There are many problems to predict the consolidation settlement on soft ground during the ground improvement period installing the vertical drains and preloadings. In these case, the important factor for the settlement controls are the predicting final consolidation settlement, time intervals also the height of preloading and so on.
For these purpose, an observational methods are proposed by several investigators such as Asaoka, hyperbolic, √t method.
The Asaoka method almost is coincide with the field measuring data, and the Hyperbolic method is slightly overestimated, on the other hand, √ method does not coincide with field data.
