탄성 지반내 깊이 묻힌 앵커판에서 경계파괴의 영향

Abstract

지반과 구조물의 상호작용 문제는 그 범위가 광범위하고 또 새로운 문제들이 떠오르?? 있다.

본 논문에서는 탄성체 지반에 깊숙이 묻힌 강성 디스크 앵커판에서 디스크 앵커 주위 경계파괴가 지반의 축방향 강도에 미치는 영향에 관하여 연구하였다.

등방탄성체 속에 묻힌 앵커는 축대칭이므로 3차원 문제를 2차원으로 귀착시켜 유한요소법을 사용하였으며 유한요소법의 적합한 적용성을 검토하기 위하여 적분방정식에 의한 해석과 그 결과를 비교하였다.

본 연구의 결과를 이용하여 탄성계수의 변화, 포아송비의 변화 등 지반의 강도를 결정 짓는 변수들에 대한 값의 변호가 축방향 강도에 비치는 결과에 관하여 연구하였다.

The analysis of interaction between structural elements such as beams, plates, etc. and elastic media is interests of several branches of engineering. Such solutions are particularly importance in analytical studies related to structural foundations reaction on soil and rock media.

The class of problems which deal with the loading of plate shaped objects embedded in elastic media provides a useful basis for the modelling of the short-term or working load range stiffness of anchor plates.

In this paper we focus on the problem of a rigid circular anchor plate embedded in bonded contact with an isotropic elastic soil mass of infinite extent. The elastic medium beyond the boundary of the rigid disk anchor contains an in-plane cracked region of finite extent.

This study is concerned specifically with the evaluation of the elastostatic stiffness of the embedded anchor in the presence of a cracked region emanating from the anchor region.

Provision is made on the analysis for the consideration of breakaway of the anchor from the underlying soil.
