... Abstract: We are conducting a small-scale CO 2 injection demonstration project in offshore Pohang Basin, SE Korea to test various techniques related to CO 2 sequestration, which include reservoir characterization and modelling, drilling and completion, and monitoring systems. The target...

... through detailed geological survey and variations of discontinuities and rock blocks should be utilized. 1. INTRODUCTION Most of Korea consists of mountainous topography, and thus artificial slopes have continuously been produced during the construction of infrastructures such as roads and railways...

... ABSTRACT: Since late in the 90''s, in-situ rock stress tests have been widely conducted to provide the quantitative information on the stress state of an engineering site at the design stage of an underground rock structure in the Kyungsang Basin, Korea. Totally, 270 in-situ stress...

... that roads and highways are the most important infrastructures since they are used in the transportation of people and goods. KICT (Korea Institute of Construction Technology) and the MLTM (Ministry of Land, Transport and Maritime) has developed and operated the CSMS since December 1997 in order to maintain...

... and shale. In particular, a reddish shale layer is a fractured zone and the upper part of this reddish shale layer shows bulging and tensile cracks. We estimated kinetic displacements and safety factor for the two slopes using MIDAS/GTS based on finite element analyses. 1. CRETACEOUS ROCKS OF KOREA...

... ABSTRACT: Korea has tunnels of approximately 1,843km in total length that are already completed or under constructions. The total number of tunnels in 1997 was 184 and reached to 932 in 2006, and it has increased by 750% for last 10 years. The number of tunnels longer than 500m was 52...

...1. INTRODUCTION A number of abandoned mines exist in many countries as well as in Korea. In UK, more than 70,000 old mine workings are reported and some of them may be three centuries old [1]. In the USA, 354 subsidence incidents were reported over Pittsburgh Coal bed, most of which in the form...

...1. INTRODUCTION The Korea Atomic Energy Research Institute (KAERI) is developing a disposal system for the permanent disposal of the spent fuel generated from 19 nuclear power plants in Korea. In order to develop a reasonable disposal system, it is necessary to validate the system in a rock similar...

... ABSTRACT : Rockfall protection fences are used for diminishing rockfall damage in roads. In order to construct the fences in effective way, the conditions of rock slopes and total impact energy of rock slope should be considered. However, in Korea, the fences have been constructed without any...

... ABSTRACT: A landslide survey of more than 1,600 slides was performed at scales of 1:50,000 and 1:5,000 in Gyeonggi province, Korea. Although most of the landslides are classified as debris flows, the slides are translational at their triggering positions, On the basis of the field survey...
