Abstract

 Damages of houses, sewer buried pipes, and roads subjected to severe liquefaction, which are distributed in mined areas at Fukashiba and Hiraizumi in Kamisu city, were clarified by analyzing the associated statistics. Road damages are related with differences in ground level which occur in the boundary between mined area and non-mined area. These differences might cause the partially damages of houses and the damages of sewer buried pipes such as vertical deformation or gaps at joints of pipes. It was also found that the deeper liquefaction layer causes the severer damage of houses.
