An assembled integral subway station model structure and its manufacturing method

Abstract

The invention relates to an assembly-integrated-type subway station model structure and a manufacturing method thereof and belongs to the field of underground structure earthquake resistance and rocksoil earthquake engineering model testing. The structure comprises prefabricated model components, cast-in-situ model components, model rebars and equivalent connectors; the model rebars are arranged;the equivalent connectors are arranged on the model rebars; prefabricated components are manufactured; the negative-second-layer prefabricated model component is installed; negative-second-layer supports are arranged; a baseplate is cast in situ; middle beams are installed; negative-first-layer supports are arranged; the negative-first-layer prefabricated model component is installed; a middle plate is cast in situ; top beams are installed; a top plate is cast in situ. The assembly-integrated-type subway station model structure can be applied to scale model testing of an assembly-integrated-type subway station, has the advantages that the main structural characteristics of a prototype structure can be reflected and the structure is economical and convenient to manufacture, and has wide application prospects.

Description

technical field [0001] The invention relates to the field of earthquake-resistant and geotechnical earthquake engineering model tests of underground structures, in particular to an assembled integral subway station model structure and a manufacturing method thereof. Background technique: [0002] The prefabricated building structure has many advantages such as fast construction speed, green environmental protection, low labor demand, and good economy. It is especially suitable for housing and infrastructure construction in urban areas. A large number of prefabricated and assembled above-ground construction projects have been completed across the country; in recent years, the construction method of prefabricated building structures has been used in the construction of subway stations, such as Yuanjiadian Station of Changchun Metro Line 2. [0003] It can be seen from the earthquake damage of the Daikai subway station in Japan that the subway stations in high-intensity areas w...

AI Technical Summary

Problems solved by technology

However, due to the limited size or bearing capacity of the current test equipment, especially the underground structure model test often needs to place the model structure in the model soil, so the scale ratio of the model test is generally large, and the geometric size of the model structure is generally small (often in millimeters)
