Since the mid-1980s, approximately 4,160,000 apartments have been built in Korea, and more than 70% of these apartments were high rise apartments having 11 floors or more. Meanwhile, most of the apartments were built in the wall-slab structure, and this kind of wall-slab high rise apartment is a building structure native to Korea of which its demolition cases cannot be found in other countries. Consequently, it can be said that it is absolutely necessary to develop and establish a safe and effective demolition technology in order to prepare for the upcoming time for demolition of wall-slab high rise apartments.
So, in this paper, foundamental experiments were carried out using real wall-slabs of apartments. As one of experiments, high pressured brick walls were used for experiments, and relation between thickness of the wall and amount of adequate charge was obtained. Another wall was the shear wall of reinforced concrete, good relation between the shear wall and amount of adequate charge was obtained.
韓国の高層アパート群はそのほとんどが，壁式構造物である。壁式構造物の発破解体例は，世界にもほとんど例がない。そこで，実際の壁式構造物の壁を用いて，発破実験を行った。まず一つは高圧煉瓦でできた壁を対象に発破を行い，壁の厚さと装薬量の適正な関係を求めた。ついで，鉄筋コンクリートで出来たせん断壁の発破実験を行い，この壁の場合の適正そう薬量を求めた。これらのデータは将来の高層アパートの発破解体に大いに役立つものである。
