Using relatively economical sensors and considerably less effort compared to structural measures, one can issue early warning when threshold value is reached. Observation of deformation is commonly used for specific slope, and warning is issued when deformation rate is suddenly increased. That observation can be combined with water content measurement to observe unique relationship between volumetric water content (VWC) and shear deformation. However deformation and VWC observation could not explain well the condition of soil strength during failure process. In this paper a proposal for using suction measurement and its threshold in rainfall-induced landslide monitoring is explained.

Sources for analysis were obtained from a full scale vacuum consolidation test data of Full Scale Test Geostructure Vacuum System Project in Pantai Indah Kapuk, Jakarta, conducted by PT. Geostructure Dynamics. The paper covers assessment of degree of consolidation and prediction of gain strength of soil due to dissipation of excess pore water pressure under vacuum preloading. The degree of consolidation and gain strength are calculated based on settlement data and pore water pressure data. The result from the analysis of consolidation with PVD-vacuum next is compared with the result of consolidation with PVD-embankment using PLAXIS 2D. In PLAXIS 2D, PVD is modeled in respect to geometric and permeability matching. Post test soil investigation data is also used to verify the analysis result.
Comparison result for this location shows that with the same equivalent load and same spacing of PVD, vacuum method can reduce consolidation time up to 43% or accelerate consolidation process up to 1.7 times faster than conventional preloading method.
