COMPARISON OF CONSOLIDATION CURVES FOR REMOLDED MUD VOLCANO OF SIDOARJO, INDONESIA

Abstract

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 (Cc) and physical properties
of soils, such as liquid limit (wL) or natural water content (wn). This equation predict better than other
available equations in literature when compared with laboratory test of Lusi mud volcano.
