Embodiment Construction

[0023] The technical solution of the present invention will be further described below in conjunction with the drawings and specific embodiments.

[0024] As shown in the figure, the present invention includes a plexiglass model test box 2 erected on the test bench 1. The bottom of the model test box 2 is filled with sand, the filling height is 250-350mm, and the multi-layer building model is erected in the sand 3 and high-rise building model 4, a bracket 8 is arranged outside the model test box 2, and a plexiglass water container 5 is hung on the bracket 8. The bottom of the plexiglass water container 5 is higher than the top surface of the model test box 2 by 300~500mm, A switch 6 is provided at the bottom of the organic glass water container 5 and communicates with the bottom of the model test box 2 through a pipe 7; a layer of mesh 9 is laid on the bottom of the model test box 2.

[0025] The size of the above-mentioned model test box 2 is 600×400×400mm, and it is made of plexi...

Abstract

The invention discloses a foundation bearing capacity damage model test device. The foundation bearing capacity damage model test device is characterized in that sand grains are filled at the bottom of an organic glass model test box with the filling height of 250-350mm; multi-storey building models and high-storey building models are vertically arranged in the sand grains; a bracket is additionally arranged outside the model test box, and an organic glass water container is hung on the bracket; the bottom of the water container is higher than the top surface of the model test box, and the water container is communicated with the bottom of the model test box through a pipeline; and a mesh layer is laid at the bottom of the model test box. The invention simulates the overall process of building damage caused by the failure of the foundation bearing capacity, thereby meeting the visibility in classroom teaching. The invention provides an unprecedented model test device for civil engineering teaching tests, and provides a powerful analysis basis for technical personnel of the civil engineering field to analyze the building damage caused by the failure of the foundation bearing capacity.

Description

Technical field [0001] The invention relates to a foundation bearing capacity failure model test device, which can be used for higher education civil engineering teaching experiments. Background technique [0002] The foundation bearing capacity is a basic and important subject of soil mechanics research, and it occupies an important subject position in the teaching of civil engineering. Affected by the bearing capacity of the foundation, especially the influence of the rise and fall of the groundwater level, the phenomenon of inclination or even destruction of the building occurs from time to time. However, the process of building damage caused by the bearing capacity is generally difficult to record in engineering practice and cannot satisfy the intuitiveness of classroom teaching. It is necessary to develop a set of model test equipment to visually reproduce the process of building damage due to the failure of foundation bearing capacity. According to the investigation of ma...
