Гипсосодержащий грунт — проблемный грунт, обладающий значительной прочностью в сухом состоянии. Он теряет прочность при увлажнении и намокании из-за существенного снижения прочностных параметров и несущей способности под нагрузкой вследствие растворения и разрушения цементирующих связей во влажном состоянии (просадка грунта происходит, когда из-за роста влажности ослабляются химические или физические связи между частицами грунта). Это приводит к чрезмерной осадке, влияющей на устойчивость инженерных сооружений. Гипсосодержащие грунты занимают около 1,865 млн км2 в мире. Процент гипсовых грунтов в Ираке составляет 6,7 % от общей площади гипсосодержащих грунтов в мире и около 28,6 % от общей площади этой страны.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Каменный столб — это метод улучшения грунта, используемый для стабилизации и укрепления слабых грунтов (грунтов низкой прочности) путем увеличения несущей способности (увеличения прочности), сокращения оседания и контроля над оседанием грунта (ускорение консолидации).</p></sec><sec><title>Результаты</title><p>Результаты. Целью данного исследования является изучение характеристик гипсосодержащего грунта, укрепленного каменными столбами. Лабораторные нагрузочные испытания проводились на укрепленных и неукрепленных гипсосодержащих грунтах с использованием большого стального ящика в качестве модели, каменных столбов различного диаметра (5, 10, 15 и 20 см) и фиксированной глубины (30 см).</p></sec><sec><title>Выводы</title><p>Выводы. Результаты показали, что осадка уменьшается с увеличением диаметра каменной колонны, а несущая способность увеличивается при увеличении диаметра.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Gypseous soil is one of the problematic soils that have substantial strength while dry but lose strength especially in wetting or saturation condition due to the significant reduction of its strength parameter and bearing capacity upon loading where gypseous cementing bonds have been dissolute and collapsed in the wet condition (Soil collapse occurs when increasing moisture weakens chemical or physical connections between soil particles), and therefore resulting in excessive settlements affects the stability of the engineering structures. Gypseous soils occupy about 1.865 million km2 in the world; the percent of gypseous in Iraq is 6.7 % of the total world gypsiferous area and about 28.6 % of the total area of this country.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Stone column is a soil improvement technique used for stabilization and reinforcing of soft soil (low strength soil) by increasing of bearing capacity (increasing strength) and reducing the settlement and control it (consolidation acceleration).</p></sec><sec><title>Results</title><p>Results. The aim of this study is to investigate the performance of gypsum soil reinforced by stone columns, where laboratory loading tests were performed on unreinforced and reinforced gypsum soil using big steel box as modeling and stone columns was have different diameters (5, 10, 15 and 20 cm) and fixed depth (30 cm).</p></sec><sec><title>Conclusions</title><p>Conclusions. The results showed that the settlement decrease with increase the stone column diameter and the bearing capacity increase when diameter increase.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>гипсосодержащий грунт</kwd><kwd>каменный столб</kwd><kwd>расчет</kwd><kwd>модель</kwd><kwd>диаметр колонны</kwd><kwd>глубина установки столба</kwd><kwd>укрепление</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gypseous soil</kwd><kwd>stone column</kwd><kwd>settlement</kwd><kwd>model</kwd><kwd>diameter of column</kwd><kwd>depth of column</kwd><kwd>reinforcement</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Zahmatkesh A., Choobbasti A.J.
