LIQUEFACTION MEASURE STRUCTURE OF STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a liquefaction measure structure of a structure for surely taking a liquefaction measure of the structure without being restricted by a plane shape and a surrounding state of the structure built on the ground. SOLUTION: An underground wall 3 is constructed in the ground 1 having the possibility of liquefaction so as to surround the ground just under the structure 2 built on the ground. A lower end part of the underground wall 3 is embedded by the depth L in the support ground 6. A restricting structure 7 continuing in the peripheral direction is constructed in a ring shape in an upper end part of the underground wall 3. The underground wall 3 is constructed by driving plural steel sheet piles 8 so as to surround the ground just under the structure 2.
