The invention relates to a model test device for measuring composite foundation lateral deformation and layered sedimentation. The model test device comprises a counter-force groove, a loading plate, a vertical counter-force frame, a lateral counter-force frame, a vertical jack and a model groove and is characterized in that: the left side, the right side, the rear side and the bottom of the model groove are sealed; the front side of the model groove is sealed by adopting a high-strength organic glass plate; the right side of the model groove is provided with a lateral stress measuring mechanism; and a test soil body is arranged in the model groove. The model test device disclosed by the invention is mainly suitable for a composite foundation indoor model test with remarkable lateral deformation of a soft soil foundation and the like, can be used for simulating single-layer or double-layer and multi-layer foundations, has the advantages of simple and reasonable structure and convenient and feasible conversation, can realize indoor simulation of composite foundation lateral deformation and layered sedimentation under complex conditions and can provide basis for practical engineering composite foundation design optimization and reinforced mechanism analysis.
Description
technical field [0001] The invention belongs to the technical field of geotechnical engineering, in particular to a model test device for measuring lateral deformation and layered settlement of a composite foundation. Background technique [0002] In recent years, my country's high-speed railway and highway construction has developed rapidly. This large-scale new line construction will inevitably encounter soft foundations, and high-speed railways and highways put forward very strict control requirements for subgrade settlement. Stability, post-construction settlement and post-construction uneven settlement, various ground treatment methods have emerged as the times require. Composite foundation has been widely used as an economical and effective foundation treatment method, but its theoretical research on reinforcement mechanism and settlement calculation method lags behind engineering practice. Although the field test can provide more direct and reliable data, which can di...
