This study is about development of personal disaster shelters for minimization of the casualties caused by the landslide and steep slope collapse. The objectives of present research is the selection of disaster evacuation facilities utilizing FRP (Fiber Reinforced Plastic) material. For the proper assessment of FRP member, several layers by strength test and the three-dimensional numerical analysis of these FRR member was carried out. As a result, the personal disaster evacuation facility utilizing FRP materials, was found to be of a material that is able to protect the weak person at the time of the collapse of the landslides and steep slopes.

The houses are formed in the lower part of the mountain slope face in most agricultural areas of Korea, and old residents accounting for a large portion of the agricultural populations cannot respond to the evacuation quickly when the landslide happens, and the possibility the life damage occurs is high. Therefore, it is urgent to arrange the measure on this. This study is intended to develop the personal disaster evacuation apparatus that can be installed in the house to minimize the life damage by the landslide and to develop the self-initiative evacuation apparatus. This study suggested the load applicable to the personal disaster evacuation apparatus by quantitatively analyzing the effect of the load of rockslides and avalanches caused by the landslide on the structure. Also, the material property of materials was calculated through the tension and bending intensity test after making the specimen of glass fiber reinforced plastic (GFRP) member. The load weight and material property drawn from this study can be used as the basic material for the stability analysis of the personal disaster evacuation apparatus.

Recently, lots of damages have been lost because large magnitude earthquakes were occurred in the world. It has been increased the number of earthquakes in Korea. It needs improvement required for the repair of deteriorated reservoirs, reinforcement and raised reservoir coping with climate change and earthquake. This study aims to investigate the seismic behavior of deterioration reservoir levee using dynamic centrifugal model test. Therefore, two case tests in centrifugal field of 60 g, the result has provided the influence on the acceleration response, displacement, settlement and the pore water pressure of the reservoir with earthquakes. From the results larger displacement and acceleration response at the front side of reservoir embankment with poor-fabricated core in seismic condition may degrade overall stability. Reasonable reinforcement method of the raised reservoir embankment is required for ensuring long-term stability on earthquake.

It is significant to redevelop the deterioration reservoir through raising for countermeasure to climate change and Earthquake improvement of reservoir. This study aims to investigate the behavior of deterioration reservoir with poor-fabricated core subjected to raising water level and earthquake using numerical analysis. From the analysis results, water level raising and earthquakes induce crack and subsidences at the crown and the front side of deterioration reservoir. For the reinforcement of the deterioration reservoir is required appropriate measures method and raised method suitable, drainage and slope protection method judged to be necessary.

최근 들어 인구의 증가와 산업화 과정 및 도시화 등이 진행되고, 이에 따른 토목 및 건축 기술의 발달로 인하여 대도시의 인구밀집지역에 대규모 지반굴착공사가 빈번히 수행되고 있다. 특히 최근 대도시의 지반굴착공사는 한정된 토지의 이용을 극대화하기 위하여 기존 시설물과 인접하여 대규모 연직 지반굴착 또는 터널 굴착공사가 주를 이루고 있다. 이러한 도심지에서의 굴착공사에 따라 지반 및 터널굴착에 따른 공사현장의 피해 등 많은 문제점들이 야기되고 있으며, 특히 지하공동으로 인한 도로 함몰과 지반 침하 등 지반 관련 재난 사고가 빈발하고 있어 중요한 사회적 이슈로 등장하고 있으며, 이에 따른 사회적·경제적 손실이 발생하고 있다. 따라서, 본 연구에서는 지하공동에 의한 지반거동을 수치해석을 통해 검토하였으며, 이로부터 획득된 결과를 분석함으로써 지반침하 거동을 예측하였다. 본 연구의 결과물은 향후 도심지 지반재해 평가기준 정립을 위한 기초자료로 활용할 수 있을 것으로 기대된다.
