Abstract

This paper presents a set of results of laboratory scale model footing tests conducted to determine the cyclic load resistance of sand beds reinforced with horizontal sheets of geogrid. The test results indicate that the total settlement decreases and the bearing capacity increases, with the increase in size of reinforcements and number of layers. With the inclusion of reinforcing sheets, ·the coefficient of elastic uniform compression decreases slightly; but this decreased value is valid up to the increased bearing capacity of the reinforced sand bed. There is significant improvement in the damping capacity upon reinforcing the sand bed as indicated by the comparison of the strain energies under the pressure-settlement curves obtained from cyclic plate load tests.

Cycle Plate Load Tests on Reinforced Sand

St. Louis, Missouri

This paper presents a set of results of laboratory scale model footing tests conducted to determine the cyclic load resistance of sand beds reinforced with horizontal sheets of geogrid. The test results indicate that the total settlement decreases and the bearing capacity increases, with the increase in size of reinforcements and number of layers. With the inclusion of reinforcing sheets, ·the coefficient of elastic uniform compression decreases slightly; but this decreased value is valid up to the increased bearing capacity of the reinforced sand bed. There is significant improvement in the damping capacity upon reinforcing the sand bed as indicated by the comparison of the strain energies under the pressure-settlement curves obtained from cyclic plate load tests.
