Popis: The average degree of consolidation of soft rock mass in the immediate vicinity of the base of drilled shaft or plate load tests was evaluated using the Biot Three-Dimensional Consolidation Theory. The compressibility parameters of soft rock mass were estimated using the contact pressure and displacement relationships obtained from the in situ drilled shaft and plate load tests. It was found that typical drilled shaft and plate load tests on soft rocks are drained to partially drained, with the average degree of consolidation dependent on the rock type and weathering condition, foundation diameter, and the loading stage. It was also determined that drained behavior is observed under service conditions due to the low compressibility of soft rocks in the early stages of loading.
