Abstract

The main purpose of this experimental study is to know the effect of improvement of soft soil by mixing it with granular materials on the properties of soft soil. The soil model was brought from a one construction project in Karbala, Iraq. Routine tests were carried out on the soft soil model alone, as well as for soft soil with specific percentage of granular materials. The model of cylindrical shape laboratory dimensions of 250 mm in diameter with a height of 300 mm. Eight different shear strength were used for laboratory model tests. Static loading tests were carried out on these model tests. It was found from results of model tests of improved soil that the averaged value of settlement reduction is 0.61 for all model tests, where the bearing capacity is increased by 31%.

混合颗粒材料对软土性质的影响
本试验研究的主要目的是了解软土与颗粒材料混合改良后对软土性质的影响。土壤模型来自伊拉克卡尔巴拉的一个建筑项目。常规试验分别对软土模型进行了单独试验,以及对特定比例颗粒材料的软土进行了常规试验。该模型为圆柱形,实验室尺寸为直径250毫米,高度300毫米。采用8种不同的抗剪强度进行室内模型试验。对这些模型试验进行了静载荷试验。改良土模型试验结果表明,各模型试验沉降减小平均值为0.61,承载力提高31%。
