$\lceil$The Construction Technology Development Master Plan$\rfloor$ aimed to promote construction technology R&D and to use its result efficiently is a legal plan based on Construction Technology and Management Law and established every five years. Now $\lceil$The 3th Construction Technology Development Master Plan(The 3th Master Plan)$\rfloor$ is establishing by MOCT(Ministry of Construction & Transportation) because the 2th Master Plan is completed at 2002. The 3th Master Plan suggests 'Establishment of construction environment leading the world-wide construction market' as a long-term vision, and also presents basic targets ; 'Improvement of competitiveness through conducting construction project efficiently', 'Transform into technology-oriented industry'. It consists of 7 fields and 25 main subjects. The 7 fields are construction manpower, production system, environment, safety, construction information, construction engineering, construction R&D.

Construction and Transportation R&D budget is increased every year. Therefore, outcome is important issue. Also, we must try for practical use of outcome. And we need strategy for practical use of outcome. This is research for the application of research and development outcome. Specially, this research studies about way for construction standard. And this proposes a institutional improvement. First, it catch a problem point with present condition analysis. Second, It executes a survey and analysis. Finally it presents some policy suggestion. This research solves two problems. This applies to the field of research and development outcome. Another this amend construction standard.

격심한 세계적 사회환경의 변화는 모든 산업분야에서 기존의 패턴을 탈피해 새로운 패러다임으로의 전환을 요구하고 있다. 이를 어느 정도 충실히 반영해 혁신을 이룰 수 있는가가 흥망을 좌우하는 중요한 요체가 되었다. 건설 기술의 R&D 분야는 기술경쟁력 강화를 위해 필수적인 요소로 미래에 대한 투자이자 혁신을 이끄는 연구 성과물을 내놓고 있다. 고부가가치 및 미래 신성장 동력 창출을 위해서는 전적으로 R&D 분야에 의존할 수밖에 없다. 본지는 지난호부터 기계 설비분야에서 새로운 재료 및 기술 등을 연구 개발하고 실용화에 힘쓰는 연구원들을 만나 연구현황 및 향후계획 등을 소개하고 있다.

The use of roadheaders has been increasing to mitigate the problems of noise and vibration during tunneling operations in urban area. Since lack of experience of roadheader for hard rock, the selection of appropriate machines and the evaluation of cutting rates have been challenging. Currently, empirical models developed overseas are commonly used to evaluate cutting rates, but their effectiveness has not been verified for domestic rocks. In this paper, a comprehensive literature review was conducted to assess the rock cutting force, cutterhead capacity, and cutting rate to select the appropriate machine and evaluate its performance. The cutterhead capacity was reviewed based on the literature results for the site. Furthermore, a new empirical model and simplified method for predicting cutting rates were proposed through data analysis in relation to operation time and rock strength, and compared with those of the conventional model from the manufacturer. The results show good agreement for high strength range upper 80 MPa of uniaxial compressive strength.
