项目摘要

This study deals with development of a support system for reinforcement and restoration of sewerage facilities against earthquake disasters in considerig environmental assessment. A summary of results obtained from this study are as follows.1. The small scale tests were carried out in order to clarify the effectiveness against the liquefied ground flow by using the gravel drain systems. Test results suggested that ground flow was reduced by installing the gravel in sandy ground under the influence of rigidity of gravel drain.2. The restoration operation of water supply and sewerage systems in consideration of the protection of the environment were carried out in Shibecha town near the Kushiro city ater the 1993 Kushiro-oki earthquake. The details of its operation were investigated and the lessons which will be useful against the future earthquake disaster were obtainedQuestionnaire surveys on inhabitaints of Tannan area and local governments in Fukui prefecture was conducted to investigate the state of their awareness against water problems during earthquakes. Although inhabitants feel that stock of water is necessary for their life after earthquake, its quantity is insufficiency. Furthermore, though many local governments make an effort to take measures against earthquake disasters after 1995 Kobe earthquake, its effort is insufficiency as compared with the advanced local governments regarding earthquake disaster prevention.

这项研究涉及在考虑环境评估中对地震灾害的加强和恢复污水处理设施的发展。从这项研究中获得的结果摘要如下1。进行小型测试是为了通过使用砾石排水系统来阐明针对液化地面流的有效性。测试结果表明，在砾石排水刚度的影响下，将砾石安装在沙质地面中来降低地面流量。2。考虑到环境保护的供水和污水处理系统的恢复操作是在1993年的Kushiro-Oki地震中在Kushiro City Ater附近的Shibecha Town进行的。研究了其运作的细节，对未来地震灾难的经验教训是对坦南地区居民进行的Questionnaire调查，并进行了福生县的地方政府，以调查其在地震期间对水问题的认识。尽管居民认为地震后的水是其生命所必需的，但其数量是不足。此外，尽管许多地方政府在1995年的科比地震之后努力采取针对地震灾难的措施，但与高级地方政府在预防地震灾害方面相比，其努力是不足的。
