Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can understand the present invention.

[0030] An anti-nuclear explosion simulation experiment system for underground civil air defense engineering. The experiment system includes a pre-excavated foundation pit 1 located below the ground surface 7, a prefabricated test component 4, a pressure monitoring system, a displacement monitoring system, and a nuclear explosion simulation loading device.

[0031] The foundation pit 1 is rectangular. The bottom plate 3, the side wall 21 and the side wall 20 are respectively poured with concrete at the bottom of the foundation pit 1, the side wall along the length direction and the side wall along the width direction. Both ends of the prefabricated test member 4 are placed on the upper part of the side wall 20 . Both sides of the prefabricated test member 4 are provided with...

Abstract

The invention relates to the technical field of civil engineering, in particular to a nuclear explosion resisting simulation experimental system and a nuclear explosion resisting simulation experimental method for underground civil air defense works. A prestressed concrete structural form and a parameter selecting range which are suitable for the civil air defense works are found out by researching the performance of a prestressed concrete structure under the action of a strong dynamic load, in particular to explosion resistance. The explosion resistance of the selected prestressed concrete structural form is checked by a large-scale model field chemical explosion experiment, thereby providing a design basis for application of the prestressed concrete structure in the civil air defense works.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to an underground civil air defense engineering anti-nuclear explosion simulation experiment system and an experiment method. Background technique [0002] How can we organically unify the larger span and higher resistance of civil air defense projects? Prestressed concrete technology provides a possibility for this. However, because the anti-blast structure is more complex and special than the general building structure, people have been afraid to use prestressed concrete structures for civil air defense projects for a long time. , there is an urgent need for an underground civil air defense engineering anti-nuclear explosion simulation experiment system and experimental method to verify the performance of prestressed concrete structures against strong dynamic loads such as explosions and impacts. Contents of the invention [0003] In order to solve the above-mentione...
