초록

본 연구에서는 주방식 지하구조물에서 지보재 설계를 위한 매개변수 연구를 수행하였다. 지보재 설계에 앞서 설계에 필요한암주와 공간의 형상별 천단변위, 최대 주응력, 소성영역에 대한 해석을 수행하였다. 해석에 사용할 매개변수를 최적화 하기위해주방식 지하구조물의 대상 심도와 지반 조건은 기존 지하철 정거장 건설 사례를 분석하여 결정하였으며 지하공간의 활용 목적에따라 암주의 형상과 공간의 형상을 설정하여 총 180가지의 경우를 선택하였다. 매개변수 해석을 통해 획득한 결과는 향후 지하구조의안정성과 공간 활용성, 시공장비의 적용성을 고려하여 지보재 설계와 설치 여부를 판단할 수 있는 근거자료로 활용될 수 있을 것으로판단된다.

Abstract

In this study, in order to suggest the design method for supports in the room-and-pillar underground structure,the case study was carried out. In the case study, shape of rock pillar and room was mainly considered. From the analysis,a displacement at the roof, the maximum principle stress and plastic state were examined. To optimize variables in the casestudy, cases from the Seoul metro station were analyzed, then a target depth of the underground structure and groundconditions were determined. And the height of rock pillar and room were chosen from the assumed purpose of undergroundspace, i.e. living/office and warehouse. Total cases of analysis was 180 cases including 3 types of ground condition, 5 typesof rock pillar and 6 types of roof span. It is expected that results from analysis can be used to determine the installation ofsupport in room-and-pillar underground structure with stability, utilization efficiency of underground space andapplicability of vehicles.
