Compound Instability Effect and Countermeasures of Pit-in-Pit in Collapsible Loess Strata
Applied SciencesThe construction of pit-in-pit has become increasingly challenging due to the bad geological conditions, particularly in collapsible loess strata. To understand its supporting characteristics and failure mode, it is necessary to study the composite ...

Study on the acid environment to the sensitivity of soil [PDF]
E3S Web of Conferences, 2021 In this research, the tests of collapsible sensitivity of loess in acid environment were carried out. On the basis of this experiment, this author draw on the experience of predecessors, and put forward two indexes of collapsibility sensitivity ...

Collapse of stone column foundations due to inundation. [PDF]
, 1990 An important problem encountered by foundation engineers involves partially saturated soils which possess considerable in-situ dry strength that is largely lost when the soils become wetted. Foundation design in such soils is difficult at best.

Loess as a collapsible soil: Some basic particle packing aspects [PDF]
, 2017 Loess is the most important collapsible soil; possibly the only engineering soil in which real collapse occurs. A real collapse involves a diminution in volume - it would be an open metastable packing being reduced to a more closely packed, more stable ...

Field study on soil collapsibility sensitivity [PDF]
E3S Web of Conferences, 2021 The sensitivity of loess collapsibility is generally considered as the difficulty, speed and size of loess collapsibility after water immersion. It is different from collapsibility of loess, but they are related to each other.
