Parallel intelligent pressurized triaxial sample preparation technique

Abstract

The application relates to a parallel intelligent pressurized triaxial sample preparation technique and belongs to the technical field of indoor geo-techniques of civil engineering. The parallel intelligent pressurized triaxial sample preparation technique includes: (1) preparing before an experiment, to be specific, determining magnitude of pressure to be applied in the experiment process and experiment-required time according to stress history, depositional conditions and particle composition of experimental soil; (2) preparing instruments; (3) placing a soil sample; (4) compacting; (5) extracting the soil sample; (6) resetting the instruments, and preparing a next sample according the steps of (1) to (5). The parallel intelligent pressurized triaxial sample preparation technique enablestriaxial sample preparation pressure and time to be intelligently controlled, enables multiple samples to be formed at a time, ensures shorter sampling time and less disturbance upon a soil sample, overcomes the defect that traditional sample tube sampling is difficult and has certain engineering applicability.

Description

technical field [0001] The application relates to a parallel intelligent pressurized triaxial sample preparation process, which belongs to the field of indoor geotechnical technology of the civil engineering discipline. Background technique [0002] With the increase of construction projects on soft soil foundations in coastal areas, the test of soft soil mechanical properties has become an important content in current civil engineering. Triaxial test is a common experimental method to measure the mechanical properties of soft soil. The sample is cylindrical with a diameter of 3.91cm and a height of 8.0cm. During the experiment, 3-5 standard samples need to be made to test 3-5 different The mechanical properties of soft soil under confining pressure. Usually, manual compaction is used to uniformly compact the soil sample to achieve the target soil sample compactness, and manual demoulding is used. Due to the low efficiency of making samples one by one, it is difficult to a...
