GROUND FOR FIGHTING SUBSIDENCE DUE TO SHAKING BY TRAVELABLE INCLINATION, AND METHOD FOR CREATING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a ground for fighting subsidence due to shaking by a travelable inclination, which can effectively suppress such subsidence in the peripheral area of a non-liquefied layer structure and the surrounding ground thereof while suppressing the consumption of solidification material milk; and a method for creating the same.;SOLUTION: A plurality of pile type improving bodies 1 are installed in a non-liquefied layer S12 of a ground S1 for fighting ground surface subsidence. The plurality of pile type improving bodies 1 are arranged in a zigzag shape, or at a vertex of a square. The pile type improving bodies 1 are adjusted to have a BL ratio of 0.2-0.4. Thus the arrangement of the plurality of pile type improving bodies 1 is the arrangement for suppressing ground surface subsidence to prevent ground surface subsidence of the ground S1 for fighting ground surface subsidence.;COPYRIGHT: (C)2013,JPO&INPIT
