Recently, as ‘ground subsidence in urban area’ problem become social issue, Central & Local Government examined current state of ground subsidence. As a results, It is revealed that 1)sewage pipeline damage, 2)excavation work of surrounding pipeline, and 3)water pipeline damage were main reason of subsidence. This study is going to present weak-point for each type of pipeline in the case of water pipeline monitoring, by analyzing current state materials of water pipeline leakage work of ○○city, to prevent ground subsidence from water pipeline leakage.

Bridge decks are rapidly deteriorated by various environmental effects such as heavy vehicle and deicing salt, etc. For bridge owners in Korea, therefore, it is important to understand the defect characteristics and causes of deterioration of bridge decks as well as to predict the future need for bridge deck replacement based on proper deterioration models.
Finding a solution to the problem, in this research, the site investigation for 76 domestic old bridges were undertaken and deterioration models of bridge decks were proposed by analysing service year-condition index relationships of more than 500 bridges.

Ministry of Land, Infrastructure and Transport(MOLIT) publishes Yearbook of Road Bridge and Tunnel Statistics once every year. Also, Korea Institute of Civil Engineering and Building Technology(KICT) is operating the website based on GIS to provide the status information of bridges and tunnels on the road. In this paper introduces road Bridge and Tunnel Information(BTI) system that offers the base data for the effective maintenance of bridges and tunnels on the road.

Since the ground subsidence frequently occurs caused by water and sewage pipeline leakage, this paper reviews current maintenance management regulation, legislation related to water and sewage pipeline measurement for maintenance in practice to prevent and manage this phenomenon. Analysis of current system shows the difficulty of ground subsidence evaluation and importance of the law which is now being established has been emerged. In addition, it is determined that the regulation contains specified content with specific range of water and sewage pipeline is required for its maintenance.

Recently, Advanced water treatment facilities with Ozone are being introduced domestically. However, waterproofing/corrosion prevention construction method of concrete structure for existing advanced water treatment makes waterproofing/corrosion prevention materials and concrete deteriorated because of strong oxidation of ozone. Therefore, in this study, using a metal spraying system was evaluated for bond strength between concrete and metal spraying coating.

Concrete shrinkage is happened due to the cement hydration and water evaporation from early ages, and it induces crack of concrete. In this study, the crack resistance of fiber reinforced concrete was compared with fiber type and fiber volume fraction. From the results, cracking is delayed when the volume fraction is increased. And, crack resistance is improved regardless of fiber type.

This research investigated the effects of matrix strength on the direct tensile behavior of high performance hybrid fiber reinforced cementitious composites (HPHFRCCs) at high strain rates. 3 different type matrixes were used (56 MPa, 81 MPa and 180 MPa). And macro fiber was long hooked fiber (H, =0.3 mm,=30 mm) and micro fiber was short smooth fiber (S, =0.2 mm, =13 mm). The volume content of macro fibers was 1.0% and the volume content of micro fibers was 1.0%. The high matrix strength clearly increased the tensile strength and peak toughness of HPHFRCCs even at high strain rates (74 ~ 161 /sec).

This paper presents a comprehensive probabilistic model of reinforcement corrosion initiation under the combned action of carbonation and chloride ingress. The numerical results show that the probability of reinforcement corrosion initiation under the combined action is much higher than the case of only considering the action of single factor.

Conventional strain gauge can measure about 15~20% elongation. However, when the steel are ruptured, the strain at the necking region can be much higher than the measurement capacity of the conventional strain gauge. To measure the maximum strain at the necking region a new measurement technique should be developed. In this study, for this purpose image processing method for measuring 2-D strain distribution of tensile specimen of steel is proposed.

This paper presents the quantitative evaluation of migration diffusion coefficient considering an effect of cold joint. This also contains an effect of mineral admixture on chloride diffusion coefficient and the interaction of cold joint for chloride diffusion is experimentally investigated. The effect of mineral admixture is very effective to resistance to chloride penetration even if concrete has cold joint section.

This paper presents an quantitative evaluation of loading conditions and its interaction of cold joint on accelerated diffusion coefficient. For the work, various loading conditions are prepared for concrete with cold joint. The mineral admixture of GGBFS (Ground Granulated Blast Furnace Slag) is replaced with 40% of weight ratio. The effect of GGBFS is evaluated to be effective to hinderance of chloride penetration. The compressive loading effect shows rapid enlargement of chloride diffusion after 60% of loading ratio while the tensile loading effect shows initially increased diffusion.
