Soil pressure test device and correction computation method for soil pressure test

The invention relates to the technical field of pressure tests and discloses a soil pressure test device. The soil pressure test device comprises a pressurized panel, a pressure sensor and an elastic baffle, wherein the pressurized panel is connected with a to-be-tested structure through the pressure sensor and is in a shape adapted to the surface of the to-be-tested structure, the pressurized panel and the periphery of the to-be-tested structure are connected in a sealed manner through the elastic baffle, and closed test space is formed. The invention further discloses a correction computation method for a soil pressure test. The soil pressure test device is simple in structure, reliable in performance and high in test accuracy, and test data can reflect the stressed state of the to-be-tested structure more accurately.
