  • Published : 2004.09.01

Abstract

A method of double-pole construction is developing to strengthen the mechanical intensity of the electric poles. Therefore the mechanical properties of the double-pole were researched in this paper. First, considering field special quality electric poles were established. In the next tensile force was applied and stress distribution and fatigue load were examined. When a base of the pole is concrete, mechanical intensity of the double-pole increased about 1.7 times compared a single pole. In the case of general soil base, the concrete base should be needed to expect the reinforcement effect of the double-pole.

본 논문은 강도부족 전주의 경제적 보강방안으로 추진 중인 겹전주 공법개발과 관련하여 기계적 강도평가를 위해 배전용 콘크리트전주의 수평 재하시험을 수행한 것으로, 현장특성을 최대한 고려하여 전주를 건주한 상태에서 전주의 응력분포 및 피로하중을 검토하였다. 실험결과, 지반이 콘크리트인 경우 단전주보다 강도증가 효과는 최대 1.7배로 증가되었으며 일반토사지반의 경우 겹전주의 보강효과를 확보하기 위해서는 지반의 콘크리트 보강이 필요한 것으로 분석되었다.
