Abstract

The invention discloses a civil engineering structure explosion damage experiment platform. The civil engineering structure explosion damage experiment platform comprises a base plate, a plurality ofsupporting columns and a plurality of transverse rods welded to the corresponding supporting columns, wherein a locking device for fixing a test piece is arranged in the middle of the base plate; a first testing device and a second testing device which are used for testing explosion parameters are symmetrically arranged on the two sides of the locking device; a fixing device used for fixing explosives is arranged on the plurality of transverse rods, the first testing device comprises two protection plates arranged at the two ends of the base plate respectively, and a plurality of screw rods are arranged on each protection plate in a penetrating and sliding mode. The civil engineering structure explosion damage experiment platform is novel in structure, can test detonation pressure parameters in all directions around the test piece, can resist the impact force by means of the strength of the first test plate and the second test plate when shock waves generated by explosion are spread all around, and can further convert kinetic energy of the shock waves into kinetic energy and internal energy of multiple devices, thereby preventing the experiment platform from being damaged.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to an experimental platform for explosion damage of civil engineering structures. Background technique [0002] Explosion mechanics is an interdisciplinary subject between fluid mechanics, solid mechanics, physics, and chemistry. It is widely used in weapon development, transportation, water conservancy construction, and civil engineering. Due to the particularity of civil engineering itself, compared with ordinary chemical drug explosion tests, only the unconstrained explosion is considered in civil engineering explosion experiments. Therefore, the experimental platform used for explosion damage of civil engineering structures also needs to have structural characteristics such as high strength and impact resistance. [0003] Existing explosion damage test platforms for civil engineering structures are relatively simple, such as the explosion damage test platform for civi...
