研究室紹介
Professor HangSeok Choi's research lab specializes in geotechnical engineering with a focus on slope stability, grouting mechanics, and tunneling risk analysis. The lab investigates advanced soil behavior modeling, including stress-dependent shear strength parameters and grout flow dynamics in porous media, to improve the reliability of geotechnical design. It also develops innovative risk assessment frameworks—particularly causal network-based models—for sustainable tunneling projects using shield tunnel boring machines (TBMs). The lab integrates experimental insights with theoretical modeling to address practical challenges in underground construction and ground improvement.

Selected Papers
15This paper presents recommendations for selecting the type and magnitude of drained shear strength parameters for analysis of landslides. In particular, the importance, existence, and use of the cohesion shear strength parameter is reviewed. For slope stability analyses, it is recommended that the shear strength be modeled using a stress dependent failure envelope or a friction angle that corresponds to the average effective normal stress acting on the slip surface passing through that particula
Abstract The groutability depends on the properties of the grout, its injection processes, and on the mechanical properties of the soil formation. During the process of pouring cement‐based grouting into a porous medium, a variation with time occurs in the viscosity of grout suspension. In addition, the particle filtration phenomenon will limit the expansion of the grouted zone because cement particles are progressively stagnant within the soil matrix. In this paper, a closed‐form solution was d
