  • With the tunnel to case of the construction slope it executes the periodic maintenance due to an objectivity standard. But, the standard connected with construction slope is not integrated with the important public paper organic enemy and it is duplicated and the standards which conflict are being scattered. Also, it is referred to some specifications simply and the feature which is diffuse appears. Therefore, there is a necessity which it investigates the problem point of the maintenance civil official and it improves rationally and it takes a triangular position a confusedly be standard system. In this research which it sees accomplished the fundamental research against the inspection item classified by reinforcement method for the construction slope maintenance.

  • Inventory survey is process collecting data about cut slope. It's different from inspection. It contains not only basic information about cut slope, especially location, GPS positioning, height, length, weathering, joint direction, water conditions but also level of danger and damage. Collected data are being used get at status about cut slope along national roads. And It helps judging about priority of detailed investigation. According to results of analysis, we found better method about maintenance of cut slope. Later on, if inventory research is finished, we will understand characteristics of collapse slopes.

  • Developed is a new environment-friendly concrete-block retaining wall system. The conventional analysis methods are not directly applicable because the proposed concrete-block wall system is made of by interlocking the blocks with shear keys. Therefore, the shear analysis as well as stability analysis have been conducted to secure the safety of block-wall system. Overall slope stability analysis was also performed. An appropriate strengthening method was developed to ensure the safety when the block-wall system is relatively high. The method of analysis for strengthening the concrete-block wall system was also proposed. The proposed environment-friendly concrete block retaining wall system shows reasonable safety and can be a good construction method for retaining walls and river bank walls.

  • Blasting is a technique for rock excavation: For instance, a rock cutting in a mountain side to prepare a base for a road. The blasting damage affect the rock slope stability. Therefore control blasting must be used. In this study, cutting cases of Sixty-nine rock blasts were investigated. Blasting damage patterns in rock slope and reinforcement methods are studied.

  • This study area show the complicated geological figure and some developed small fault area in southern of Korea. Because of insufficient investigation and design for the big slope, even the safety analysis by the specific institution, in the event, there were 6 times failure and 6 time safety analysis. After all, The height and remedial work cost of the slope became much bigger then early stage.

  • 최근 기후변화로 인한 폭우가 빈번하여 사면붕괴가 많이 발생하고 있으며, 이에 따른 인명과 재산피해가 해마다 증가하고 있는 추세이다. 사면붕괴는 사전에 붕괴원인을 찾아 이 원인을 제거하여 예방조치를 하는 것이 가장 바람직한 방법이며, 예방적 차원, 원인 규명, 복구 대책으로서 사면 안전진단을 시행하게 된다. 따라서 본 연구에서는 안전진단 대상사면에 대하여 수많은 점군 데이타로 정밀한 지형정보를 단시간에 취득하는 LiDAR를 활용한 결과 다음과 같은 결론을 얻었다. 첫째, 대상구역에 검사점을 설치하고 오차크기를 분석한 결과 수평위치오차의 RMSE는 ${\pm}2.2cm$, 수직위치오차의 RMSE는 ${\pm}3.0cm$로써, 실용적으로 양호한 결과를 얻었다. 둘째, 경제성이 아주 우수하고, 정확한 지형자료 취득이 가능하다. 셋째, 한번 스캔한 구역은 임의의 단면도를 짧은 시간에 정확하게 취득할 수 있어 전문가가 위험단면 검출에 편리하다.

  • The facility diagnosis technique of past subjective judged the technical expert and interpreted stably mainly. The facility the periodical civil official becomes indispensability consequently with the law and the system and objectivity inspection which relates with a this and development of diagnosis technique were necessary. Currently the evaluation elements which relate with an inspection and diagnosis technique depended to the subjectivity of each facility quality, data statistics, diagnosis know-how, various circumstance and the technical expert and the evaluation item came to decide. But the evaluation score distribution of marks of each item depended plentifully in data analysis result and experience. The past method is weak in logically because the objection theoretical background and basis are insufficiency. Consequently in order to apply a data analysis result and an experience logically, it used AHP(Analytic Hierarchy Process) method from this research. It is visible with the fact that the application result reconfirmation and complement process will be necessary the technique which is suitable in the multi facility management. Also it is expected with the fact that the application characteristic from the next relation technique will be excellent.

  • As the variability of recent rainfall is increasing, it is becoming important to recognize the possibility of changes in the current reservoir state in advance and to inspect the stability based on accurate evaluation standards. However, the evaluation standards for the state change factors of reservoirs are still not suitable for agricultural reservoirs and thus much improvement is needed. Therefore, in this study, the evaluation criteria for state change factors specialized for small reservoirs were categorized and standards were prepared by considering factors that may cause state changes on the dam crest, upstream slope, and downstream slope of the embankment. The categorized results were configured based on the number of mentions of the precision safety inspection report on major defects in 102 reservoirs and the defect factors found in field investigations. The findings of the study indicated that the current state change standards require many revisions for excessive or unnecessary state change factors in the reservoir. Specifically, the deletion of measurement gauges not applicable to the reservoir, the addition of defects found in the reservoir, and the scope of use of the term were proposed. The results of this study can contribute to efficient system operation and management by improving the deficiencies in the system and introducing a new state change factor.

  • Korea is topographically and meteorologically prone to natural disasters. In addition to extraordinary weather, localized heavy rain is a irregular occurrence. Korea are frequently damaged by rain, wind, flood, etc. Recently, slope failures are disastrous when they occur in mountainous area adjoining highways. The accidents associated with slope failures have increased due to rapid urbanization of mountainous area. Therefore, the inspection of slope is conducted to maintain highway safety as well as road function. We developed basic function and risk management of a partial shape on highway slopes based on the internet. It is important for quantitative risk evaluation of highway slopes.
