dc.description.abstract국내 터널 갱구사면에 안정성을 확보하기 위한 사면보강은 앵커, 쏘일네일 및 록볼트 등을 이용한 다양한 공법이 사용되고있다. 갱구 사면보강공법 및 보강재 배치, 보강재 길이 등을 선정하기 위해서는 시행착오법 등 시간이 많이 소요되기도 하며, 최적조건의 상태가 선정되었는지에 대한 검증이 쉽지 않은 경우도 발생한다. 본 연구에서는 FLAC3D 프로그램에 내장된 FISH 언어를사용해서, 차분진화 알고리즘(DEA)을 적용한 최적화기법을 개발하였다. 갱구사면 보강공법 중에 쏘일네일링 공법에 대한 데이터베이스를 구축한 후, FLAC3D 해석을 통한 안전율 기반의 최적보강배치 계획을 선정할 수 있도록 하였다. 수치해석 결과, 완전조합(FC)에비해서 DEA 기반의 최적화기법이 해석회수가 8배 정도 감소함을 확인하였다. 갱구 사면보강 설계 시 개발된 시스템을 활용하면, 최적보강배치 계획을 상대적으로 쉽게 선정할 수 있을 것으로 기대된다. In order to ensure the stability of tunnel portal slope, reinforcement method such as anchors, soil nails and rock bolts have been used in Korea. When selecting slope reinforcement methods in tunnel portal area such as reinforcement arrangement and length, trial and error method can be very time-consuming and it was also not easy to verify the selection of an optimum condition. In this study, using the FISH language embedded in the finite difference code FLAC3D program, the optimization technique was developed with the Differential Evolution Algorithm (DEA). After building a database on the soil nailing method in tunnel portal area, this system can be selected to an optimum arrangement plan based on the factor of safety through the FLAC3D analysis. Through the results of numerical analysis, it was confirmed that the number of analysis was decreased by about 8 times when DEA based optimization technique was used compared to the full combination (FC). In case of the design of slope reinforcement in tunnel portal area, if this built-system is used, it is expected that the selection of an optimum arrangement plan can be relatively easier.en_US
