项目摘要

この研究は,伊勢湾沿岸の自然環境や外力条件の変遷を踏まえて,伊勢湾台風による高潮災害の歴史的位置付けを行らかにし,統計的手法や数値シミュレーション手法を用いて,高潮災害発生のメカニズムを解析するとともに,環境と調和した対策手法のあり方を検討した.得られた成果は次の通りである.1.名古屋港及び鳥羽港を対象として,験潮記録の確率統計処理を行った.棄却検定の結果,名古屋港では,最高潮位は伊勢湾台風時の資料は棄却できないことがわかったが,棄却しないと最も適合性のよい対数極値分布A型であっても,よく当てはめられないことがわかった.2.高潮による湾水の共振メカニズムには不明の点が多いが,任意形状の港湾に対して適応可能な解析方法を新しく見出すことに成功し,長方形湾に対して具体的に湾水応答を計算するとともに,透過潜堤を2列配置したときの波浪制御法を実験・理論の両面から提案した.3.伊勢湾における台風による高潮特性を明らかにするため,高潮の数値シミュレーションモデルを開発し,その精度を伊勢湾台風及び9019号台風による潮位の実測データとの比較によって検証した.また三重県長島町を対象とした氾濫シミュレーションから堤内地の建物,地勢条件の影響を検討した.4.伊勢湾を共有する愛知県と三重県における高潮災害を調べた結果,過去1200年の間に愛知県は4〜7回,三重県は5回,比較的大規模(死者100人以上)な災害が発生していることがわかった.5.対策工法の一つとして,捨石潜堤をとりあげ,異常時波浪に対する対波安定性を被覆部材の移動限界より検討した.そして,水理実験によって被覆部材の安定重量の算定式を被覆部材の設置位置の関数として提案した.

The location of the most exciting part of the history of environmental hazards along the coast of the Gulf of Illinois, the location of the most exciting part of the history of natural environmental conditions along the coast of the Gulf of Illinois, the location of the most exciting part of the history of natural environmental conditions along the coast of the Gulf of Illinois, the location of the most exciting part of the natural environmental conditions along the coast of the Gulf of Illinois, the location of the most exciting part of the natural environmental conditions along the coast of the Gulf of Illinois, the location of the most exciting part of the history of disasters in the coastal area of the Gulf, the location of the most exciting part of the history of disasters in the coastal areas of the Gulf of Illinois. You can get a lot of results. 1. Nagoya Port and Yoshimoya Harbor are very busy, and the statistics and confirmation rates of tide records are very high. However, the results show that in the Nagoya port, the peak water level in the Gulf of Iwo Bay, however, the weather data is not stable, but the data is the most reliable. The distribution of the number of climes is type A, and the temperature is very low. 2. The best part is that there are many unknown points in the bay water resonance, there are many points in the arbitrary shape of the harbor, the new analytical method is possible, the rectangular bay is successful, the specific calculation of the bay water is not clear, and the proposal is proposed through the two-column configuration of the submerged dike. The most exciting part of the characteristics of the Gulf of Illinois, the most exciting part of the TV station, the most exciting part, the best part, the most exciting part, the The town of the triple prefecture is like a building in the interior of the embankment, and the ground conditions are very difficult. 4. The results of the best part of the three-fold cycle in Yili Bay have been known. In the past 1200 years, there have been 4 times and 5 times in the past 1200 years. The large scale of the hospital (more than 100 dead) has caused serious damage to health workers. 5. As soon as the construction method is carried out, the stone submerged dike will be damaged, and the wave stability will be affected by the movement of the covered material at the limit. The weight of the covered material is calculated, the setting position of the covered material is calculated, and the number of the position is not recommended.
