*城市地下大空间防灾中的几个重点问题
Key Index of the Disaster Prevention of Large Underground Space
摘要
Abstract
With the exhaustion and saturation of the shallow underground space,the development of urban ar-ea is more and more relying on the excavation of deep underground space.Nowadays,the advanced technology of high strength concrete,excavation method in soft soil and ground deformation control make it possible to build un-derground space with a larger scale,span length and depth.The common disasters and hazards that large urban un-derground space faces are the same as that of ordinary underground space,but considering the damage and the res-cue difficulties,more attention should be paid to the influence of disasters on large underground space.The study and research on the evaluation of the disaster prevention system of underground space still have not raised enough attention yet.The comprehensive assessment of the disaster prevention system is set up based on the study of the characteristics of large underground space itself and disaster effects.Several key indexes selected from the preven-tion rules of fire,flood,and earthquake are discussed.关键词
