Problems solved by technology

In the traditional model test of underground building structure, the underground structure is usually buried in the soil box. Considering the particularity of the soil, the traditional model test of underground building structure often has problems such as poor test repeatability, difficult data collection, and long test period. , therefore, how to optimize the model test of underground building structure has great engineering significance

Embodiment 1

[0032] like figure 1 , 2 As shown, a simulated test component for formation resistance action characteristics includes a screw assembly, a simulated spring 2 and a contact end assembly. The screw assembly includes a screw core barrel 11 , a screw sleeve 12 and a loading rod 13 , and the contact end assembly includes a steel plate 31 and a wood block 32 . The screw core barrel 11 extends into the screw sleeve 12 from the rear end of the screw sleeve 12, the screw core barrel 11 and the screw sleeve 12 are provided with a spring washer 7, and the position of the spring washer 7 is set on the screw core. The barrel 11 and the positioning nut 4 on the screw sleeve 12 are adjusted so that the screw assembly can be applied to the simulated spring 2 with different stiffness parameters. Wooden block 32 is fixed on the steel plate 31 by screw 4, and the front end of steel plate 31 and screw rod sleeve 12 are all welded with connecting nut 5, and loading bar 13 is connected steel plat...

Embodiment 2

[0043] like Figure 5 , 6 As shown, a simulation test part of the stratum resistance action characteristic, the wooden block 32 is a cuboid wooden block used for the model test of the underground diaphragm wall structure and the model test of the elastic foundation beam structure, and the rest are the same as in Embodiment 1.

[0044] Figure 7-13 The schematic diagrams of the model tests applied to the transverse structure of the tunnel, the model test of the underground diaphragm wall and the model test of the elastic foundation beam are shown respectively.

Abstract

The invention relates to a formation resistance action characteristic simulation test part, which comprises a screw assembly, a simulation spring and a contact end assembly. The screw assembly comprises a screw core tube, a screw sleeve and a loading rod. The screw core tube stretches into the screw sleeve from the rear end of the screw sleeve. Spring washers are arranged on the screw core tube and the screw sleeve. The simulation spring is arranged between the two spring washers. The front end of the screw sleeve is connected with the contact end assembly through the loading rod. Compared with the prior art, by using different springs to simulate formation resistance, not only can the action characteristics of different formations to underground building structures be really reflected, but also the testing complexity due to a reason that the underground building structures are placed in soil bodies can be avoided.

Description

technical field [0001] The invention relates to an underground building structure test model, in particular to a simulated test component for ground resistance action characteristics. Background technique [0002] With the rapid development of the national economy, highways, hydropower, urban subways, railways, mines, national defense construction, municipal transportation, and underground commercial buildings have all undergone great development. Therefore, various forms of underground building structures are becoming more and more many. Since the environmental conditions of the underground building structure are essentially different from those of the upper building structure, for a long time most of the theories and methods applicable to ground engineering have been used to solve the problems of the underground building structure, so it is often impossible to accurately describe the various problems that occur in the underground building structure. a mechanical behavior....
