Water Supply System rooted in Natural Climate for Earthquake Fire in Wooden Cultural City

1995年的坂神淡路地震不仅摧毁了抗震结构，同时也引发了大量火灾，特别是烧毁了木制住宅区。发生特大火灾的原因是地震火灾可用水准备不足。本文以日本京都木文化城为研究对象，通过对城市居民对区域天然水认识问卷调查，为保持居民对天然水作为防灾供水系统的认识提供了有效的规划方法，并对城市天然水的维护进行了实例分析在京都市6个水资源条件相同地区，作为防灾系统进行供水。这些方案的设计是为了保证三个阶段的消防安全系统和人们日常生活中与区域水的关系，建立了包含各种防灾供水系统实例的数据库，以展示这些实例研究的成果。这些有效的天然供水利用系统也暗示了地震安全城市的条件。

Not only did the 1995 Hanshin-Awaji earthquake demolish the quake-resistant structure, but also caused an amount of fire at the same time, especially burning the wooden-made housing areas. The reason that big fire occurred is that available water for earthquake fire was not prepared sufficiently. This paper focused on the natural water supply as the fail-safe system in the wooden cultural city as Kyoto city in Japan, in case that ordinary system including hydrants was out of service.The questionnaire for citizen's consciousness to the regional natural water showed the direction of effective planning method for keeping their recognition of natural water as a disaster prevention water supply system.The case studies to maintain a natural water supply as a disaster prevention system was planned for 6 regions which have each other water condition in Kyoto city. Those plans were designed to keep the fail-safe system for 3 phases of fire fighting and relationship between people and regional water in usual daily life.The data base which includes many kinds of example of disaster prevention water supply system was built for showing the achievements of those case studies.Each region has water supplying potential in their natural climate. Those effective use system of natural water supply also hints the condition of Earthquake Safe City.
