  • Last 1970's Korea opened the Kyoung-bu highways from Seoul to Pusan, and Korea government had change the transportation policy to focusing on the road and motors. but 1990's Korea had been the heavily traffic jam in long distant transportation system and logistics. That's why Korea government studied on feasibility survey of High-speed train. As the KTX opens, traffic networks covering large areas In Kyeongbu-line (Seoul- Daejeon- Busan) are expected to raise synergy effects in economics as well as in korean culture respects. Having been playing an important transportation role in Korea for the last 106 years. With opening of the high speed railway, KORAIL in inevitable to make a drastic reform. To achieve this purpose, it is necessary that KORAIL has to be small and effective streamlined organization. In should increase traffic capacity by improving infra facilities. It need to also expand its internal functions by connecting the KTX with the conventional railroad system.

  • Quite a few of persons often fall into an error that ISO has happened an additional work at construction sites. Supervision works, however, are carried out in compliance with 'Guidelines for the Supervision Works' which is including most ISO Requirements. Additional requirements needed for the supervision works are not many. This study has studied on the ISO application of supervision works in relation to, 1) ISO 9001 & KS A 9001 Quality Management System Basic Model, 2) The Process of Railway Construction Work Supervision Quality Management Plan, 3) Supervision Work Performance Guide Book(2005) & KS A 9001(2001) Standard, at the railway construction sites.

  • Application of information technology for the construction area has been processed actively with the development of information technology. In this study, a framework of the Construction Specification IETM(Interactive Electronic Technical Manual) was suggested through the analysis of the Department of Defense(DoD)'s standards and the trend of techniques related to the IETM. As the Framework, the DFD(Data Flow Diagram) of the construction specification IETM's organizing and using procedure was suggested. And a Model of construction specification IETM was organized on the basis of DFD. Finally, a scenario was constructed by the pilot system which is based on the model. The application of the construction specification IETM would make efficient and effect task implementations possible. By that, in addition to the reduction of the cost and time, the quality enhancement from information missing protect effectiveness could be expected.

  • This study aims to examine the influence of the Daegu Subway Line 3 construction on apartment price fluctuation and to find the factors causing the apartment price fluctuation in the station area of the Daegu Subway Line 3. Empirical results of this study are as follows: first, the apartment price is more fluctuated or increased at the time of completion of subway construction than at the time of breaking ground; second, the opening of the Daegu Subway Line 3 has positive impact on apartment price nearby the station area of the Daegu Subway Line 3, especially apartment prices in the second station area (200-600m) are positively related to the opening of the Daegu Subway Line 3; third, medium-large size ($85-135m^2$) and large size (excess of $135m^2$) apartment are sensitively related to the apartment price fluctuation by the Daegu Subway Line 3 construction; and fourth, Buk-gu and Suseong-gu areas are the main beneficiaries. The results of this study suggest implications for tax and redistribution policies in the station areas.

  • Recently, due to adjacent excavation work such as new buildings and common tunnel expansion concentrated around the urban railway, deformation of the underground box and tunnel structure of the urban railway built underground has occurred, and as a result, repair and reinforcement work is frequently carried. In addition, the subway is responsible for large-scale transportation, so ensuring the safety and drivability of underground structures is very important. Accordingly, an automated measurement system is being introduced to manage the safety of underground box structures. However, there is no analysis of structural damage vulnerabilities caused by subsidence or uplift of underground box structures. In this study, we aim to analyze damage vulnerabilities for safety monitoring of underground box structures. In addition, we intend to analyze major core monitoring locations by modeling underground box structures through numerical analysis. Therefore, we would like to suggest sensor installation locations and damage vulnerable areas for safety monitoring of underground box structures in the future.

  • It proceed the trial test by applying blasting system with combination of electronic detonator and non-electric detonator(Supex Blasting Method) for the purpose of preventing the over-break as well as controling the blasting vibration and noisy at the site of Boseong-Imseongri railroad section ${\bigcirc}{\bigcirc}$. As a result of that, the blasting vibration and noisy was measured within the allowable standard of vibration. In conclusion, the combination of electronic detonator and non-electric detonator can not only reduce come construction cost, level of vibration and noisy but also get the prevention effect for Public resentment and minimize the rock-damage through over break control.

  • This paper describes a study on the permeability reduction of the riverbed ground during urban railway tunnel construction. The research is mainly concentrated on the study of the grouting or injection methods among permeability reduction methods which can be adapted in the riverbed ground. The design technology of grouting methods considering the long term hydro-geological behaviour in the riverbed, was suggested. Two injection methods namely, Natural Durable Stabilizer (N.D.S) and Space-Multi Injection Grouting (S.M.I) methods, were introduced as new approach methods which could be adapted to modify the riverbed ground. In order to evaluate the performance of the improved ground by the N.D.S and S.M.I method, a series of pilot tests including the field and laboratory permeability tests, were carried out in the river crossing tunnel construction sites. The results obtained from pilot test program, were also reviewed. The results, the grouting efficiency of the S.M.I method using the non-alkalimeter silica sol is better than that of N.D.S method using cement. In addition, it is anticipated that the current research results are contributed to develop the grouting design technology.
