LIQUEFACTION COUNTERMEASURE STRUCTURE OF CONSTRUCTION AND DESIGN METHOD OF LIQUEFACTION COUNTERMEASURE STRUCTURE OF CONSTRUCTION

摘要

PROBLEM TO BE SOLVED: To provide a liquefaction countermeasure structure of construction and a design method of liquefaction countermeasure structure of construction capable of effectively preventing (reducing) damage due to liquefaction without requiring large area or volume.;SOLUTION: A construction 15 is configured to reduce damage due to liquefaction on a construction 4 which is constructed including a pile foundation 3 in the ground G which has a non-liquefaction layer 2 on a liquefaction layer 1. The construction includes a spacer member 16 formed enclosing the pile foundation 3, with an upper end part of which is disposed in a non-liquefaction layer 2 on the liquefaction layer 1 and a lower end part of which is disposed in a non-liquefaction layer 5 under the liquefaction layer 1. The spacer member separates the liquefaction layer 1 at the pile foundation 3 side from the liquefaction layer 1 outside thereof.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
