Consolidation of naturally gassy soft soil
WebOct 9, 2024 · The degree of consolidation is an important parameter to evaluate the stability and consolidation effect of soft soil foundation. The degree of consolidation calculated by deformation often overestimates the actual degree of consolidation of soil, resulting in a large post construction settlement. WebAug 30, 2024 · Natural deposited soft clays are widely distributed across coastal regions in Asia, Europe, and North America [].The stress–strain responses of natural deposited soft clays are different from that of reconstituted or remolded soils because the soil structure is affected by the physiochemical forces in the process of deposition and sedimentations …
