摘要
随着经济和城镇化的发展,我国出现了大量的城市密集建筑群,包含了大量的密级高层建筑、人口和财物,是城市防震减灾工作的重要对象和新挑战.随着地震工程研究和应用的迅速发展,建筑倒塌等传统震害逐渐减少,而坠物、地震次生火灾等新型地震灾害愈发突出.这些新型灾害破坏性大,缺少有效的减灾对策.基于此,面向地震次生坠物、地震次生火灾、震后电梯人员受困、地震场地-城市效应问题等四类典型新型地震次生灾害,总结了当前关于新型地震次生灾害的初步研究成果并展望未来研究方向,以期为地震新型灾害研究提供参考.
Abstract
High-density building clusters,with a large population,a number of high-rise buildings,and significant assets,have been noticeable in the context of economic and urbanization progress.These provide focal points as well as new challenges for urban seismic mitigation and disaster prevention.Concurrently,with the progress in seismic engineering research and its practical applications,traditional seismic risks,such as structural collapses,have seen a gradual decline.Nonetheless,novel seismic disasters,such as post-earthquake falling debris and fires,have gained prominence.These are extremely destructive and lack effective mitigation measures.Therefore,the paper focused on four typical novel seismic secondary disas-ters:post-earthquake falling debris,post-earthquake fires,people trapped in elevators under earthquakes,and site-city interaction effects.The current preliminary research findings on novel seismic secondary disas-ters were summarized,and an outlook on future research directions was proposed,so as to provide a scholarly reference for the exploration of novel seismic disasters.
