Engineering geological studies were conducted for igneous rocks in southeast Korean peninsula. The purpose of the study is to establish zoning in view of engineering geology in ground construction. For engineering geological implication, lithology, lineament structure and discontinuities were surveyed and analysed. Using constructed data, We compared geological and engineering geological characteristics and made out the detailed engineering geological map. The map responses engineering characteristics such as weathering degrees, discontinuity systems of different rock types.

지질도 및 지질주제도들은 자원개발, 사회간접시설, 환경보전, 보건, 국방, 학술 및 교육 등 다양한 용도로 활용되고 있으며, 경제, 사회적으로 다양한 편익을 유발하고 있다. 본 연구에서는 AHP(Analytic Hierarchy Process) 방법을 통해 지질도 및 주제도의 가치를 구성하는 요소를 검토, 분석하여 각 요소별 중요도의 계량적 결과를 제시하였다. 분석 결과 신뢰성이 가지는 가치의 비중이 50% 이상으로 가장 높게 나타났으며, 편리성과 파급성은 $16%{\sim}30%$ 정도의 중요도를 가지는 것으로 나타났다. 하위 속성은 대부분의 경우에서 측정 정보의 정확성이 차지하는 비중이 가장 높은 것으로 분석되었다. 한편, 지질도 및 주제도 사용량의 경우 대축척 도면의 사용량이 상대적으로 크게 증가할 것으로 나타났다.

To develope SOC(social overhead capita) which constructs the railroad, highway etc., the geo-technical foundation have to be well understood for the safety works. In this paper, we selected Moonkyung area for the study area, which has various geological units and geological structure including the big thrust and fold. By this reason one of the geo-technical information is the engineering geology map. To make the map, lithology and soil distribution with drilling data are important elements. Three dimensional geo-infomation is established by fence diagram which is several geological cross sections and/or computer software 3D Geomodeller, EarthVision, GSI3D, Gocad.

Landslides are one of the natural disasters that cause a lot of financial and human losses every year It will be all over the world. China, especially. The Mainland China can be divided into 12 zones, including 4 high susceptibility zones, 7 medium susceptibility zones and 1 low susceptibility zone, according to landslide proneness. Climate and physiography are always at risk of landslides. The purpose of this research is to prepare a landslide hazard map using the Hierarchical Analysis Process method. In the GIS environment, it is in a part of China watershed. In order to prepare a landslide hazard map, first with Field studies, a distribution map of landslides in the area and then a map of factors affecting landslides were prepared. In the next stage, the factors are prioritized using expert opinion and hierarchical analysis process and nine factors including height, slope, slope direction, geological units, land use, distance from Waterway, distance from the road, distance from the fault and rainfall map were selected as effective factors. Then Landslide risk zoning in the region was done using the hierarchical analysis process model. The results showed that the three factors of geological units, distance from the road and slope are the most important have had an effect on the occurrence of landslides in the region, while the two factors of fault and rainfall have the least effect The landslide occurred in the region.

공학지질도(Engineering geology map)는 토목공사의 예비단계에서 필요한 지질자료를 도면에 표시하여 지질공학 계획(Engineering geological plan)의 수립과 토목설계 정보를 제공 위하여 작성하는 특수지질도이다. (Report by the geological society engineering group working party, 1972). 공학지질도에는 지질공학, 토목 또는 건축 기술자들이 필요로 하는 지질정보를 수록하기 때문에 기존의 지질도(Geological map)와는 다르게 작성한다. 즉, 지질도는 암석의 광물조성, 석기 (texture), 층서, 지질구조 등의 지질학적 분석을 통하여 지각의 생성 메카니즘과 지구의 역사를 규명하는 것이 궁극적 작성 목표이다. 따라서 지질도에는 공학기술자들이 필요로 하는 암석과 토층의 물리적/공학적 특성이나 지하수에 대한 정량적 정보 등이 수록되지 않을 뿐 아니라 공학기술자들에게 필요한 인간 생활권 부분인 지표와 천부의 지질학적 특성이 제외되는 경우가 많다.

