Session 01: Case Histories of Unexpected Behavior and Failure of Shallow, Deep and Other Foundations
Location
Arlington, Virginia
Date
13 Aug 2008, 5:15pm - 6:45pm
Abstract
The loess terrain exists in abundance in the Northeastern region of Thailand. The soil has a potential to collapse which has been caused by wetting. This study reports the characteristics of Khon Kaen loess under various conditions. A case study of foundation damage of building found on this soil is presented. The water supply pipe in front of a three-story building founded on shallow foundations in Khon Kaen University was broken. The loess supporting the foundation at the middle part of the building was soaked and the foundations were severely then settled. Some reinforced concrete beams and columns were investigated by civil engineers and it was found that some parts of the building have a big damage. This study also aims to investigate the suitability of this soil as a foundation layer by performing a 1g physical modeling test. The undisturbed samples used in the model test were excavated and prepared from field. The results show that the addition water can dramatically reduce the bearing capacity of the loess. The next series of tests were performed with the cement-treated loess samples and it was found that additional cement can increase the bearing capacity of the loess soil.

The Bearing Capacity of Cement-Treated Loess: A Case History of Khon Kaen Loess, Thailand
