The vessels under explosive impact loading have good blast-resistant characteristics.

Then, the blast resistance of a shallow-buried blastproof structure made of it is also studied under explosion load, according to the material property experiment results above.

Based on test method of national standard of anti-deflagration,influences of moisture and charge density on anti-deflagration of permissible expanded ammonium nitrate explosive have been tested and investigated,residual mass of acceptor explosive have also been measured at same time.

The experiment applies hybrid fiber with low(polypropylene fiber) and high melting point(steel fiber) to improve mechanics properties and spalling resistance of high performance concrete,since high performance concrete easily spallings and destroys when on fire.

In order to realize experimental investigation of explosive phenomena, blast-resistant performance of structure or material at stable environment,the large-scale equipment used for indoor blast test was designed with vibration reducing method.

The way to improve the blast-resistant performance of the important buildings has become an important consideration for structure engineers in the phase of designing.
