摘　　要：爆炸条件下，作用于防震塌内衬结构上的爆炸震塌荷载大小及分布规律问题尚未研究清楚。本文通过野外化爆试验方法，对接触爆炸条件下防护结构背爆面的震塌荷载及其分布规律进行了研究，得到作用在防震塌内衬结构上的震塌荷载种类及分布规律，为防护结构抗爆炸震塌内衬结构加固设计计算方法提供了试验依据。In the explosive conditions, the scale and distribution of the blast spalling load ture has not yet been studied well. In this paper, the scale and the distribution of spalling on the innerlining struc- load on the back surface of the protective structure in conditions of contact explosion have been studied by field explosion tests, and types and distribution law of the spalling load on the inner steel plate of the protective structure have been obtained. The results can provide experimental basis for design- and calculation methods of anti explosion inner reinforcement of protective structures.
