معرفی
Rentai LIU is a Professor and doctoral supervisor at Shandong University's School of Civil Engineering, affiliated with the Geotechnical and Structural Engineering Center. He earned his Ph.D. in Geotechnical Engineering from Shandong University in 2012 and subsequently joined the faculty, with a postdoctoral stint at Shandong Energy Group (2012-2015). His research focuses on controlling geological hazards in underground engineering and developing innovative grouting technologies.
Research Interests: Dr. LIU specializes in dynamic water grouting theory, quantitative grouting design for water-rich strata, and novel material development. His work addresses practical challenges like water inrush disasters, sand layer stabilization, and rock mass reinforcement. Key innovations include cement-based anti-dispersion grouts and expansion materials for high-pressure water surges, applied in major infrastructure projects across China.
Research Trends: His publications (2011-2019) predominantly explore grouting material properties, underground water control, and geomechanical modeling. Recent work emphasizes computational simulations, subsea tunnel risks, and sustainable materials like pervious concrete.
