| Popis: | The non–availability and scarcity of suitable construction soils at several worksites has led to the increased usage of soils with inadequate engineering properties. With regard this reason there is a dire necessity for in–situ modification of foundation soils to improve their engineering properties and to obtain adequate bearing capacity. Despite several existing methods of soil improvement techniques, the soil reinforcement is considered to be prominent methods of ground improvement techniques. These days three dimensional method and technique of soil confinement using geocells is gaining reputation for enhancement of bearing capacity of such soils. In the present investigation, the laboratory experimentation was planned and performed various tests to explore the prospective advantages of embedding geocell reinforced sand mattress laid on soil subgrade (clayey soil). Test parameters that varied during the testing included are thickness of plain sand layer and height (clear distance) of geocell sand mattress laid above the clay bed. The experimental results have shown that a considerable enhancement in load carrying capacity. It could be achieved by the spreading of geocell reinforced sand mattress above the clayey bed. Further, it is noted from the test results that, almost 5–fold improvement in bearing capacity is attained by providing geocell reinforced sand mattress embedded in sand layer of thickness equal to twice the dimensions of the footing i.e., 2B (B is the width of footing). |
