Abstract

 During the 2011 Great East Japan Earthquake in Japan, extreme liquefaction caused extensive damage to residential houses in the Kanto Plain region and resulted settlements and tilts larger than that was observed during the past earthquakes. This paper deals with a proposal of ground improvement technique by installing logs into loose sand layer as a soil liquefaction countermeasure for existing residential houses. First, a demand for countermeasure of residential houses and reasonable cost of construction were shown by questionnaire surveys . Next, small-scale shaking table tests were carried out to propose how to apply the technique of log pilling around existing residential house. As a result, the magnitude of settlements of the house which was improved by log piling with an inclination and the fixed top of logs became quite small.
