Damage Effect of Shallow Buried Civil Air Defense Engineering Structures under Nearby Blast Loading

doi:10.3969/j.issn.1000-1093.2021.03.019

Abstract

Abstract: The semi-buried and fully-buried civil defense engineering structures under the conditions of different blast distances and charge masses were experimentally studied to investigate the damage effects of civil defense engineering structure under blast loading. The dynamic response and damage characteristics of civil defense engineering structures are analyzed through 11 batches of blast experiments with a large scale ratio of 1/3.The results show that the overpressure generated by blast shock wave on the external wall is related to the stiffness of wall panel，and the design load of external wall structure should be the load at the maximum stress position of wall surface.The damage effects caused by the contact blast near the outer wall of semi-buried basement and the ground-shock explosion near the fully-buried basement are related to the overpressure on the wall surface，and also closely related to the duration of explosion，surrounding media，and structures in the medium.

Key words: civilairdefenseengineering, explosion, shallow-buriedstructure, experimentalresearch, damageeffect
