In-situ loess collapsibility coefficient testing device and method
The invention discloses an in-situ loess collapsibility coefficient testing device and method. The device comprises a testing probe extending into a drill hole, an adjusting component arranged at the top of the drill hole and driving the testing probe to be adjusted in the depth direction of the drill hole, a water supply device arranged at the top of the drill hole and a data acquisition module connected with the testing probe. The method comprises the following steps: 1, forming two drill holes and lowering a loess collapsibility in-situ testing device; 2, adjusting an in-situ loess collapsibility coefficient testing device in one drill hole; 3, loading detection of a hole bottom soil body in one drill hole; fourthly, loading detection is carried out when water injection of a hole bottom soil body in one drill hole is saturated; 5, loading detection is carried out when water injection of the hole bottom soil body in the other drill hole is saturated; and 6, obtaining an in-situ loess collapsibility coefficient. The loess collapsibility coefficient measuring device is reasonable in design, convenient to implement and good in using effect, and can measure the collapsibility coefficient of loess at any depth.
