Comparison of consolidation curves for remolded mud volcano of Sidoarjo, Indonesia

Sidoarjo mud volcano (Lusi) is one of the most challenging problems regarding to the compressibility of fine grained soils in Indonesia. Understanding about compressibility behavior is essential to construct appropriate remediation program for this problems. Consolidation test has been conducted to investigate the compressibility behavior of Lusi mud volcano. In this study, the laboratory test result is compared with estimated value derived from several empirical equations. A simple equation can be used to predict e-log σ' curve very well by using the correlation between initial void ratio (e₀) and void ratio corresponding to unit pressure (e₁); and correlation between compression index (C_c) and physical properties of soils, such as liquid limit (w_L) or natural water content (w_n). This equation predict better than other available equations in literature when compared with laboratory test of Lusi mud volcano.
