  • 정보통신분야의 책임감리를 정착하기 위해서는 관련법 정비가 시급히 이뤄져야 한다. 특히 복합건설공사의 경우 해당사업의 관련법이 혼재돼 있고 이에 대한 해석의 차이로 각종 간섭사항이 나타나고 있으며 이로 인한 감리업무 혼선이 초래되고 있다. 본 연구에서는 정보 인프라 구축을 위한 정보통신설비 공사의 설계 및 감리를 위한 제도개선 방안을 건설기술관리법, 전력 기술관리법 등의 관련법규와 정보통신공사업법을 비교하고, 선진국의 사례를 조사하여 제도 개선 방향, 즉 정보통신분야의 설계감리의 필요성, 책임감리제의 도입, 및 감리원 관리의 체계화 방안 등을 제안한다.

  • Recently, the limit state design method in the design of the structure is in global trend, but it is limited to a few structures in Korea. Since the introduction of the limit state design method has recently been attempted for tunnels, which are the main underground structures, it is surely necessary to understand the latest limit state design method. Therefore, based on the recently published AASHTO LRFD Road Tunnel Design and Construction Guide Specification (2017), structural load factors and load combinations were reviewed, and various factors which should be applied for the review of structures have been analyzed. In this study, utility tunnel section and subway tunnel sections used in Korea were analyzed by the limit state design method, and we have analyzed the direction of application of limit state design method through studying the tendency of member force by various influential factors such as ground conditions, load modifier and joint stiffness.

  • In many countries including Korea, the design concept of pavement structure has been converted from empirical method to mechanisticempirical method since the advent of compaction control based on resilient modulus proposed by AASHTO in 1986. Studies of last decades indicates that the classical compaction control method based on relative compaction and plate bearing test(PBT) will necessarily move to the methods taking advantage of light falling weight deflectometer(LFWD) and dynamic cone penetrometer(DCP) in addition to PBT. In this study, the validity of resilient modulus prediction equation proposed by Korean Pavement Design Guide is verified by comparison with physical properties of subgrade soil and the results of structural analysis. In addition, correlational equations between elastic modulus measured by various field tests and resilient modulus estimated by empirical model are proposed. Finally, a field test-based compaction control procedure for subgrade is suggested by using proposed correlational equations.