In this study, the city of Osijek is used as a case study area for low to medium seismicity regions with deep soil over deep geological deposits to determine horizontal PGA values. For this reason, we propose new regional attenuation equations for PGA that can simultaneously capture the effects of deep geology and local soil conditions. A micro-zoning map for the city of Osijek is constructed using the derived empirical scaling equations and compared to all prior seismic hazard estimates for the same area. The findings suggest that the deep soil atop deep geological sediments results in PGA values that are only 6 percent larger than those reported at rock soil sites atop geological rocks. Given the rarity of ground motion records for deep soils atop deep geological layers around the world, we believe this case study is a start toward defining more reliable PGA estimates for similar areas.

산사태가 일어날 지점을 예측한다든지 사태물질로 인한 피해 예상지역을 알아내는 것은 쉬운 일이 아니다. 이는 산사태를 발생시키는 요인들이 여러가지가 있고 개개의 요인들이 산사태를 발생시키는데 기여하는 중요도도 서로 다르기 때문이다. 그러나 많은 산사태자료에 대한 분석을 바탕으로 발생 메커니즘 규명과 통계적 해석기법을 통해 산사태 발생가능성의 예측과 위험지역의 분류가 가능해졌다. 석조문화재가 산사면 또는 그 직하부에 인접해 있는 경우는 산사태가 발생되면 재해에 무방비로 노출되어 있다. 이 연구에서는 여름철의 집중호우 등에 의해 석조문화재 및 그 주변지역에 산사태가 발생할 가능성을 사전에 예측함으로써 그로 인한 석조문화재의 피해가능성을 분석하고자 하였다. 이러한 목적을 위해 2002년 8월 산사태재해로 인해 피해가 발생된 바 있으며 중요 석조문화재가 위치해 있는 실상사 백장암지역을 연구대상지역으로 선정하여 산사태 예측도를 작성하였다. 그리고 산사태재해 가능성을 발생확률로 표현하여 등급별로 구분함으로써 석조문화재 및 그 주변지역이 산사태에 취약한지의 여부를 평가하였다. 또한, 이러한 조사 및 해석기법을 앞으로 석조문화재 주변의 산사태재해 예측 및 평가를 위해 실용적으로 활용할 수 있는 토대를 마련하였다.

Most mineral resources are located in subsurface but mineral exploration starts with a step of investigation in wide-area to find evidence of buried ores. Conventional technique for exploration on wide-area as a preliminary survey is an observation using naked eyes by geologist or chemical analysis using lots of samples obtained from target area. Hyperspectral remote sensing can overcome those subjective and time consuming survey and can produce mineral resources distribution map. Precise resource map requires information of mineral distribution in a subpixellevel because mineral is distributed as rock components or narrow veins. But most hyperspectral data is composed of pixels of several meters or more than ten meters scale. We reviewed subpixel unmixing algorithms which have been used for geological field and tested detection ability with Hyperion imagery, geological map and seven spectral curves of mineral and rock specimens which were obtained from study areas.

As a part of natural hazard assessment, regional slope stability analysis was conducted using Geoscientific Information System (GIS) in the northern area of Chungju Lake. Selected factors which affect the slope stability in the study area were lithology, soil, density of lineament, groundwater level, dip of slope, aspect of slope, and geological engineering properties. Geological structural domains were determined by collected data of joint orientation from about 200 sites in order to produce a slope instability map. Potential type of failure and its direction could be expected through the domains. And a slope instability map was produced, comparing the representative orientations of the domains with the orientations of the slopes which were made through TIN module in ARC/INFO. Under the consideration of environmental geological characteristics of the study area, rating and weighting of each factor of slope stability analysis were decided and spatial analysis of regional slope stability was couducted through overlaying technique of GIS. The result of areal distribution of slope stability showed that the most unstable area was the area between Mt. Pudae and Mt. Jubong, and the northern area of the railway station, Samtan.
