Description
Technical Field
The invention relates to an indoor rock-soil body model test device, in particular to a side slope side strip foundation model test device integrated with a miniature pile support, and belongs to the technical field of geotechnical engineering.
Background
In recent years, under the large background of rapid development of infrastructure construction in China, the foundation is sometimes required to be buried on the foundation beside the side slope under the influence of factors such as topography, economy and the like. For example, mountain roads are limited by terrain, and roadbeds are required to be arranged on the foundations beside the side slopes; when a bridge spans a valley or a traffic line, a pier foundation is sometimes required to be arranged on the top of a side slope; the power transmission line tower foundation in the mountain area is often arranged on a foundation adjacent to a side slope; when mining strip mines, sometimes roadbed is temporarily buried on the foundation beside the side slope. On one hand, the existence of the side slope can reduce the bearing capacity of the foundation, and on the other hand, the side slope deformation is increased due to the load-covering effect of the foundation, and the side slope stability is affected. Therefore, based on engineering safety considerations, there is a need to address the interaction mechanisms and stability issues of complex systems of slope-foundation composition.
And constructing a foundation beside the side slope, and ensuring the bearing capacity of the foundation and controlling the deformation of the side slope. In the existing foundation and foundation design specifications, corresponding solution suggestions are not provided for a complex system consisting of a side slope and a foundation. In engineering application, chang Yanyong plain foundation bearing capacity formula or correction of plain foundation bearing capacity formula does not form a unified method. Thus, theoretical and experimental studies of the fundamental load bearing capacity and failure mechanism of the side slope have relatively retarded.
The model test is an intuitive and economical method for revealing engineering destruction rules, and on one hand, the model test can provide basis and verification for theoretical research; on the other hand, the model test cost is lower than that of the engineering field test. The strip foundation is used as a foundation form with special size, the length-width ratio is large, the strip foundation can be used as an ideal plane strain model during theoretical treatment, and the obtained data can be used for engineering numerical calculation under the plane strain condition. Therefore, the model test of the side slope strip foundation is an effective method for solving the engineering problem of side slope and foundation coexistence.
However, the existing side slope strip foundation model test has less research, the problem of load eccentricity is often caused by foundation stress loading, particularly the problem of foundation overturning damage is more prominent, and meanwhile, no model test equipment for considering related matched micro pile support under the side slope strip foundation condition exists.
In summary, the theoretical and experimental research on the bearing capacity and the system stability of the side slope strip foundation is still insufficient, and the model test equipment of the micro pile support is not targeted, so that the research and development of the side slope strip foundation model test device integrated with the micro pile support can provide important technical support for revealing the interaction mechanism and stability control of the complex system consisting of the side slope and the foundation.
