PILE-TYPE LIQUEFACTION COUNTERMEASURE STRUCTURE AND CONSTRUCTION METHOD THEREOF
PROBLEM TO BE SOLVED: To provide a pile-type liquefaction countermeasure structure for the ground, capable of suppressing a lateral flow of a liquefaction layer easily at low cost without using special materials, and a construction method thereof.SOLUTION: A pile-type liquefaction countermeasure structure 1 comprises: a plurality of piles 3 constructed in the ground G including a liquefaction layer 5 so as to be spaced from each other; and plate-like structures 6 each of which is arranged so as to surround a head part 3a of each pile 3. The head part 3a of each pile 3 is fixed to the plate-like structure 6 over a predetermined height (t). The piles 3 are constructed after installing the plate-like structures 6. As described above, all piles 3 are fixed at side surfaces of the head parts 3a with the plate-like structures 6, thereby falling down of the piles 3 are prevented and a lateral flow of the liquefaction layer 5 is suppressed.
【課題】特殊な材料を用いることなく、安価かつ容易に液状化層の側方流動を抑制することができる、地盤の杭式液状化対策構造体およびその構築方法を提供する。【解決手段】液状化層５が存在する地盤Ｇに互いに離間するように構築される複数の杭３と、各杭３の頭部３ａを囲繞するように設けられた板状構造体６とを有し、各杭３の頭部３ａを所定の高さ（ｔ）にわたって板状構造体６に固定して杭式液状化対策構造体１とする。杭３を構築する際には、板状構造体６を設置した後に行う。このようにすべての杭３を頭部３ａの側面で板状構造体６により固定することにより、杭３の転倒が防止され、液状化層５の側方流動が抑制される。【選択図】図１
