Abstract

The invention discloses a miniature soil sample hydraulic consolidation loading system, which includes a main box with a built-in control system, a power drive device, a hydraulic loading device and a measuring device arranged in the main box, and the hydraulic loading device is arranged on a lifting platform. The power drive device is connected with the lifting platform to provide power, and the measurement device measures the pressure and displacement of the sample in the hydraulic loading device in real time through sensors. The invention is convenient for installation and debugging, has strong operability, can give quantitative pressure-displacement curves, and is convenient for the installation and disassembly of samples, and its detachable design allows taking out samples in any state during the test and performing high-precision CT scanning , providing an effective way and method for the consolidation test and microstructure observation of micro-soil samples.

Description

technical field [0001] The invention belongs to the technical field of testing in the field of geotechnical engineering, and in particular relates to a miniature soil sample hydraulic consolidation loading system, which is especially suitable for testing and observing the collapsibility of structural soil such as loess. Background technique [0002] After the loess and other structural soils are wetted by water under a certain pressure, the structure will rapidly fail and produce significant additional subsidence, which is called collapsibility. The collapsibility of loess can easily cause deformation of the foundation of engineering buildings, which in turn leads to uneven settlement of buildings. In addition, it can also induce geological disasters such as landslides under rainfall conditions. Therefore, scholars at home and abroad have long conducted a lot of research on the mechanism of collapsibility. At present, the indoor test technology for the collapsibility of loes...
