摘要
基于对中国唐山地震、美国北岭地震和日本兵库县南部地震城市生命线的震害研究 ,探讨了城市生命线震害相互影响的一些重要课题。这些相互影响的主要原因是各生命线之间存在相互制约性、近距离共存性和某些条件下的互用性、相互替代性。生命线之间相互影响的主要形式是构造影响、机能影响、恢复机能影响与产生次生灾害等。通过影响度分析 ,定量评价了相互影响程度。依据影响度时序 ,提出了各城市生命线震后恢复的时序 ,并以实例验证了研究结果 ,具有很高的吻合性。
Based on the studies of urban lifeline damages of Tangshan earthquake, China, Northridge earthquake, U.S.A, and Hyogo?ken Nanbu earthquake, Japan, several important problems of interaction of urban lifeline earthquake damages are investigated. The main reasons of such interaction are due to the mutual restraint character, coexistence in close quarter and the ability of mutual application and substitution under certain conditions existed among the lifelines. The main forms of interaction of lifelines are construction effect, function effect, restoring?function effect and evolution of secondary earthquake disasters. The degree of interaction is evaluated quantitatively by analyzing the degree of mutual effect. According to the order of degree of effect, schedule of restoration of lifelines in each city is put forward. It is proved that the research results highly coincide with the actual cases.
