In this study, propose a building Online system based on information sharing that minimizes the unnecessary expenses used to for the management of slope face-map newly created through new road, extension and linear improvement. Also, as a result of the economic feasibility analysis by quantitatively estimating the initial invest costs and the benefits resulting from the cost reduction, the B/C ratio is evaluated to be 1.0 or more after 2 years, be used to effective management plan.

Recently, assessment of vulnerability of existing dam structures is a rising key issue in aspects of entire life year from design, construction to maintenance even in Korea due to more frequent earthquakes and effects of climate change. This study aims to develop a vulnerability assessment method for existing dam structures by using fragility analysis method based on 2-D FEM analyses, which can take into consideration various uncertainty information to dam structure safety assessment, and which may be incorporated into an integrated safety management platform under development by K-water.

Recent earthquake events arising all over the world, cause serious damages to material/ human resources every year. South Korea, categorized to be relatively safe from earthquakes, recently became subject to frequent seismic events, which made it essential to prepare for damages caused by such events. Failure of hydraulic structures, such as dams, can cause serious damages to resources in the lower reaches of a river. In this study, Seismic stability evaluation was performed to determine the crest displacements of dam caused by the 40 earthquake waves recorded actually.
