ANALYSIS OF SETTLEMENT DATA FROM SAND-DRAINED AREAS

Rate of field consolidation is usually calculated from changes with time of piezometer readings. Presented here is a technique for analysis of field settlement observations to determine the field rate of consolidation and total settlement for sand-drained areas. This technique is developed from equal strain consolidation theory. The approach is demonstrated and verified using field data from three construction sites. For each site, the setttlement data were analyzed for rate of consolidation and total settlement. The coefficient of consolidation values extracted from the settlement data are compared to those calculated from changes in pore pressures. Total settlement indicated by the analysis is compared to the maximum settlement observed at each platform. Piezometers are important for controlling construction. However, by use of this technique the complete analysis of field data can be achieved independent of piezometer readings. /Author/
