摘要
城市的维生管线工程作为保证城市正常运行的基本设施,是影响到城市居民日常生活的重要组成部分。在2011年发生的3·11东日本大地震中,位于震中附近的日本仙台市的维生管线受到损坏。立足于日本仙台市在3·11大地震之后维生管线的恢复,通过分析仙台市在3·11地震之后供水系统所发生的故障、损害与其处理对策,总结了易受灾难损坏的供水管路的地基形态与管道种类。通过分析,能够确定供水管路的防灾优先度与优先范围,在灾害来临之际防患于未然。
The lifelines are closely related to the daily life of the urban residents. In Sendai City, Japan, the lifelines were severely damaged in the Great East Japan Earthquake. In this paper, the recovery of the lifelines in Sendai City after the Great Earthquake is discussed. Through the analysis of the damages and countermeasures in water supply system, the dangerous ground and dangerous pipe types are concluded. These concluded results would help to determine the protection priority and protection range of the dangerous water pipes against disasters, and help to prevent the heavy damages in advance at the upcoming disasters.
