Abstract

This study proposed the aseismic design concept for underground space based on site response analysis and laboratory tests. The results of this study showed that the location of the control points of input motions such as design response spectra and time history of acceleration and the assumption of bedrock properties such as elasticity or rigidity play an important role in aseismic design of underground space. Therefore, the appropriate ground response model among models applying motions such as free surface motion, bedrock motion, or bedrock outcropping motion must be utilized to provide reasonable boundary conditions of underground space under earthquake loading and practical aseismic design.

본 논문은 부지응답해석 및 실내시험에 기초한 지하공간 내진설계 개념을 제안하는데 목적을 두고 있다. 설계응답 스펙트럼 및 가속도시간이력과 같은 입력운동의 통제점 위치와 기반암 가정물성이 내진설계에 매우 중요한 역할을 하고 있음을 본 연구결과를 통해 알 수 있었다. 그러므로 통제점 위치에 따른 지표면 자유장운동, 기반암운동 또는 암반노두운동 같은 지반운동 변화를 합리적으로 모델링 할 수 있는 적절한 지반응답 모델을 이용하면 지진하중을 받는 지하공간의 합리적인 경계조건을 모사할 수 있고 현실적인 내진설계가 가능하다.
