  • This study evaluated the economic aspect of the rainwater harvesting facilities by hydrologically analyzing the inflow, rainwater consumption, rainfall loss, tank storage, and overflow time series to derive the net rainwater consumption and the number of days of rainwater available. This study considers several rainwater harvesting facilities in Seoul National University, Korea Institute of Construction Technology and Daejon World Cup Stadium and the results derived are as follows. (1) Increasing the water consumption decreases the number of days of rainwater available. (2) Due to the climate in Korea, a larger tank storage does not increase the amount and the number of days of water consumption during wet season (June to September), but a little in October. (3) Economic evaluation of the rainwater harvesting facilities considered in this study shows no net benefit (private benefit). (5) Flood reduction effect of rainwater harvesting facilities was estimated very small to be about 1% even in the case that 10% of all the basin is used as the rainwater collecting area.

  • The safety of LPG vessel storage has been simply designed and controled with blast wave barrier structure concept regardless of its quantity or hazardous situation. The limit of regal controls on LPG vessel storage need to be identified in terms of safety buffer distance from LPG explosion. The level of overpressure effect and heat radiation to the neighbouring structure and human activity required to be estimated to find the gap between existing controls on such storage. PHAST and IAEA manual for risk rankings and assessment had been applied to get the required safety distance for neighbouring facilities, Japanese legal control for such facilities were also investigated. To this context the issues on LPG vessel storage required additional safety distance between existing blast wave barrier structure and safety separation distances.

  • Recently, expansion of urban and social infrastructures is planned to go through the transfer of military facilities or crossing the infrastructures via underground tunnels. However, when crossing facilities such as ammunition and explosive storages, a high level of safety assessment is required to prevent an accidental explosion of ground ammunition. In this study, a case study was conducted to evaluate the effect of blasting for the construction of tunnel on the ground ammunition facilities. The design section of Sinansan train operated by the Korea Railroad Authority with agreement of the Ministry of National Defense was selected. For the purpose of this study, the vibration velocity due to explosion was predicted by using GTS-NX, a numerical analysis program. Through literature review, it was confirmed that the vibration velocity of 0.2cm/sec can be a safety evaluation standard. These safety evaluation indicators and procedures used in this study can be utilized as an index of safety evaluation in the planning of social infrastructures that cross the ammunition facilities in the future.

  • As consumption rate of energy increase rapidly, the facilities of fuel storage tank become large size. Almost all of the industry or public facilities storing fuel in underground fuel storage tank is manufactured by steel materials. Thus, this fuel storage tank made of steel materials is damaged by stray-current corrosion, it become destruction. If fuel storage tank is destructed, petroleum, oil and gas are leaked. So it bring about environmental pollution, energy loss, fire and explosion. Therefor, in this study, for study on the prevention of corrosion damage in underground fuel storage tank, it were investigated by corrosion and stray-current corrosion for SS 400 in dry sea sand and wet sea sand along to specific resistance. The main results obtained are as follows : As specific resistance decrease in wet sea sand, corrosion rate per year increase linearly, in case of back fill up wet sea sand in underground fuel storage tank, if the water is flow into dry sea sand, corrosion tendency of underground fuel storage tank is supposed sensitive.
