Translational soil pressure measuring-mode testing device

Abstract

The invention relates to the technical field of civil engineering, in particular to a translational soil pressure measuring-mode testing device which comprises an outer groove, an inner groove, an upper loading component, a lower loading component, multiple soil pressure measuring elements and a displacement measuring element. A transverse load-bearing body is positioned in a soil body, the soil pressure measuring elements are embedded in the soil body on the side face of the transverse load-bearing body, the displacement measuring element is arranged on the transverse load-bearing body, the upper loading component and the lower loading component are arranged horizontally and positioned on a same side of the transverse load-bearing body, one end of the upper loading component is abutted against the side wall of the outer groove while the other end of the same is connected with the top of the transverse load-bearing body, and one end of the lower loading component is abutted against the side wall of the outer groove while the other end of the same is connected with the bottom of the transverse load-bearing body. The upper loading component and the lower loading component load actions at the same time and push the transverse load-bearing body to move transversely by means of translation, so that soil pressure distribution law of the side face of the transverse load-bearing body under a translational displacement mode can be acquired through the soil pressure measuring elements and the displacement measuring element.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a translational earth pressure model testing device. Background technique [0002] At present, in deep foundation pit engineering, port engineering, bridge engineering, high-rise buildings and slopes, etc., load-bearing bodies (such as load-bearing piles and retaining walls) are widely used, and they mainly bear the effects of lateral forces and moments or effect of vertical loads. [0003] Taking loaded piles as an example, they can be divided into vertical loaded piles (such as pile foundations) and horizontal loaded piles (such as anti-slide piles, enclosure piles) according to their stress characteristics. In the mechanical analysis process of laterally loaded piles, the biggest difficulty lies in how to accurately determine the lateral earth pressure acting on the piles. On the one hand, the soil pressure on the side of the pile is related to the deformation size...

AI Technical Summary

Problems solved by technology

[0006] However, the cost of field tests is too high, and model tests have become an effective means to study the lateral soil pressure distribution characteristics of laterally loaded bodies (anti-slide piles, retaining walls, etc.)

However, there is currently a lack of experimental devices in this area
