After its construction, the structure of retaining wall, which is constructed for protecting horizontal earth
pressure, weakens in function, since , following elapsed time, it is affected and deteriorated by various causes such as external weight. climate change, material degradation and others. Especially as localized
torrential downpours have recently increased due to environmental climate change, conduction age of
existing retaining wall, which conducts with material deterioration, has also been increasing.
Therefore, in order to make use of facility during durability term which was set at the point of
planning and designing, we need to select appropriate construction methods. Furthermore, to ensure safety,
construct ability and durability during using time, we should also set up plans and measures for
maintaining.
Because it is required for building structure to enhance social environment necessities, landscape
gardening, and life-quality improvement, recent buildings have been designed not only for fulfilling its own
function, but also for intensifying comfort in beauty and landscape. This request has been kept on
increasing. Nowadays measures and solutions have been introduced to make housing complexes more
eco-environmental and take optimal advantage of their space. Furthermore, due to frequent localized
torrential downpours caused by environmental contamination, collapses of retaining wall structure have
increased, so that it is required to enhance structural strongness.
In order to fulfill a series of maintaining activities efficiently and lengthen the durability of retaining
wall structure, reasonable strategic objectives and detailed manuals for maintaining have to be prepared. In
addition, the interest of Soil-nailed Natural Surface(SNS) construction method, which has landscape
gardening function in accordance with these requirements, has been increasing.
This research focuses on the stability and effectiveness of the soil-nailed natural surface(SNS)”method,
which is eco-friendly and functions as retaining wall structure.
