Abstract
Conventional oedometer tests with reduced duration of loading have been done on highly organic soil so as to know the influence of loading duration on consolidation indices of the soil. Loading duration was varied between 20min and 60min, and the test results were compared with those obtained from the standard oedometer test in which loading duration is 1440min. Followings were concluded from the tests.
(1) When a soil is in the normally consolidated region, rapid consolidation test gives almost same results with those obtained from the standard oedometer test.
(2) However, when a soil is in the over consolidated region, settlement predicted by rapid consolidation test is smaller than that predicted by the standard oedometer test.
