Numerical Analysis of Factors Influencing the Ground Surface Settlement above a Cavity. [PDF]
Materials (Basel), 2022 In this study, ground stability was evaluated through vertical displacement distribution and surface settlement results. In particular, a finite element analysis was conducted considering various factors (namely, cavity type and area, traffic load, pavement thickness, and elastic modulus) that affect a road above a cavity.
