Embodiment 1

[0046] This embodiment discloses a method for testing wall-soil interaction force, comprising the following steps:

[0047] 1) Prepare a rectangular parallelepiped soil sample, that is, the soil sample to be tested. The length, height, and width of the rectangular parallelepiped soil sample are L, H, and W, respectively, in the rectangular parallelepiped soil sample. In order to define each surface of the tested soil sample, in this embodiment, the two sides of the tested soil sample with a surface area of ​​L×H are respectively the front side and the rear side, and the two sides with a surface area of ​​H×W are respectively the left end surface and the right end face, and the two faces with a surface area of ​​L×W are the upper surface and the lower surface of the cuboid soil sample, respectively.

[0048] 2) The left end surface of the cuboid soil sample is in contact with the left wallboard, one side of the left wallboard is connected to the telescopic rod of the horizonta...

Embodiment 2

[0057] This embodiment provides a wall-soil interaction force testing system, which can implement the method described in Embodiment 1. Specifically, the system includes a bottom plate 1 with a horizontal upper surface, and the upper surface of the bottom plate 1 bears a soil sample 2 to be tested during the experiment.

[0058] In this embodiment, the measured soil sample 2 may be the cuboid soil sample described in Embodiment 1, that is, a cuboid soil sample whose length, height, and width are L, H, and W, respectively. In the cuboid soil sample, the two sides with an area of ​​L×H are respectively the front side and the back side, and the two sides with an area of ​​H×W are respectively the left end surface and the right end surface.

[0059] The upper surface of the base plate 1 is equipped with a front side panel 3, a rear side panel 4, a left side panel 7 and a right side panel 8, the upper end of the left side panel 7 is equipped with a left wall panel 9, and the upper ...

Embodiment 3

[0073] In this embodiment, the system described in Embodiment 2 is used to conduct a wall-soil interaction force test experiment.

[0074] 1) Prepare a rectangular parallelepiped quilt according to the experimental requirements in the cuboid experimental tank surrounded by the bottom plate 1, the front side plate 3, the rear side plate 4, the left side plate 7 and the right side plate 8, and the left wall plate 9 and the right wall plate 10. Soil sample 2. The contact surfaces of the bottom plate 1, the front side plate 3, the rear side plate 4, the left side plate 7 and the right side plate 8 are closely connected with each other and are impervious to water. The left wallboard 9 and the right wallboard 10 are in contact with both ends of the soil sample 2 to be tested. A loading plate 15 is placed on the upper surface of the soil sample 2 to be tested. The upper end of the loading plate 15 is in contact with the telescopic rod of the vertical loading device 18 , and the low...

Abstract

The invention aims to provide a test method and system for wall-soil interaction force. When the system disclosed by the invention is used for testing the force, after the primary sample making is executed, static soil pressure, active soil pressure and passive soil pressure can be respectively tested. Furthermore, before the wall-soil interaction force is tested, a soil sample is subjected to underground water soaking, underground water seepage, wet-dry circulation, rainfall, surface stacking or other actions, so that the actual condition of a retaining wall can be really simulated.

Description

technical field [0001] The invention relates to the test of wall-soil interaction force, specifically a test method for measuring wall-soil interaction force (including static earth pressure, active earth pressure and passive earth pressure), and a test system for realizing the test method . Background technique [0002] The wall-soil interaction problem is an important issue related to the safety and stability of landslides, slopes, foundation pits and other projects. The study of wall-soil interaction force (ie earth pressure) is the main way to study the interaction between soil and structures. According to the stress balance state of the soil behind the wall, the earth pressure acting on the back of the wall can be divided into static earth pressure, active earth pressure and passive earth pressure. [0003] Static earth pressure (earth pressure at res) means that when the retaining wall does not produce any movement or rotation under the thrust of the filling soil beh...
