    Abstract: Expansive soil is prone to large volume changes (swelling and shrinking) that are directly related to changes in moisture. So the low bearing strength and high compressibility behavior of soil can cause severe damage to subgrade. In this research the enumeration of the strength of soil by adding different types of ground improvement materials like ... Show More

    Abstract: Gaza Strip faces large and accumulating shortfall between the built and needed houses due to a high natural population growth, very high population density, difficult political and economic conditions and a suffocating siege imposed, with a high unemployment rate. This has caused an increase in the ongoing gap between housing demands and supply. Th... Show More

    Abstract: The water content and permeability of silt and silt strata are significant in cities of Southwest China, and the seepage of underground passages in cities is unavoidable, which affects normal operation. More serious situation may occur when large-scale water gushing phenomenon and obvious structural deformation appears. After long-term and repeated... Show More

    Abstract: Compared with the traditional sampling quality detection method, the continuous compaction control technology has significant advantages in real time, full range and comprehensiveness. Therefore, this technology has gradually been widely used in the filling project. However, there are more than ten kinds of continuous compaction control methods, an... Show More
