elastic behaviour using... | 3/9/2020 | 5/5/2018 | Prof Madya Dr. Mohd Ashraf Mohd Ismail | |
