Mechanical Property of Biomodified Geogrid and Reinforced Calcareous Sand

نویسندگان

چکیده

The strength and deformation properties of maritime geotechnical structures made primarily calcareous sand are critical for project safety. geogrid reinforcement is developed as a promising approach to improve the mechanical sand. This study investigates property biomodified via microbially induced calcite precipitation (MICP) process effectiveness A series unconsolidated undrained triaxial experiments were conducted evaluate behaviors reinforced (BGRCS), taking into consideration impacts layer, times biotreatment, confining pressure. Compared untreated geogrid, BGRCS distinctly changed due increase roughness, deviatoric stress-strain curves evidently hardening. Strength pseudocohesive force can be further enhanced by raising layer specimens, while internal friction angle also increases amplitude variation with biotreatment. pressure all intimately related specimens. interactions ribs particles analyzed using scanning electron microscope tests that could provide reference revealing mechanism BGRCS.

Cementing Material on Mechanical Property of Calcareous Sand

It is difficult to obtain high quality samples of natural material covering a range of densities and degree of cementation, so study on the sample preparation techniques with similar mechanical properties of natural samples are very important. Experiments were carried out to study the effects of cementation of different materials on the mechanical properties of calcareous sand, e.g., the effect...

Eccentrically loaded strip foundation on geogrid-reinforced sand

Results are presented for laboratory model tests conducted to determine the ultimate bearing capacity of an eccentrically loaded strip foundation supported by geogridreinforced sand. Only one type of sand at one relative density of compaction and one type of geogrid were used for the tests. The depth of the foundation was varied from zero to B (width of foundation). Based on the laboratory test...

Numerical Study of Cyclic Behavior of Shallow Foundations on Sand Reinforced with Geogrid and Grid-Anchor

When the foundations of structures under cyclic loading with amplitudes less than their permissible load, the concern exists often for the amount of uniform and non-uniform settlement of such structures. Storage tank foundations with numerous filling and discharging and railways ballast course under repeating transportation loads are examples of such conditions. This paper deals with the effect...

An Investigation on Behavior of Centrally Loaded Shallow Foundation on Sand Bed Reinforced with Geogrid

The study pertains to the investigation of the effect of embedment on the load carrying capacity and settlement of strip foundations on sand reinforced with geogrids. Geogrid being an inextensible reinforcing material is widely used all over the world mainly for retaining walls, abutments slope protection and below the foundation in poor soil. Some research works have been done the investigator...
