This topic is on the extension of the continuing research of collecting the digital record of strong earthquake acceleration, and its aim is to establish the measurement system of earthquake acceleration records in the intake tower of the reservoir. In 1995, the investigator had worked to get the acceleration record by placing the accelerometer in the top of the RC-intake tower built in the reservoir of NAGARA dam, which was constructed by BOSO canal project of Water Resources Development Public Corporation. The dam was located on the border between Ichihara city and Nagara town in Chiba prefecture. The fundamental concern of the research is to investigate the nature of the vibration characteristics of an intake-tower caused by earthquake.The Main installations and the benefits obtained by the project are as follows.1. Installation of the accurate real time measure and time marking system using the GPS system to the placed accelerometer.2. Installation of the wireless digital communication system from the accelerometer to any distanced place using the NTT mobile telephone system. This was done by attaching the mobile telephone to the placed accelerometer, and the accelerometer always stand by to accept the command by the remote recording place anywhere connected by telephone network.3. Amending or renewal of the laboratory accelerometer at the Tokyo University of Agriculture & Technology, of which recording mechanism had been failed into unrecoverable state. This instrument was another accelerometer aiming to measure the common building earthquake motion, and had an old fashioned recording system. The new replaced accelerometer of the same type equipment as the intake tower was installed at the laboratory of Kyoto University.

本课题是强震加速度数字记录采集继续研究的延伸，旨在建立水库进水塔地震加速度记录测量系统。1995年，调查人员在水资源开发公共公司的BOSO运河项目建造的NAGARA大坝水库中建造的RC进水塔顶部放置加速度计，以获得加速度记录。该大坝位于千叶县市原市和长良镇之间的边界。本研究的主要目的是探讨地震作用下进水塔的振动特性，主要研究内容和取得的效益如下：1.利用GPS系统对放置的加速度计进行精确的真实的时间测量和时间标记系统的安装.使用NTT移动的电话系统安装从加速度计到任何远距离地点的无线数字通信系统。这是通过将移动的电话连接到放置的加速度计来完成的，并且加速度计始终待命以接受通过电话网络连接的任何地方的远程记录地点的命令。东京农业技术大学实验室加速度计的修正或更新，其记录机制已陷入无法恢复的状态。该仪器是另一种加速度计，旨在测量常见的建筑物地震运动，并有一个老式的记录系统。在京都大学实验室安装了与进水塔相同类型设备的新更换的加速度计。
