| Abstract |
As construction work on soft ground increases, many researchers have studied to secure the stability of trafficability with interest in construction safety accidents due to reinforcement work. Although the stability of soft ground is evaluated based on the allowable bearing capacity of theoretical equations proposed in the literature such as Yamanouchi and Meyerhof formulas, further numerical verification also requires comparison of the stress increase (Δσz) and deformation of the distributed contact pressure on the soft ground. In this study, the deformation of the soft ground is compared with the increasing the seam tensile strength of geotextile using the finite element analysis program, and the stress increase is investigated by variation of the distributed contact pressure by appling input data of case study. |
