 note = {兵庫県南部地震(1995) で被災した宝塚市で世帯別アンケートを行い、住宅被害・ライフライン停止・生活支障・待避避難の発生状況について調査した。調査結果をもとに、生活支障の強さを計量評価するとともに避難世帯の発生率を算定し、両者の関係を示す実験式を導いた。この実験式にライフラインの停止状況を説明変数として生活支障の強さを評価する方法を連結し、ライフラインの停止状況が避難世帯の発生率に及ぼす影響を試算した。試算の結果、1)ライフラインの停止期間が短縮することに伴う生活支障と避難率の低下傾向は棺数のライフライン(水道とガスの組み合わせなど)の停止期間が短縮したときに顕著に現れることが明らかになり、2) 兵庫県南部地震での宝塚市での電気、水道、ガスの停止日数がそれぞれ実際の4分のlに止まっていたならば、住宅の被害が軽微だった世帯の避難は発生せず、避難世帯の数は実際の半分程度に止まっていたことが推定された。, A questionnaire survey on housing damage, lifeline suspension, daily living disruption, and sheltering was done in Takarazuka, an affected community in the 1995 Hyogo-Ken-Nanbu earthquake. Based on the survey data, first, a relationship between numerical scores for the extent of daily living disruption and evacuation rates was derived. Second, connecting the relationship with a method for evaluating daily living disruption scores based on the periods of lifeline suspension, we conducted a sensitivity analysis between lifeline suspension and evacuation. From the analysis, it was shown that evacuation rates are remarkably reduced when two or more lifelines, such as the combination of water and gas systems, have shorter recovery periods. Also, from a case study for Takarazuka with hypothetical suspension periods given at 1/4 as short as the actual suspension periods in the 1995 earthquake, it was estimated that no families having only minor housing damage would have evacuated themselves, and, accordingly, the number of evacuated families would have been reduced to half., postprint},
