Embodiment 1

[0081] Sand can be used as the filling material for the back of the wall.

[0082] Assemble the base of the model tank of the test device, the soil retaining board, the slideway, the cantilever retaining wall and connect the hydraulic jack to apply lateral displacement through the wall connection, embed the earth pressure gauge on the cantilever retaining wall and install The electronic dial indicator and the earth pressure gauge are connected to the data acquisition box through the data line, and the data is recorded through the dynamic signal acquisition and analysis system, and then the sand is filled in layers. It is divided into three layers, each layer thickness is 20cm, 30cm, 30cm, after each layer of filling is completed, it will be compacted and leveled. Within 30cm of the side close to the buried instrument, it will be compacted with a rammer, and the other parts will be compacted manually with a ramming plate. After each layer is compacted, it will be measured by irr...

Abstract

The invention discloses a soil pressure testing device and method for an anchor-plate-like retaining wall in different displacement modes. A problem that soil pressure distribution rules of the retaining wall in the different displacement modes cannot be tested and researched is solved by the soil pressure testing device and method. The soil pressure distribution rules of the retaining wall in thedifferent displacement modes are researched. The technical scheme is that the soil pressure testing device comprises a base, the base is provided with a test soil loading box, the test soil loading box is a frame-type structure, and the test soil loading box is filled with a soil body; one side wall of the test soil loading box is throughout provided with an anchor rod, the anchor rod is extendedto the outer side of the test soil loading box and is connected with a prestress loading device; and the top of the test soil loading box is provided with a cover load loading device, and the outer side of the side wall, throughout provided with the anchor rod, of the test soil loading box is connected with a lateral displacement loading device.

Description

technical field [0001] The invention relates to the technical field of road engineering, in particular to an earth pressure test device and method for an anchor plate type retaining wall under different displacement modes. Background technique [0002] With the development of retaining structure technology, the structural form of retaining wall is changing with each passing day, and the design concept is also constantly developing and optimizing. From the initial gravity retaining wall to the later semi-gravity, cantilever retaining wall, buttress retaining wall, pile plate retaining wall, anchor retaining wall, reinforced soil retaining wall, etc., each All kinds of retaining walls have their own characteristics and applicability. In recent years, in order to achieve the purpose of being economical, practical, lightweight and environmentally friendly, and at the same time meet the needs of high-fill subgrades, the retaining wall has developed towards a lightweight structur...
