专家简介
Professor Yoon-Ho Cho earned his Ph.D. in Transportation Engineering from the University of Texas at Austin, USA, and possesses a comprehensive international academic background. He previously conducted research at the Center for Transportation Research (CTR) at the University of Texas and served as a senior researcher at the Korea Institute of Civil Engineering and Building Technology (KICT). Since 1998, he has been a faculty member in the Department of Civil and Environmental Engineering at Chung-Ang University, Korea, where he is currently a Professor. He has also served as Dean of the College of Engineering and Director of the Engineering Education Innovation Center. In terms of academic leadership, Professor Cho is a co-founder of the BESETO (Beijing-Seoul-Tokyo) International Conference on Concrete, promoting high-level academic exchanges in concrete and pavement engineering in East Asia. He has served as Vice President of the Korean Society of Road Engineers, President of the Korean Brick Association, and Organizing Committee Chair of the International Conference on Concrete Block Paving (ICCBP). At the government and industry level, Professor Cho has long served as a member of the Infrastructure Management Committee under the Prime Minister's Office of Korea. He has also participated as a core expert in overseas infrastructure projects in countries including Honduras, Sri Lanka, Indonesia, the Philippines, Cambodia, and Laos, providing technical consulting and capacity building.

This lecture presents an integrated study combining Finite Element Analysis (FEA) and Accelerated Pavement Testing (APT) to evaluate the structural performance of Continuously Reinforced Concrete Pavement (CRCP) and Jointed Reinforced Concrete Pavement (JRCP) constructed on discontinuous precast segmented foundations in tunnel environments. Given the unique structural constraints of tunnels, including limited space, restricted base layer treatment, and segmented substructure, conventional pavement design methods may not adequately capture the mechanical behavior of such systems. The study develops detailed three-dimensional FEA models to simulate stress distribution, crack propagation, and load transfer efficiency at segment joints under both traffic loading and temperature gradients. APT is then conducted to validate the numerical predictions through controlled, full-scale pavement testing. Key performance indicators including slab deflection, joint load transfer efficiency, crack spacing, and reinforcement strain responses are compared between the two pavement types. The findings provide a deeper understanding of how discontinuous foundation conditions affect pavement response, and offer practical design recommendations for selecting and optimizing rigid pavement systems in tunnel applications.
