Abstract Based on the collapsible loess particularity influence on engineering construction activities, combined with the existing research results, interior and exterior influencing factors of the loess collapsibility were analyzed. Microstructure characteristic of loess was the interior factor and was a decisive role, water and stress were the exterior factors and had the subordinate function to the loess collapsibility. The mechanism of loess collapsibility was the granular skeleton overhead structure being destroyed, the pore being collapsed and the particles were rearranged under the coordinate action of water and force.
