Buried pipeline test system

The invention discloses a buried pipeline test system, belongs to the technical field of buried pipeline tests, and is mainly used for simulating a stress-strain response process of a buried pipeline-foundation soil system. The technical problem to be solved by the invention is to provide the buried pipeline test system. Comprising a pipeline, a model test assembly used for simulating a pipeline-foundation soil system in an actual working condition, a settlement control mechanism used for simulating soil settlement, a pipeline internal pressure control assembly used for simulating the internal pressure of the pipeline, and an external load control assembly used for simulating various types of loads borne by the upper portion of the pipeline. The detection assembly is used for monitoring changes of related parameters in the model test assembly; the external power supply is used for supplying power; a plurality of assemblies are arranged in one test system to effectively simulate the stress-strain response proc
