    We discuss about the resilience and robustness of infrastructures against both inter-plate and intra-plate earthquakes to enhance the hard and soft measures. For the typical inter-plate earthquakes such as 2011 Off the Pacific Coast of Tohoku earthquake and coming Nankai Trough earthquake we developed pseudo point source model and carried out the simulation of strong ground motion. For the active fault-induced earthquake like the 2016 Kumamoto earthquake, we estimated the resilience and robustness of infrastructure against a large displacement due to fault movement. Moreover seismic behavior and performance under the multi-hazard of strong ground motion, geohazard and tsunami were investigated.

    Characteristics of Nankai Trough Earthquake are a long predominant period, a long duration, attack of tsunami after the strong shaking and a extensive damage area. In this study, we make clear an aseismic safety level of infrastructure, structural and functional capacity of infrastructures for the social requirement and the countermeasures for preventing earthquake damage. We assessed an adequate input ground motion for the design of structures, and evaluated the earthquake and tsunami prevention strategies and countermeasures especially for lifeline systems such as railway, roadway, water, gas, electricity and various pipelines. In order to realize these issues and extend the applicability, we conducted numerical simulations by using such advanced simulation methods as FEM, DEM and SPH. Centrifuge experiments were also conducted to verify such computer simulation. The results obtained would be useful resources for soft and hard measures of mitigating earthquake and tsunami disasters.

    Earthquake damage to underground structures of which extent can not be ignored are too numerous to enumerate in the recent large earthquakes after the 1923 Kanto Earthquake. However, the issue to be improved is the absence of perspective that the underground structures with spatially extent should be considered as a line, a plane or a volume structures with 3-dimensional behavior. In this study, we intend to deal with the underground structures comprehensively from their input ground motions to seismic behavior. We conducted the analyses and discussions by considering the suitable aseismic design and countermeasures.

    1. Site investigation and information gathering on casualty and emergency action were done after the 2004 Niigata Chuetsu earthquake. Relation between casualty and seismic intensity, and other issues were analyzed based on the obtained data. 2. Optimized problems were analyzed on the emergency transportation systems for injured persons after earthquakes to save human lives. 3. States of the arts of communication systems for disaster information after earthquakes were investigated. It revealed that seismic countermeasures of optical cables and early warning systems must be researched further more. 4. Evaluation method of seismic risk of road systems was obtained based on the data during the 2004 Niigata Chuetsu earthquake. 5.

    We learned from 1995 Kobe Earthquake, that wooden houses which are clustered close together, suffered damages and made terrible death of residents. One reason is the delay of detecting damages, which occurred at the same time and at many places. In this study, we propose a new method for detecting houses collapse, which is using telephone line. Nowadays, Most houses are linked to the telephone building with copper wire, and the state of this telephone line is investigated by the telephone company. At the disastrous time, the area which is suffered heavy damages, could be detected from the damage of telephone lines. We have investigated the strength of drop-wire (connection between telephone pole and house). It is clear that the inclination with 1/10 of a house makes the drop-wire cut The damage of telephone lines mean the damage of houses, then the information of telephone line is useful in early detecting house damages. Another subject is information system at the disastrous time, which distributes much information on disaster. In Japan, three measures are often used at the emergency time, those are priority telephone at the disastrous time, public radio system for anti-disaster and private communication network. Anti-disaster section need much information on damages which is gathered from many distribution channels. We think that above three measures should not be sufficient at the disastrous time. A new idea, named "Information Highway at the Disastrous Time" is proposed in this study. Combining with many anti-disaster sections, more reliable information system is needed to reduce the damage of society

