Large-scale three-dimensional comprehensive simulation test bench for geotechnical engineering

Abstract

The invention provides a large-scale three-dimensional comprehensive simulation test bench for geotechnical engineering. The test bench comprises reaction walls, reaction beams and a model case. The reaction walls are made of reinforced concrete and arranged on four peripheral sides of a foundation pit in a surrounding manner. A material conveying elevator shaft is arranged on one side of the foundation pit, and a test passage is arranged on the reaction wall on one side corresponding to the material conveying elevator shaft. The reaction beams cross the foundation pit to be disposed on the upper end faces of the reaction walls. Four peripheral sides of the model case are spliced by a plurality of horizontal loading plates, and the top of the model case is spliced by a plurality of vertical loading plates. The large-scale three-dimensional comprehensive simulation test bench for geotechnical engineering and proposed by the invention can realize real three-dimensional loading, and can be used for performing tests on large-sized physical models as well as physical model tests, of different functions, such as underground space and excavation simulation tests, foundation and slope engineering simulation tests under the conditions of rainfall and groundwater level rising and falling, dynamic response tests of pile foundations and soil around piles, segment simulation tests and structural member performance tests.

Description
