Abstract
Nowadays the land subsidence and the liquefaction at residential grounds have been becoming more apparent. However, there are no particular investigation methods to determine their causes. This is because the grounds of detached residents where an investigation should be conducted are often very confined. In this study, a detailed analysis of N-value distribution at an embankment of a detached residence located on inclined bedrocks using improved Swedish weight sounding machine is conducted. The causes of land subsidence and the future tendency for the land subsidence are estimated. Also, a reinforcement method and material to fortify weak ground is proposed in this study.
