In many arid and semi-arid regions, collapsible soils are well-known to be problematic in nature negatively affect the performance of engineering structures. Gypseous soil considers one types soil. It represents a real challenge engineers due different problems encountered by projects implemented this The mineralogy, composition, fabric gypseous its ability deform when subjected wetting (due ch...

Screw piles are widely used in supporting structures subjected to pullout forces, such as power towers and offshore structures, this research investigates their performance gypseous soil of medium relative density. The bearing capacity displacement a single screw pile model inserted with various diameters (D = 20, 30, 40) mm examined study. the testing had gypsum content 40% bedding density 40%...

Gypseous soil exhibits problematic geotechnical engineering properties as they expand, collapse, disperse, undergo excessive settlement, owns a distinct lack of strength, and it is soluble. has metastable structure, with dissolvable minerals minimal quantity clay binding the particles together. When gypseous unsaturated, are quite potent. subjected to increased wetness, however, excess water we...

Gypseous soil, as is well known, includes a specific quantity of gypsum. Gypsum water-soluble salt with solubility (2.2-2.6) gram/liter in distilled - water. As result, the presence gypsum poses challenge when building structures on this since dissolves exposed to water, producing gaps between soil particles and so causing collapse. This study examines behavior shallow foundation rested gypseou...

The construction of embankment for roadway interchange system at urban area is restricted due to the large geometry requirements, since value land required such high, and available limited as compared rural area. One optimum solutions problem earth reinforcement technique which requires a construction. Gypseous soil from Al-Anbar governorate was obtained subjected various physical chemical anal...

Abstract One of the most critical engineering problems that occur in foundations machines resting on soil is problem transmission vibration from machine to foundation and then soil. This leads increased stresses layers settlement as well. In this article, an experimental model a rotary located gypseous sandy (36% gypsum content) has been studied. The weight with was 26 kPa subjected 10 Hz frequ...

Methods to improve bearing capacity of footing resting of collapsing soil can, in fact, take two approaches, improving soil strength properties and intrusion of reinforcing sorces into soil. The footing is modeled by a square steel plate 0.1 by 0.1 m. The footing is loaded as to have a stress of 40 kPa and settlement is receded in dry and in soaking conditions. Two depths of the geo-mesh reinfo...
