Abstract

The invention relates to the technical field of engineering component testing, and particularly relates to a short-distance explosion test platform for a sunken beam plate component and a test methodof the short-distance explosion test platform. The short-distance explosion test platform comprises a sunken explosion pit, a protective cover plate, a beam plate component, a supporting device and adynamic data acquisition instrument, wherein the upper part of the sunken explosion pit is provided with a pithead; the protective cover plate covers the pithead and is provided with an impact actionhole, the protective cover plate is provided with a plurality of pressure sensors, and the plurality of pressure sensors are arranged at different positions of the protective cover plate in the horizontal direction; the beam plate component is arranged at the lower end of the impact action hole; the supporting device is arranged in the sunken explosion pit, and a plurality of displacement meters are mounted on the supporting device; and the dynamic data acquisition instrument is in signal connection with the pressure sensors and the displacement meters. According to the invention, damage to adetection instrument in the sunken explosion pit caused by reflection and diffraction of explosive shock waves can be avoided, related data is obtained for analysis and calculation, and a more accurate explosive load model is obtained to be used for anti-explosion design of an engineering structure.

Description

technical field [0001] The invention relates to the technical field of engineering component testing, in particular to a close-range explosion test platform for sunken beam-slab components and a test method thereof. Background technique [0002] Beam-slab structures are the most common basic components in civil engineering, and their safety against impact and explosion has attracted great attention from all over the world. Existing anti-blast test devices for beam and slab components are all exposed on the ground surface, and the reflection and diffraction of the blast shock wave will cause peeling or damage of the test instrument, resulting in failure to capture valid test data and resulting in huge test errors. [0003] On the other hand, practice has shown that even a small equivalent close-range explosion can cause serious damage to engineering components, and its failure mechanism involves the coupling effect of overall bending shear and local material failure. degree....
