BASIC STUDY ON THE DAMAGE REDUCTION TO HUMAN AND PROPERTIES ON AND NEAR THE ACTIVE FAULT IN THE CASE OF MUNICIPALITY

（1）以山口县山口市为研究对象，确定了山口盆地活动断裂的位置、长度、方向。（2）在上述活断层研究成果的基础上，通过钻孔试验确定了地表结构。(3)We对确定地下结构的地面进行了动力响应分析。我们研究了地面的动力特性。(4)We估计了山口盆地的地震强度(5)By采用离散单元法研究了房屋的动力特性和倒塌过程，并进行了振动台试验。根据上述模拟和测试结果，我们对住宅的危险性进行了评估。(6)At与此同时，我们还对2004年新潟县地震造成的人员和财产损失进行了调查。(7)We利用Distinct EL软件开发了应急疏散模拟程序 ...更多信息 方法。利用该程序研究了人群疏散过程的特点，提取了疏散过程中的瓶颈。(8)In摘要为了建立灾区与政府的信息沟通系统，我们提出了一种新型的沟通系统。该系统的基本思想是在灾害发生后立即在受灾地区建立移动台站。然后使用中继系统来传递重要信息。研究了天线高度与信号可达距离的关系，并对实际安装进行了研究。（9）开发了从市町村到都道府县的信息收集、处理和传输系统，即使在灾害发生时也易于使用。（10）根据上述个别研究结果，对如何减少地震灾害进行了调查，并研究了市、县政府的方法和策略。少

(1)Taking Yamaguchi city, in Yamaguchi Prefecture as an investigation field, we determined the location, length, direction of active faults in Yamaguchi basin.(2)Then, based on the above research results about the active fault, we determined the structure of surface ground with the aid of boring tests.(3)We performed the dynamic response analysis for the ground which we determined the underground structure. And we studied the dynamic characteristics of the ground.(4)We estimated the seismic intensity for the Yamaguchi basin.(5)By using the Distinct Element Method, we studied the dynamic behavior and the collapse procedure of a house, and performed shaking table test. We assessed the danger of a dwelling house based on the above simulation and test results.(6)At the same time, we performed investigation of the damage to human and properties caused by the Niigataken Chuettsu earthquake in 2004.(7)We developed the simulation program of evacuation in the case of emergency using Distinct El … More ement Method. By using the program, we studied the characteristics of the evacuation procedure of crowd and extracted the bottle neck in the evacuation.(8)In order to set up the information communication system from the damaged area to the authority, we proposed a new type of communication system. The basic idea of the system is we set up the portable stations at the damaged areas just after the occurrence of the disaster. Then using the relay system important information is transferred. We investigated the relation ship between the height of antenna and the reachable distance of signal, and so force and studied the actual installation.(9)Also, we developed the information gathering, processing and transmitting system from municipality to prefecture government, with is easy to use even in the time of disaster.(10)Based on the above individual research results, we investigated how to reduce the victims by the earthquake, and studied the methodology and strategy of the municipal and prefecture government.
