점성토 지반에서 석션기초의 단계별 Standard 해석과 CEL 해석의 관입성능 비교

Abstract

Double suction plate anchor is consisted two small suction anchors and plate. Multi-anchor has an advantage that they can withstand the horizontal load and moment and designed the structure stiffer. The simulations have been conducted for the bearing capacity of double suction plate anchor in clay with CEL(Coupled Eulerian-Lagrangian) Method and Standard model. The bearing capacity between CEL Method and Standard model were compared and evaluated. CEL Method cannot depict the effect of suction pressure. To improve this limitation, this research adopted the concept of the mobilized factor as 0.15 to 0.45 from Cho et al. (2000) and the adhesion factor as 0.2 to 0.5 from API (2005). The decreased cohesion of claymeans the soil strength reduction due to the water flow caused by the applied suction pressure during installation. In this research, the simulations have been conducted for estimating the behavior of double suction plate anchor using CEL Method with decreased cohesion. Based on the results, the capabilities of the new CEL approach are evaluated and validated.he bearing capacity of double suction plate anchor in clay with CEL(Coupled Eulerian-Lagrangian) Method and Standard model.
