项目摘要

The main results of this study may be summarized as follows :1. A means of establishing preventive measures was presented for mitigating earthquake damage by making the most of a variety of information and such advanced technoligies as computer technologies on-line in real time, using studies and systems now in operation. This study focused on the concept and importance of real-time earthquake engineering. Active control of social systems taking into account human behavior also was dealt with.2. A seismic information gathering and network alert (SIGNAL) system for a large-scale city gas network was developed based on extensive earthquake monitoring and geophraphic information system (GIS). The damage estimation to custimers' buildings and pipelines, estimation of the magnitude and hypocenter, evaluation of the response spectrum, and decision analysis whether to shut-off or maintain the supply based on the estimated results were conducted.3. A new simulator for human evacuation behavior using virtual reality (VR) was developed and applied to study evacuation from a maze. It was found that evacuation behavior can be simulated by the VR system, and the trainig using VR helps smooth evacuation from the maze. Considering the issues related to disaster drill, such as its mannerism, decrease of participants and their low volition, and safety of the drill, this VR simulator has high potential and can be a useful tool for disaster mitigation.4. Importance or criticality in relation to a road network was evaluated in terms of the importance of the route the bridge located in the road network as well as the direct effects when the bridge is destroyed. Priority for retrofitting bridges and for emergency response after an earthquake occurrence can be decided accoring to the importance factor of the bridge as a vital transportation link.

本研究的主要成果如下：1.提出了一种充分利用各种信息和计算机技术等先进技术，利用已有的研究成果和系统，实时在线建立防震减灾措施的方法。本研究重点阐述了实时地震工程的概念和重要性。2.还讨论了考虑到人类行为的社会系统的主动控制。基于广泛的地震监测和地理信息系统(GIS)，开发了大型城市燃气管网地震信息采集与网络预警(信号)系统。对震源建筑物和管道进行了破坏估计，震级和震源估计，反应谱估计，以及根据估计结果进行断电或维持供电的决策分析。开发了一种基于虚拟现实技术的人员疏散行为模拟器，并将其应用于迷宫疏散研究。研究发现，虚拟现实系统可以模拟人员的疏散行为，利用虚拟现实技术进行训练有助于人员顺利撤离迷宫。考虑到灾难演练的举止、参与者的减少和意志的低落以及演练的安全性等问题，该VR模拟器具有很高的潜力，可以作为一种有用的减灾工具。根据桥梁位于公路网中的路线的重要性以及桥梁被摧毁时的直接影响，对公路网的重要性或关键程度进行了评估。根据桥梁作为重要交通运输环节的重要性因素，可以确定桥梁改造和地震发生后应急反应的优先次序。
