An Evaluation on the Result of Pilot Test for Soft Grounnd Improvement in Asan

This paper is relate to the result of pilot test in Asan. In order to evaluate the characteristics of behavior and deformation in Asan and to analyse the effect of soft ground treatment, preloading, two types of paper drain and pack drain were constructed in the ground. Settlement gauges, pressure meters, pressure cells and ground water gauges were monitored and also borings and piezoncone tests were performed. As a result of analyse, every vertical drained area was consolidated over 90% degree of consolidation but preloaded area was not reached to 90%.
