摘要

In order to study the law of shock wave propagation due to explosion inside half-airtight space. Measure the propagation characteristic of shock wave due to TNT explosion inside half-airtight tunnel. Get the overpressure curve of different mass of TNT in certain distance, comparison with the curve among the air blast and that of explosion inside the closed space. Analyze the law of shock wave propagation due to explosion inside half-airtight space, the results indicate that the overpressure curve has two peak values due to explosion inside the half-airtight space, and only one peak value in the free space, but inside the closed space, that has two or more peak values, which is resulted by the structure of halfairtight tunnel, and at the same time demonstrate that the structure of explosion is the key factor on the law of shock wave propagation. Which also help to do some theory research on the law of shock wave propagation.
