開発途上国では，伝統的な石積みやレンガ積みといった脆弱な建物が多いため，地震の崩壊による人的被害が多発する傾向にある．2015年のネパール地震における人的被害の大半は，山間部の自分で建設した石積の伝統的な家に集中しており，建設資材の搬入が困難である山間部では，地震から約3年半が経過した今でも壊れた壁の状態で，危険な住居で生活されている方も多くいるのが現状である．このような状況を減らすため，まず，現地の住民の方々が自ら理解・自立し，加えて安価に実施し得る耐震補強方法を確立し，現地に伝えていく必要がある．そのための補強方法として，ジャケッテイング工法を提案し，実大実験を実施することにより効果の検証を行った．この一連の試みを広く知ってもらうため，広報を兼ね，クラウドファンデイングを活用した研究推進を行い，その活動を中心に報告する．In developing countries, there are many vulnerable buildings made of traditional masonry and brickwork and the human damage caused by the collapse of the earthquake tends to occur frequently. Most of the human casualties in the 2015 Nepal earthquake are concentrated in traditional stone masonry houses in the mountain areas. In the mountain areas where it is difficult to carry construction materials, many people still live in dangerous houses with broken walls even after about three and a half years since the earthquake. In order to reduce such situations, it is necessary to establish an earthquake retrofitting method and inform the local people so that local residents can understand by themselves and implement at a low cost. Therefore, the jacketing method with gabion mesh as a reinforcement method was proposed, and verified its effect by conducting full-scale experiments in this study. In order to publicize this series of trials, research promotion utilizing crowdfunding was carried out.
