Problems solved by technology

[0004] The pressure chamber of the dynamic triaxial instrument is a sealed structure. At present, the pressure chamber and the base of the instrument are connected together by screws, but at least three screws are installed on the current dynamic triaxial instrument. When screwing the screw, it is necessary to ensure that the pressing force of multiple screws is consistent. The operation is troublesome, time-consuming and labor-intensive, and there is no leakage buffer and early warning device at the joint

Abstract

The invention discloses a saturated soft soil dynamic triaxial model test device and method, and belongs to the field of soft soil test devices. The saturated soft soil dynamic triaxial model test device comprises a triaxial apparatus body, the triaxial apparatus body comprises a base and a pressure chamber body, and the lower end of the pressure chamber body is fixedly connected with a connecting base; according to the scheme, an electromagnet adsorption mode is adopted to replace an existing screw connection mode, mounting and dismounting are convenient and fast, the sealing performance is enhanced by arranging the sealing block, the sealing strip and the pressure sealing ball, when leakage occurs, water penetrates through the sealing strip and enters the pressure sealing ball, the color developing block floats upwards to the perspective pipe, a tester can timely know the leakage condition so as to timely close a test instrument and avoid larger leakage, and leaked water is stored in the pressure sealing ball and the perspective pipe and cannot leak to the outside, so that the instrument is protected, and the trouble of cleaning is saved.

Description

technical field [0001] The invention relates to the field of soft soil test devices, in particular to a dynamic triaxial model test device and method for saturated soft soil. Background technique [0002] The so-called soft soil refers to the weak soil layer with low strength and high compressibility. Most contain certain organic matter. Due to the low strength of soft soil and large amount of sinking, it often brings great harm to road engineering. If it is not handled properly, it will have a great impact on the construction and use of roads. According to the characteristics, soft soil can be divided into five types: soft clay soil, muddy soil, silt, peaty soil and peat. The common soft soil in the subgrade generally refers to the cohesive soil in the state of soft or flowing. It is characterized by large natural water content, large void ratio, high compressibility, low strength, and has special engineering geological properties such as creep and thixotropy, and the en...
