Liquefied conversion measure fundamental structure and liquefied conversion measure construction method

摘要

Topic While it to be possible, to do liquefied conversion measure effectively, being simple, it offers the liquefied conversion measure fundamental structure and the liquefied conversion measure construction method whose operation cost is small. SolutionsFundamental structure A in order to do the liquefied conversion measure of the building in the time of earthquake, the lower part soil improvement body 1 where surface GL compared to the surface 1A is located to the lower part, plural post support holes h and h which penetrate lower part soil improvement body 1 up and down,The concrete pile 4,4 which is the plural non- deterioration characteristic posts to which top fits, the bottom is located to the lower part ground-water level WL compared to,And concrete pile 4,4,The wooden post 5,5 which to the bottom it is connected is locked,Plural friction piles P and P which are constituted by, hang from the underside 1B of lower part soil improvement body 1,It constitutes, the upper soil improvement body due to the foundation 3 of the aforementioned building which placing is done on 2 which was formed on lower part soil improvement body 1, and upper soil improvement body 2.
