Research Abstract

Relationship between the inclination and the uneven settlement of house were investigated and their minimum numbers for which repair of the house is required to keep living were made clear based on the form survey regarding many houses damaged due to liquefaction of soil. It was also made clear that the seasonal fluctuations of groundwater table were similar to the change of monthly precipitation. Effects of several countermeasures against liquefaction were discussed through the actual case studies and the numerical analyses. Based on these evaluations of various countermeasures, effective soil improvement methods and liquefaction-resistant foundations were presented.
