Compression index clay
WebJun 26, 2024 · CONCLUSIONS. The project presents an attempt to predict compression index (CC) of marine clay with basic soil properties such as plastic limit, liquid limit, plasticity index, specific gravity and maximum dry density. For this, simple and multiple linear regression were performed in SPSS. The correlation coefficients obtained for … WebS c – consolidation settlement in the normally consolidated clay. C c – Compression index – to be evaluated from the laboratory testing. H c – Height of the clay layer. e 0 – Initial void ratio of the clay layer – to be obtained from the laboratory testing of undisturbed sample. σ’ 0 – Soil stress at mid-height of the clay layer
