Analysis of Combined Vertical and Radial Consolidation of Soil under Time-Dependent Loading

Fine-grained compressible soils are usually associated with strength challenges in the course of carrying structures, roadways, embankments, and other civil engineering facilities. In addition, due to their low permeabilities, take an awfully long duration achieve optimal consolidation, its attendant negative effects on facilities supported by soils. Engineering practitioners researchers have established efficacy vertical drains for accelerating consolidation process such through shortening horizontal flow distances, thereby stabilizing them improving load-bearing capacities. Application pre-loading surcharge provides additional drive rapid consolidation. The case time-dependent loading is quite topical because it reflects reality most appropriately. However, a rigorous analysis undergoing radial constant or time-varying conspicuously lacking literature authors publications this subject area largely based solution procedure assumed decoupling flows treating pore pressures as separate. This assumption, notwithstanding simplification introduces into mathematics problem, not physics. Therefore, theory presented herein aims at addressing that gap literature. Throughout analysis, coupled (vertical radial) flow, driven common water pressure, handled single process.
