Under the action of the dead weight pressure of the upper soil or under the combined action of the dead weight pressure and the additional pressure of the upper soil, the structure of the soil is quickly destroyed after being soaked by water to generate obvious additional sinking, which is called collapsible loess. Collapsible loess can lead to deformation of building foundation, foundation cracking, wall cracking, even become dangerous building until demolishing, and the canal bottom of building in loess can produce a large amount of collapsible deformation, brings immeasurable loss. Before building construction, whether loess has collapsibility is determined, and the determination can be made based on a collapsibility coefficient measured under a certain pressure by an indoor compression test. In the discrimination test, a sample is collected first, and the sample is subjected to a discrimination test of collapsibility.
