Abstract

The invention relates to a centrifugal model retaining wall test device, belonging to the research technical filed of soil pressure centrifugal model test. The device comprises a driving system, a model retaining wall structure, a measurement system and a displacement automatic control system of model retaining wall. The added displacement automatic control system of model retaining wall can guarantee the model retaining wall to be remained at rest during centrifugal acceleration is increased; by adopting an electric motor as the driving system, the displacement of the model retaining wall can be guaranteed to be slow, homogeneous and continuous, and a data acquisition system can be guaranteed to completely record a change process of soil pressure and soil body displacement field during the model retaining wall moves; and an improved structure of the model retaining wall leads the model retaining wall to keep translatory displacement model. The preliminary experimental result shows that the device has stable capability, reliable operation and convenient operation, and is suitable for the research of the rest condition of the rigid retaining wall and the soil pressure of a driving side.

Description

technical field

[0001] The invention is a test device specially used for carrying out an earth pressure centrifugal model test on a centrifuge to study the earth pressure problem, and its main technical field is the research technical field of the earth pressure centrifugal model test. Background technique

[0002] Soil retaining structures are widely used in civil engineering, water conservancy and hydropower, highway, railway transportation and other engineering constructions, and their purpose is to support the soil to keep it stable. The evaluation of earth pressure is a basic item in the structural design and stability analysis of earth-retaining structures, which is directly related to the safety, reliability and economical rationality of engineering design. The theory and application of earth pressure has become a basic topic in the field of soil mechanics and geotechnical engineering. The geotechnical centrifugal model test reduces the size of the geotechnical struc...
