项目摘要

An operating system for questionnaire survey of seismic intensity was developed on a computer in order to realize more quick and systematic survey soon after the occurrence of damaging earthquakes.Seismic intensity is a convenient but comprehensive measure to evaluate severity of ground motions without any instruments and have been widely used in all the earthquake prone countries from the beginning of modern seismology. In Japan, seismic intensities are officially estimated by the Japan Meteorological Agency immediately after the occurrence of earthquakes but these data are too fragmental in space to discuss detailed distribution of seismic severity. In 1972 a new statistical method for seismic intensity survey was developed by use of a number of questionnaires. Since then, this method have been adopted to the most of damaging earthquakes occurred in Japan and some of that in overseas by many researchers including the investigators of this project. However, there have been no standard … More ized operation scheme for surveying until now and each survey have been carried out with temporary way. Consequently, it have been difficult to do the survey without an expert's participation and sometimes it take much time to get final results. In order to systematize, this project is started to develop an operating system for seismic intensity survey.The operating system contains all the procedures from a stage of decision making for survey to the final stage of presentation of estimated results. At the beginning of the project, plenty of experiences of all the investigators were gathered through brainstorming and whole the survey procedures were reconstructed into a logical rule bases. The procedures are divided into four modules of grasping isoseismals from the initial fragmental intensity data, decision making of survey, strategy for delivering and collecting questionnaires, and data analyses and presentation. For each module, the rule bases are transferred into computer programs. In parallel, a construction of related database is also done. Less

为了在破坏性地震发生后更快、更系统地进行调查，在计算机上开发了一个地震烈度问卷调查操作系统。地震烈度是一种不需要任何仪器就可以方便而全面地评估地面运动强度的指标，从现代地震学开始就在所有地震多发国家得到了广泛的应用。在日本，日本气象厅在地震发生后立即正式估计地震强度，但这些数据在空间上太零散，无法讨论地震严重程度的详细分布。1972年，通过大量问卷调查，发展了一种新的地震烈度调查统计方法。此后，包括该项目的研究人员在内的许多研究人员对日本发生的大部分破坏性地震和国外的一些破坏性地震都采用了这种方法。然而，还没有标准的…到目前为止，测量作业方案较多，每次测量都是以临时方式进行的。因此，在没有专家参与的情况下很难进行调查，有时还需要很长时间才能得出最终结果。为了系统化，本项目启动了地震烈度调查业务系统的开发，该业务系统包含了从调查决策阶段到评估结果最后呈现阶段的所有程序。在项目之初，通过集思广益，收集了所有调查人员的大量经验，将整个调查程序重构为一个逻辑规则库。程序分为从初始碎片化烈度数据掌握等震线、调查决策、发放和收集问卷策略、数据分析和呈现四个模块。对于每个模块，规则库被转移到计算机程序中。同时，还进行了相关数据库的建设。较少
