Nowadays, soil reinforcement using polymer elements have been investigated by a number of researchers in order to increase the load capacity of soils. Reinforcing soils using fibers is a method of soil improvement, which offers a homogenous mixture in combination with soils, regarding their tensile strength. This combination maintains pressure loading capacity and properties in mutual resistant...

In this paper a laboratory study has been carried out on the effect of changing the type of soil filling cylindrical reinforcing elements from SM to GM on behavior of sandy soil. In this study the primary tests for evaluation of the impact of reinforced sand and gravel columns with diameters of 5 cm and heights of 15 cm subjected to vertical stresses of 50, 100, and 150 KPa were carried out in ...

ABSTRACT: Discrete element method offers insights into the soil behaviour at the microscopic level. In this investigation, a series of numerical direct shear tests is carried out by a three-dimensional discrete element code PFC. The size of the shear box is 6 cm long, 3 cm wide and 4 cm high. Non-spherical shaped particles are created by joining primary constitutive spherical balls together wit...

b ackground: mediterranean type of visceral leishmaniasis (vl) is present in different parts of iran. several studies have identified dogs as the main reservoirs of the vl caused by leishmania infantum in iran and other mediterranean regions. this study aimed to determine the seroprevalence of canine visceral leishmaniasis as animal reservoir host for human visceral leishmaniasis in boyer ahmad...

With the population growth and consequently the requirement for development of civil constructions, it is necessary to design appropriate foundations for resisting structural loads. Soil weakness in bearing capacity of geotechnical elements has forced the researchers to continuously follow a solution to compensate for this deficiency. Within the past two decades, many studies have been carried ...

The lunar soil is an ideal building material for future base construction. In order to improve the strength of soil, basalt with similar composition was used simulate due lack real and simulated reinforced sodium silicate. study direct shear mechanical properties by silicate solidification, a series tests SEM microstructure were carried out, stress-displacement whole process curve obtained. Inf...
