Test device and test method for simulating anti-floating anchor-concrete slab composite structure

Abstract

The invention discloses an experimental device and an experimental method for simulating an anti-floating anchor-concrete plate composite structure. The experimental device comprises a load bearing device, wherein the load bearing device comprises a skeleton; the upper end of the skeleton is provided with an upper supporting plate which can move upwards relative to the skeleton; the lower end of the inner part of the skeleton is provided with a lower supporting plate which can move up and down relative to the skeleton; a force transfer device for transferring load and a force application device which is used for applying the load are arranged between the upper supporting plate and the lower supporting plate; the load bearing device is also provided with a testing device. According to the experimental device and the experimental method for simulating the anti-floating anchor-concrete plate composite structure, disclosed by the invention, design parameters of plane layout of different anchor rods, geometric parameters of a concrete plate, material strength and the like can be verified, so that optimal cooperative work of the anti-floating anchor-concrete plate composite structure can be achieved; load applying and counter force providing of the experimental device have the characteristic of self-balance system, so that an additional counter force balancing device does not need to be additionally arranged, and the anchor rod uplifting displacement and the concrete plate vertical displacement existing in the cooperative work when the anti-floating anchor-concrete plate composite structure plays an anti-floating role can be simulated; an assembling form is adopted, so that convenience is provided for the work of manufacturing, transporting, assembling and testing.

Description

Technical field: [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a test device and a test method for simulating an anti-floating anchor rod-concrete plate composite structure. Background technique: [0002] Environmentally friendly deep foundation pit construction is an important sustainable development topic in the field of civil engineering. Therefore, new structural systems, new design theories, and new construction methods have received great attention from government departments, experts and scholars. The construction of deep foundation pits has always followed the process of site leveling, support structure construction, precipitation construction, foundation pit earthwork excavation, and underground structure construction. The precipitation construction will take a long time and a large amount of groundwater, wasting a lot of groundwater resources. , breaking the original groundwater balance, causing uneven settle...
