Comparison of Rowe cell and oedometer test to determine peat soil consolidation parameters

Abstract

Many problems occur when building infrastructure on peat soil. That problem is large settlement. To know large settlement can do the testing. The consolidation test it consist of testing using a row cell and oedometer. The purpose of the two tools are different. This cell rowe tool can knowing the saturation value of sampling. Loading on this test with hydrostatic pressure. While oedometer cannot knowing the value of saturation, but the loading used can be static and cyclic loads. In this research take the sample used in Rawa Pening. The type of soil used in this area is peat soils. The method is use two tool and then comparison. From the results of the research implication the value of soil ability (Cc) and the coefficient of speed consolidation (Cv). In testing with rowe cell, the average soil Cc value was 0.499 and the Cv value was 256.89 cm2 per minute. Average soil pore cavity (e) of 15.00. Whereas in the evaluation with an oedometer, the soil Cc value was 0.64 and the Cv value was 154.54 cm2 per minute. The average soil pore cavity (e) is 0.77. From the results of testing prove a greater density index with rowe cell test.