    平成9年度には通信システムがどれくらい被害になっているのかを定量化する研究を重点的に行った。NTTアクセス網研究所から兵庫県南部地震における地下設備の被害状況のデータを提供してもらい、地震動と地下管路の被害率の関係の分析を行った。兵庫県南部地震では神戸市内を中心に多くの強震記録が得られているが、神戸市内の観測点周囲の被害率と地震動を対応させる研究を行った。既に発表されているガス管、水道管の被害数値と対比分析したところ、管種別ごとに明確な比例関係が見出せた。その結果をもとに地震動からNTT管被害を予測する推定式を導いた。この式を将来起こるであろう地震時に用いればNTT地下設備の被害状況が即時に推定でき、通信サービスへの影響も知ることができる。電柱や通信ケーブルについても同様の研究を進める予定である。 また電話のふくそうのメカニズムについて研究事例調査を行うとともに、災害時の情報伝達システムについても調査を行った。電話のふくそうに対して平成10年3月より「災害時伝言ダイアル」サービスが始められ、災害時の輻輳緩和に役立つとされている。しかし安否確認の問題だけでなく、防災関係機関で災害時に増大する通信量を把握する必要が有り、特にコンピュータを利用した防災システムの場合は従前に比べて通信量が急増する可能性もある。次年度以降に災害時の通信需要の増大と輻輳の関係について研究を進め、これらの定量予測を行っていきたい。それとともに防災関連機関共同で利用する「災害情報ハイウェイ」の研究を行い、災害時に使えるシステムを提案していきたい。

    ライフラインの信頼設計に関する研究を2つの柱に分けて行った。1つは過去の被害データの収集と分析であり、あと一つは地盤震動に関する研究である。過去の被害データの収集と分析では、被害が公表されているガス、水道について都市化が十分進展したと考えられる宮城県沖地震(1978年)以降の被害データを収集した。特に90年代に入ってから釧路沖地震、北海道南西沖地震、北海道東方沖地震、三陸はるか沖地震については関連自治体にアンケート調査を行い、被害データを収集した。95年1月の兵庫県南部地震については被害の全容はまだ公表されていないが、今後追加検討していく予定である。 被害データと地震動データを対比して判明したことは、加速度で200ガル、速度で30カイン程度のしきい値を超えると埋設管被害が発生しはじめ、それ以下では被害はほとんど起こっていない点である。阪神大震災以降いろいろな機関から強震観測計画が発表されているが、被害発生の目安は重要なポイントである。また過去の被害データから平均的な被害数の割り出しも可能であり、兵庫県南部地震のデータ公表をまって予測モデルを確立していく予定である。 また埋設管の耐震設計には応答変位法が一般的に用いられており、効果を発揮しているが多くの仮定を含んでおり、とりわけ入力地盤変位の問題は大きいと考えられる。そこで地震被害の集中しやすいといわれる地形の地盤震動シミュレーションを行い、地盤の運動速度や変位、地盤ひずみがどのように分布するかを検討した。その結果、地震被害が集中する傾向があるとされる軟弱層厚が変化する地形では、水平方向に平坦な場合に比べて速度、変位、ひずみとも大きくなることが確認された。この傾向の定式化は今後の検討課題であるが、ライフラインの信頼化にむけて取り組んでいきたいと考えている。

    The Kobe Earthquake occurred in Japan at 5 : 46 AM on January 17,1995 was an earthquake which directly attacked an overpopulated city from a hypocenter underneath the city. This type of earthquake first occurred in Fukui, Japan as the Fukui Earthquake in 1948 (M=7.1 ; 3,895 killed) and then it occurred again in Kobe City this time. In the Kobe Earthqukake, 6,308 lives were lost (including 5,501 lives lost immediately after earthquake and additional lives lost within 2 weeks due to injuries and others). Based on the number of dead persons, this was the greatest disaster since the Great Kanto Earthquake in 1923 (M=7.9 & 140,000 dead persons). We, Japanese earthquake engineers, thought that various kinds of structures such as wooden house, reinforced concrete buildings, steel and reinforced concrte highway bridges in Japan are strong enough against the strong eathquake because they are designed taking into account of the higher level of the earthquake force than any other coutries in the world, up to the Kobe earthquake 1995. In this earthquake, those structure were completely damaged more severely than we supposed. Therefore, the information about how severe the damage was could not be given to anywhere including Japanese government and municipal government, and as a result, so many persons could not survive. We learned the followings from the earthquake, 1) Electricity power supply become out of order by the strong earthquake. 2) The stop of electricity power causes the stop of water supply and resultantly the fire following the earthquake can't be extinguished. 3) Video camaras installed at the top of high buildings can get early the information about the damages on structures and the fires following the earthquake. 4) For the above purpose, the video cameras and their connecting communication facilities must be safe against the strong earthquake. It is an important problem left in the future.
