EARTHQUAKE RESISTANT STRUCTURE

PROBLEM TO BE SOLVED: To provide an earthquake resistant structure which can positively prevent liquefaction of the ground and collapse of a slope, and facilitates construction thereof in an existing mound or in the natural ground, and to provide an earthquake resisting method. SOLUTION: The earthquake resistant structure is implemented by driving drain pipes 2 each having a number of holes 4 formed therein along a longitudinal direction and having one end thereof almost acutely closed as a closed section 5, into the ground 1. By virtue of ground compaction effect due to driving of the drain pipes 2 into the ground 1, the strength of the drain pipes 2 per se, and the draining function of the drain pipes 2 per se, liquefaction of the ground at the time of an earthquake or local severe rain, collapse of the slope, etc. can be prevented. Further each drain pipe 2 is coated with Zn-Al-Mg-based plating, and therefore the drain pipe positively exerts anti-corrosive function. COPYRIGHT: (C)2006,JPO&NCIPI
