Abstract

현재로서는 인발저항 메카니즘에 많은 불확실성들 즉, 구속된 조건에서의 다일레이션, 인발저항영역, Transition zone의 존재, Debonding 메카니즘, Boundary condition등 이 내포되어있어, 아직까지 확립된 이론이 존재하지 않는다. 인발저항력 추정을 위해 그 동안 수많은 시도와 노력이 있었음에도 불구하고, 현장 인발시험이 현재 지반설계에 가장 적합한 방법으로 지금까지 통용되고 있는 실정이다. 쏘일네일설계시 요구되는 몇가지 중요한 문제들을 제기하고 그에 대한 나름대로의 해석과 결론을 제시하였다.
