中文摘要
本研究的目的是:(1)为地下生命线结构的抗震修复提供有效的指导;(2)为现有埋地生命线结构在各种地震环境下的易损性评估提供技术信息;(3)制定和记录修复和加强这些脆弱结构的成本效益方法。包括水、下水道、天然气和石油管道在内的地下生命线在地震中受到严重破坏,其中包括1985年墨西哥城地震、1987年加利福尼亚州惠蒂尔地震和最近的1989年10月17日洛马普列塔地震。现有的地下生命线即使在中度地震下也不安全。由于生命线对公众的健康、供应和安全的重要性,生命线地震工程需要更多的关注。由于目前还没有成文的地震规定来设计埋地生命线,大多数供水和污水管道,包括相对较新的管道,都是在最低限度的地震保护下建造的。地震对供水和下水管道的破坏是不可避免的,经济损失可能是巨大的。本项目将探讨在紧急情况下和永久基础上的有效修复方法。由于更换所有现有的供水和污水管道是非常昂贵的,如果不是不可能的话,因此迫切需要制定有效的修复技术和战略,以便由拟议的研究制定。
英文摘要
The objectives of this proposed research are to: (1) provide the effective guidance for repairs and rehabilitation of buried lifeline structures for seismic resistance; (2) provide technical information for realistic evaluation of the vulnerability of existing buried lifeline structures under various seismic environments; and (3) develop and document cost-effective methodologies for repairing and strengthening such vulnerable structures. Buried lifelines which include water, sewer, gas and oil pipelines have been damaged heavily by earthquakes including the 1985 Mexico City Earthquake, the 1987 Whittier, California Earthquake and the most recent Loma Prieta Earthquake of October 17, 1989. Existing buried lifelines are unsafe even under moderate earthquakes. Because of the importance of lifelines to the health, supply, and safety of the public, lifeline earthquake engineering needs greater attention. Since there is still no codified seismic provision to design buried lifelines, most water and sewer pipelines, including relatively new ones, have been built with minimum earthquake protection. Damages to water and sewer pipelines during earthquakes are unavoidable and economical loss can be substantial. Effective repair methods under emergency situations and for a permanent basis are to be addressed by this project. Due to the fact that the replacement of all existing water and sewer pipelines is very expensive, if not impossible, the development of effective rehabilitation techniques and strategies to be developed by the proposed research is urgently needed.
