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.

本研究系针对地震环境影响评估中污水处理设施之补强与重建，发展一套支援系统。从本研究中获得的结果总结如下。为了阐明碎石排水系统对液化土流的有效性，进行了小型试验。试验结果表明，在桑迪地基中设置碎石，在碎石排水板刚度的影响下，减小了地面流量. 1993年钏路大地震后，在钏路市附近的芝茶町进行了考虑到环境保护的供水和排水系统的恢复作业。通过对潭南地区居民和福井县地方政府的问卷调查，了解了地震期间人们对水资源问题的认识状况。虽然震后居民认为水的储备是生活所必需的，但其数量是不足的。此外，1995年科比大地震后，虽然许多地方政府都采取了措施来应对地震灾害，但与先进的地方政府相比，其努力是不够的。
