Hong Won-pyo: Underground Excavation Cases

In our country, recent high-income industrial development, low paper space production and increased land use are increasing. This trend is in the future, with an increase in underground drilling to build large-scale underground structures for efficient use of urban paper. When drilling in the city center is done close to surrounding structures and lithography, the soil membrane becomes more or less a wall deformation and the strength of the ground is lowered, causing problems with the stability of the drill ground. And it has a significant effect on the surrounding sub-station, so that when the earth is in the air, the cracks and collapses of the adjacent structures are often caused by the deformation of the wall. The accidents are not only devastating to property but also, in severe cases, serious fatal accidents. Thus, when the digging is done, the ground - soiling of the ground is built on the ground to prevent the flow of local ground and groundwater and to protect the adjacent structure. The traditional dirt wall was mainly used for soft walls with large piles and paneling, and the earthen wall support system is being used for support with support of the support of support and support of a support system. But these dirt-dark structures can cause major deformation and poor restructuring and many human lives and economic losses during the drilling process. To prevent this from happening, recently the hot soil walls and underground walls have been used by relatively powerful walls. The use of these methods has caused some improvement in the geometry and arithmetic but is not yet recognized by safe methods.
