The behaviour of collapsible soils (loess) is studied in this paper. Simulations of the stress and strain behaviour of the soil are made via the theoretical framework of Structured Cam Clay, with the effect of glutinous ingredient in loess suggested to be modelled as cementation effect. Based on the simulations, the capacity of the model for representing the behaviour loess is investigated, and...

Collapsible soils could widely be found in central part of Iran and has caused lots of problems for roads and railroads in that region. Appearance of wide cracks in the collapsible soil near the Tehran-Semnan railroad tracks has caused some worries regarding the safety and performance of the railroad. However, due to the high traffic of the railroad, it is impossible to block the road for remed...

Many countries in the word have loose and unstable soils encompassing a wide range ofgeological materials, which when inundated, may collapse and cause very significant distress to the structure. Stone columns have been used to strengthen such soils; even so, there are still cases where failure has occurred. In this technical note, the process and causes of stone column failure in reinforcing c...

In many regions in China there is a wide distribution of dead-weight collapsible loess that experience frequent disasters resulting in enormous losses to national property. Loess collapsibility is the leading cause of disasters in loess areas. Many international scholars are working collaboratively to avoid property losses and human casualties caused by the collapsible loess. Loess collapsibili...

The environmental problems caused by sewage sludge generated the growth of global population and urbanization are drawing attention scientific community worldwide to need developing sustainable solutions use that material. This work investigated possibilities using sludge, in wastewater treatment plants, as a strategy improve stabilize collapsible soils. Different soil–sludge mixtures, with 5%,...

Collapsible soil has a metastable structure that experiences large reduction in volume or collapse when wetting. The characteristics of collapsible contribute to different problems for infrastructures constructed on its such as cracks and excessive settlement found buildings, railways channels, bridges, roads. This paper aims provide an art review behavior all over the world, type soil, identif...

Abstract Collapsible soils are almost found in unsaturated states and involved significant engineering problems. Geotechnical challenges of such represented by the hydro-mechanical behaviour during wetting–drying cycles due to humidity climate conditions. The main objective this paper is investigate soil–water characteristic curve (SWCC) collapsible soils. In study, three types were investigate...
