Abstract

This paper studies the discharge capacity of vertical drain boards that is controlling hydraulic gradient among many factors in the specification. The KS K 0940(2008), a testing method based on the conventional Delft type method for measuring the discharge capacity of a vertical drain, was specified in Korea Standard recently. In this test method, the variation in hydraulic gradient can result in large differences in the discharge capacity for the same vertical drain board.

본 연구에서는 국내에서 사용하고 있는 연직배수재의 통수능시험 평가방법과 국내 관련 시방기준들을 고찰하고 연직배수재통수능 시험시 결과에 영향을 미치는 인자로 동수경사 변화에 따른연직배수재의 통수능 시험 결과를 분석하였다. 국내 연직배수재의 통수능 평가시험방법으로 기존 Delft 방법에 근거한 KS K 0940(2008)이 최근 한국표준으로 등재되었으며, 이 시험방법을 사용하는 경우 동수경사의 변화에 따라 연직배수재의 통수능의 차이가 크게 나타날 가능성이 있는 것으로 확인되었다.
