  • 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.

  • Road Sink Phenomenon (RSP) is one of the major issues in South Korea. National and local governments are trying to develop effective preventive measures against the RSP. Developing the policy-oriented RSP management is most important to minimize possible losses induced by RSP. In this study, we employed the Futures Wheel (FW) method to derive influence factors for RSP management. FW method is widely used for predicting future social-environmental condition. In addition, RAND Corporation's method is used to derive potential strategic agenda based on derived influence factors by FW method. These derived strategic agenda can contribute to develop the policies related with RSP management.

  • The damage by Debrisflow is occurring repeatedly recently by influences of abnormal climate changes. To reduce damage of Debris flow, primarily establishes the suitable measures and apply, in order to do that it is important for investigate the actual condition of Debrisflow. However, it is difficult to understand the current situation of Debrisflow phenomenon because the limit of technical development. For the reduce damage by future Debrisflow, have to collect data, analysis and preservation base on real status of Debrisflow disasters. This paper will refer to The Proposal of Debrisflow Investigation development have been applied overseas to the The Proposal of Debrisflow Investigation which already proposed it at these papers with bases. And this paper will suggest currently face objective The Proposal of Debrisflow Investigation to be able to do utilization to a Debrisflow occurrence situation and state and further study analysis(2).

  • The bench of cut-slope is necessary to stabilizing. But it is possible to be a weak zone in slope. When a small scale failure is occurred in a bench, it influence a large scale failure of slope. So when it is found out any unstable factor, weathering of rock, a direction of joint in a bench, if the bench is reinforced suitably, the holly failure is prevented in cut-slope

  • Recently, disaster that is earthquake, sever rainstorm and the tidal wave were increased by abnormal weather. These influence which is the slope stability of the completed slope as well as under construction slope is affected by disaster. But the management standard for the construction slope is incomplete. Also, 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. In this research which it sees consequently the inside and outside of the country construction slope the maintenance civil official relation law and standard investigation it leads and the problem point and a improvement program of management criterion and to sleep the construction slope which is suitable in domestic actuality it prepares and propose.

  • The construction road work are increasing now. And the domestic slope construction are steadily increased and changed the complicated and large-scale. Therefore ground reinforcement for slope stabilization has been increasingly used during the past few decades with a wide variety of techniques including soil nailing, rock bolt, anchor and different types. But in some cases which applied slope reinforcement construction by badness or mistake. So this paper is the study of construction badness for slope reinforcement.

  • Cut slope and facility of management investigation is the protection of humans and properties. it is very important the prevention of disaster facility and the damage of the slope protection facility. It is very difficult to forecast slope stability, disaster possibility and collapse. It will be able to minimize the damage which it prepare against slope facility and cut slope of deformable investigation and collapse and the disaster. therefore those deformable investigation is important. Investigations execute upheaval, crack, sliding for slope and cut slope reinforcement. Investigation executes forecast in place where the construction problem, the effect which the damage in road traffic or the contiguity facility.

  • Falling rocks are classed by the collapse to wide meaning. it is a kinds of earth disaster that has happen every year. Falling rocks are defined as blocks which had fallen from the cliff. It is caused by the relaxation of discontinuous structures like as a joint, a foliation, a bedding, and so on. Usually, the Relaxation of blocks from the rock face is happened by various kinds factors that are acted as a complex. Sometimes, the tree can be a factor of the weakness or relaxation of rock blocks and a cause of the falling rock.

  • The purpose of this study was to utilize 90 construction site accidents accumulated from 15 years ago by the Office of the High Level Investigation Committee of the Korea Infrastructure Safety Corporation under consignment from the Ministry of Land, Infrastructure and Transport. The construction site accident population used in this study is difficult to represent the entire construction site accident, but is considered to have statistical value as analysis data for a given size of construction site accident. The analysis is believed to be available on site as a basic data for securing construction safety and is expected to be used as a data for establishing future direction of construction safety policy.
