室内爆炸已成为当前建筑物面临爆炸灾害的主要形式之一。本文针对建筑物内化学炸药爆炸和可燃性气体混合物爆燃两种情况，从理论研究、模型试验和数值模拟3个方面总结并评述了当前国内外的研究现状，指出相关研究多以容器及管道内的爆炸试验或数值模拟为主，现有的理论模型对建筑物特点及使用功能考虑较少。

Internal explosion has become one of the main forms of explosion disasters faced by buildings. According to chemical explosive internal explosion and combustible gas mixture interior deflagration, the domestic and international researches are summarized and commented from theoretical analysis, experimental study and numerical simulation. It shows that most research results are obtained by explosion experiment or numerical simulation in containers and pipes, and the buildings' characteristics and functions are considered little in the corresponding theoretical model of internal explosion.
